INA Bearings

The INA NK-XL series needle roller bearing is a single-row radial bearing with a machined outer ring and no inner ring, designed to withstand high radial loads in very tight mounting spaces. It is used in applications where the shaft acts directly as the raceway, which simplifies the design and reduces the weight of the assembly. MR Accesorios Industriales supplies this series with the technical assistance needed to select the correct part number for each application.

The NK-XL series designation is read as follows: the letters NK identify a needle roller bearing with a machined outer ring and no inner ring; the first number that follows indicates the bore diameter (for example, in NK12/12-XL the bore is 12 mm); the second number, separated by a slash, indicates the overall width of the bearing (in NK12/12-XL, 12 mm). The -XL suffix indicates the manufacturer's current design, with dimensional and load capacity optimizations. Thus, NK16/20-XL corresponds to a bearing with a 16 mm bore diameter and 20 mm width.

These bearings are used in a wide variety of industrial equipment in Argentina: machine tools, pumps, compressors, gearboxes, conveyors, packaging equipment and agricultural machinery, among others. Their ability to withstand significant radial loads with a very low height profile makes them ideal for gearboxes, shaft supports and mechanisms where radial space is critical. They are also used in applications requiring high rigidity and rotational precision, such as grinding machine spindles or milling heads.

To correctly select an NK-XL bearing, take into account the radial load it must withstand, the rotational speed, the available lubrication and the type of sealing required. Since they do not have an inner ring, the raceway must be machined directly on the shaft, with the appropriate hardness and roughness; otherwise, it is recommended to combine it with a suitable inner sleeve. During assembly, ensure precise alignment between the shaft and the housing, and verify the radial clearance according to the application. Lubrication can be grease or oil, and in contaminated environments additional seals or retainers should be provided.

Regarding equivalences and interchangeability, needle roller bearings without an inner ring from other brands can replace those of the NK-XL series as long as the main dimensions (bore diameter, outer diameter and width) and load capacities match. It is essential to verify the tolerances and the type of design (open or sealed) to ensure equivalent operation. For critical applications, always consult our technical team before defining a replacement.

If you need an INA NK-XL series needle roller bearing, write to us via WhatsApp with the complete part number (for example, NK12/16-XL) or the dimensions of your application. At MR Accesorios Industriales we advise you so you can choose the most convenient option and we coordinate the quote promptly.

The INA HK series needle bushing is a radial needle roller bearing with a drawn outer ring and no inner ring. It is used when the shaft acts directly as the raceway and radial space is limited. Its compact design allows it to be mounted in machined housings with an interference fit, and it is common in applications requiring high load capacity in a small volume. MR Accesorios Industriales carries this line as a brand, with technical support to select the correct part number.

The HK series designation is read by numbers: the first two indicate the shaft diameter in millimeters and the next two the width of the bushing. For example, HK0408 fits a 4 mm shaft with 8 mm width; HK0810 corresponds to an 8 mm shaft and 10 mm width. In the examples HK0606, HK0608 and HK0609, only the width changes for the same shaft diameter. This logic allows you to quickly identify the size you need without a table.

In Argentine industry, INA HK series needle bushings are used in transmissions, pumps, compressors, machine tools and packaging equipment. They also appear in conveyor rollers, joints and lifting mechanisms. Since they have no inner ring, the shaft must have adequate hardness and be ground to function as a raceway. They are common in repairs where space is critical and bushings are being replaced with needle roller bearings.

To select the bushing, verify the shaft diameter and tolerance, the available width and the type of load. Mounting is done by pressing into the housing, with tooling that does not deform the drawn cup. Lubrication can be grease or oil depending on the environment; in contaminated applications, consider external seals or versions with a seal. Alignment between shaft and housing is key to avoid edge loads. If the shaft is not hardened, it is advisable to use a version with an inner ring.

Needle bushings are interchangeable between manufacturers by dimensional part number: the same shaft diameter and width usually has equivalents in other brands. However, verify tolerances, load capacity and type of drawn cup before replacing. INA is a reference in this family, and MR Accesorios Industriales carries the line as a brand. For equivalents, the safest approach is to compare the complete designation and consult with the supplier.

If you need an INA HK series needle bushing, send us the part number or the shaft and width measurements via WhatsApp. At MR Accesorios Industriales we help you confirm the correct variant and resolve the quote promptly. We can also advise you on mounting and lubrication so the repair goes well the first time.

INA NA-XL series needle roller bearings are radial bearings with high load capacity in a very compact cross-section design. They are used when radial space is limited and high loads must be supported with a compact assembly. MR Accesorios Industriales supplies this INA line, a brand that MR distributes, with technical advice to select the correct part number for your application.

The designation of these bearings combines letters and numbers that indicate the type and dimensions. The NA series corresponds to needle roller bearings with an inner ring; the number that follows, as in NA49/22-XL or NA69/28-XL, refers to the bore diameter according to an internal code. The XL suffix identifies the current INA design. In the examples NA4822-XL and NA4826-XL, the larger number indicates a different outside diameter within the same family. Knowing these codes helps you order the exact replacement.

These bearings are used in machine tools, pumps, compressors, electric motors, transmission equipment and roller systems in production plants. In Argentina, they are common in the automotive, metalworking, food and packaging industries, where mounting spaces are tight and radial loads are high. They are also found in lifting and continuous conveying equipment, where reliability and service life are critical.

To select the right bearing, take into account the radial load, rotation speed and available space. Verify that the shaft and housing have the appropriate hardness and surface finish. The assembly must ensure precise alignment to avoid lateral forces. Lubrication can be grease or oil depending on the operating conditions; in contaminated applications, consider additional seals or protection. A properly fitted assembly extends bearing life.

INA needle roller bearings can be interchanged with those from other brands that follow the same dimensional designation, such as SKF, FAG or NTN, as long as tolerances and design type are respected. It is important to verify the suffix and critical dimensions before replacing. At MR Accesorios Industriales we can guide you on the appropriate equivalent for your equipment, without compromising performance.

The Y-bearing (insert) is a ball bearing with a spherical outer ring and one or two sealed faces, designed to be mounted directly in split housings or in sleeves. The INA UC series is used in transmission, conveying and agricultural or industrial machinery. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you to choose the right insert for your application.

The UC series designation is read with the letter U followed by the letter C and a three-digit number that indicates the bore diameter. For example, UC201, UC202 and UC204 correspond to increasing sizes. Suffixes with a hyphen, such as UC201-08, UC202-09, UC202-10 or UC203-11, identify inch size variants or specific tolerances. To correctly interpret each code, have the equipment drawing or data sheet at hand and send us the complete code via WhatsApp.

In Argentine industry, UC series Y-bearings are found in belt conveyors, bucket elevators, mixers, mills, packaging lines and agricultural equipment such as seeders and harvesters. They are also used in fans, pumps and transmission systems where mounting on a shaft and split housing simplifies maintenance. Being inserts, they allow the bearing to be replaced without changing the housing, which reduces downtime in plants and workshops.

To select the insert, verify the shaft diameter, the locking type (set screw, eccentric or taper) and the sealing required according to the environment: dust, moisture or frequent washdowns. Mounting must be done with the housing aligned and the shaft clean; poor alignment accelerates wear of seals and raceways. Proper lubrication and correct internal clearance are key to service life. If you have doubts, consult us with the code and the working conditions.

Y-bearings from different brands are often interchangeable if the main dimensions, locking type and sealing match. The INA UC series can replace other equivalent inserts from manufacturers such as SKF, FAG or NTN, but always verify tolerances and the locking system. MR Accesorios Industriales sells leading brands and manufactures split housings, pulleys and ANSI chains.

If you need a UC series Y-bearing (insert), write to us via WhatsApp with the code or the equipment model. We quote you promptly and help you choose the correct variant. We can also advise you on complementary housings, seals and lubricants for your application.

The INA Y-bearing (insert bearing) of the GE-XL-KRR-B-FA series is an insertable bearing with a spherical outer ring, designed to be mounted in split plummer block or flanged housings. It is used in equipment where the shaft rotates and the housing stays fixed, with normal load and speed requirements. MR Accesorios Industriales supplies this line in Buenos Aires, Argentina, and helps you choose the exact part number for your application.

The designation is read in blocks. GE indicates the family of insert bearings; the number that follows is the shaft diameter in millimeters, for example 20, 25 or 30 in the part numbers GE20-XL-KRR-B-FA125 or GE30-XL-KRR-B-FA164. XL identifies the current generation of the product. KRR describes the sealing: contact with a rubber lip, designed to retain grease and stop contaminants. B refers to the design of the inner ring, and FA with its number distinguishes execution or treatment variants. The final suffix does not change the diameter: it changes the version.

These inserts appear in belt conveyors, bucket elevators, mixers, packaging belts and food or beverage processing lines. Also in aggregate processing equipment, concrete plants and agricultural machinery. In Argentina they are found in maintenance of manufacturing plants, warehouses and agro-industrial facilities, where quick replacement of the insert avoids disassembling the entire housing. Being a sealed and factory-lubricated bearing, it simplifies the workshop task and reduces unplanned downtime.

To select correctly, start from the shaft diameter you need and then define the sealing according to the environment: KRR with a rubber lip is the usual choice in the presence of dust or moderate humidity. Verify that the housing is compatible with the spherical outer ring and that the shaft locking system matches your mounting. During mounting, align the housing, avoid striking the insert and ensure the original lubrication. If the equipment works with heavy vibration, periodically check the clearance and the condition of the lip.

As for equivalents, insert bearings are compared between brands by shaft diameter, sealing type and outer ring shape, not by the full part number. The same diameter can have different sealing or locking executions, so interchangeability is confirmed by measuring and comparing the designation. If in doubt, send us the old part number or the shaft and housing dimensions: at MR Accesorios Industriales we verify it with you.

If you already have the insert part number, write to us on WhatsApp and we will send you the quote shortly. If you do not have it at hand, tell us the shaft diameter, the housing type and the working conditions, and we will guide you within the GE-XL-KRR-B-FA series. We handle technical maintenance and purchasing inquiries from Buenos Aires, Argentina, for the whole country.

The INA G-KRR-B-AS/V series Y-bearing (insert bearing) is an insertable bearing with a spherical outer ring, designed to be mounted in split plummer block or flanged housings to form a bearing unit. It is used in equipment where the shaft rotates and the housing remains fixed, with normal load and speed requirements. MR Accesorios Industriales sells this line, with technical advice to choose the correct part number.

The G-KRR-B-AS/V series designation is read in blocks. The letter G identifies the family of insertable bearings; the number that follows, as in G1010, G1012, G1014, G1015, G1100, G1102, G1103 or G1104-206, indicates the insert size. The KRR-B block indicates the type of sealing and the design of the outer ring, while AS2/V defines execution and locking variants. In part numbers with an additional hyphen, such as G1104-206, the numeric suffix distinguishes a mounting variant. To request a quote, provide the complete part number exactly as it appears on the equipment.

These insertable bearings are used in conveyors, belts, elevators, mixers, fans and agricultural or food machinery. In Argentina they appear in food plants, packing plants, mills, aggregate plants and packaging lines, where the environment may have dust, humidity or frequent washdowns. They are also found in water treatment equipment and textile machines. The combination of insert and housing allows the shaft to be aligned with normal mounting tolerances and the bearing to be replaced without disassembling the structure.

To select correctly, take into account the shaft diameter, the type of load and the environmental conditions. The KRR-B seal protects against dust and splashes; if there are pressure washdowns, it is advisable to evaluate an execution with greater sealing. Locking by set screws on the shaft requires that the seat be clean and free of burrs, and that tightening be done with the appropriate wrench. Factory lubrication is usually enough for the service life, but in humid environments or at high temperatures the relubrication interval should be reviewed. Housing alignment and correct radial clearance prevent parasitic loads.

As for equivalents, insertable bearings are interchanged between brands by standardized dimensions: bore diameter, outside diameter and width. A part number from another brand with the same dimensions can replace the original, but verify the locking type and the sealing, because they do not always match. The AS2/V and KRR-B suffixes may vary between manufacturers. If in doubt, send a photo of the nameplate or the part number engraved on the bearing and we will compare it with the INA G series.

MR Accesorios Industriales sells the INA line and adds more than 80 years of experience in industrial distribution.

The INA LR series support roller is a rolling component designed to withstand radial loads in guiding and support applications. Its robust construction and 2RSR sealing make it suitable for environments with dust, moisture, or splashes. It is used in conveyor systems, machine tools, and industrial equipment where precise and durable linear motion is required. MR Accesorios Industriales supplies this series backed by more than 80 years in the Argentine market.

The LR series designation is interpreted as follows: the letters LR identify the support roller family, while the numbers that follow indicate the outer diameter and width, according to the manufacturer's coding. The 2RSR suffix indicates that the roller incorporates double-lip seals on both sides, providing effective protection against contaminant ingress and lubricant loss. Examples such as LR50/5-2RSR, LR200-2RSR, or LR201-X-2RSR show variations in dimensions and configurations, including the letter X which may indicate a special design. To select the correct part number, it is essential to know the housing dimensions and the load to be supported.

These support rollers are used in a wide variety of industrial applications in Argentina. They are found in continuous conveying systems, such as conveyor belts and drag chains, where they act as guiding and supporting elements. They are also present in machine tools, packaging equipment, automated assembly lines, and lifting devices. Their ability to withstand radial loads and their resistance to contamination make them suitable for demanding environments, such as food processing plants, the wood industry, and the mining sector, among others.

For correct selection and mounting, it is important to consider the type of sealing required according to the environment: the 2RSR suffix offers an effective barrier against dust and moisture, but in applications with high temperatures or elevated speeds, other options may need to be evaluated. Proper lubrication is essential to extend service life; it is recommended to use greases compatible with the seals and operating conditions. The alignment of the roller with respect to the raceway must be precise to avoid undue axial loads and premature wear. Likewise, the internal clearance must be appropriate to compensate for thermal expansion and ensure smooth operation.

Regarding equivalences and interchangeability, INA LR series support rollers may be found with similar designations from other manufacturers, although dimensions and load capacities may vary. It is essential to verify technical specifications and tolerances before replacing one component with another of a different brand. MR Accesorios Industriales supplies the INA brand as part of its bearing line and can advise on compatibility with other brands available on the market.

INA LR series support rollers are cylindrical roller bearings with a thick-walled outer ring, designed to withstand high radial loads and transmit them onto raceways. They are used as support rollers in cams, linear guides, and lifting mechanisms, where the outer surface of the roller runs directly on a raceway. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina, with technical advice to choose the right variant.

The LR series designation is read in blocks: LR identifies the support roller family; the number that follows, as in LR5200 or LR5203, defines the size and load capacity. The suffixes indicate design variants: 2Z indicates double-lip sealing, TVH the polyamide cage type, and XL the current design generation. The intermediate letter X, present in LR5200-X-2Z-TVH-XL, distinguishes a design with modified profile or dimensions. Knowing these codes allows you to order the exact replacement.

In Argentine industry, these rollers are found in machine tools, packaging equipment, chain conveyors, presses, and high-demand cam systems. They also appear in the automotive industry, on assembly lines, and in linear motion equipment. Their ability to withstand considerable radial loads with a reduced diameter makes them suitable for confined spaces where a conventional bearing will not fit. MR Accesorios Industriales supplies them to plants and workshops throughout the country.

To select the correct roller, take into account the radial load, rotation speed, and environmental conditions. The 2Z sealing protects against dust and moisture, but if there are abrasive particles or frequent washing, a more robust seal should be evaluated. The TVH polyamide cage is suitable for moderate temperatures and high speed; in environments with elevated temperatures or shock loads, a metal cage may be required. Mounting requires precise shaft alignment and a raceway with controlled hardness and roughness.

When replacing a support roller, interchangeability between brands is not automatic: even if the main dimensions match, the sealing, cage, internal clearance, and load capacity may vary. Always verify the complete part number and housing tolerances. If you cannot find the exact reference, write to us via WhatsApp with the part number or measurements of the roller you need and we will help you identify the equivalent INA variant.

MR Accesorios Industriales supplies the INA line of support rollers with the technical backing of more than 80 years in the field.

We can also advise you on mounting, lubrication, and service life for your application.

INA support rollers of the NUTR series are cylindrical roller bearings with a thick-walled outer ring, designed to withstand high radial loads and moderate axial forces in rolling motion. They are used as cam rollers or support rollers in guides, cams and conveying systems, where the raceway is directly on the outer ring. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina, with technical advice to choose the correct designation.

The designation of the NUTR series is made up of the prefix NUTR followed by a number that indicates the outer diameter of the roller. In the examples NUTR15, NUTR17, NUTR20, NUTR25, NUTR30, NUTR35, NUTR40 and NUTR45, that number corresponds to the roller size: the higher the number, the larger the outer diameter and, in general, the higher the load capacity. The NUTR series does not carry additional suffixes in these references; the base part number already identifies a support roller with a thick outer ring, without an outer needle cage, suitable for rolling directly on the raceway.

These rollers are used in equipment that requires robust and compact rolling: linear guides, machine tool carriages, cam systems, chain conveyors, presses, packaging machines and handling equipment. In Argentine industry they appear in production lines, automotive assemblies, food plants and agricultural machinery factories, among others. Their design makes it possible to replace solid bushings or rollers with a solution with an integrated bearing, reducing wear and improving movement precision.

To select the correct NUTR roller, take into account the outer diameter your application needs, the overall width and the type of load: predominantly radial or combined with moderate axial. Verify that the raceway it will run on has the right hardness and finish; if the raceway is soft, the roller can mark it. Mounting is done with the corresponding shaft or pin, ensuring correct alignment to avoid lateral forces. Lubrication can be permanent or relubricable depending on use, and the roller seal protects against dust and contaminants.

As for equivalents, INA NUTR support rollers can be interchanged with references from other manufacturers that follow the same dimensional nomenclature, but there is no automatic equivalence between brands: each one defines its own tolerances, capacities and suffixes. Therefore, if you are replacing an existing roller, the safest approach is to compare the main dimensions and load conditions. If you have doubts, send us the part number engraved on the roller or the housing dimensions and we will help you identify the right option within the INA line.

MR Accesorios Industriales supplies the INA support roller line in Buenos Aires, Argentina, with more than 80 years of experience in the field. If you need a quote for a NUTR roller for your equipment, write to us on WhatsApp with the part number or the model you are looking for and we will reply promptly.

The GS series cylindrical roller thrust bearing is a component of the thrust bearing family: it is designed to support predominantly axial loads in one direction, with high load capacity in a small space. It is used in applications where thrust must be transmitted between rotating parts, such as gearboxes, machine tools, pumps and lifting equipment. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina, and helps you identify the correct part number for your equipment.

The GS series designation is read by its prefix and the number that follows. In examples GS81102, GS81103, GS81104 and GS81105, the prefix GS identifies the series, while the numeric block increases with the size of the component. Suffixes appearing after the number indicate design or execution variants within the same family. To choose the exact part number, it is best to take the complete designation stamped on the part or on the equipment drawing, not just the base number.

These thrust bearings are found in industries in Argentina such as metalworking, food processing, cement and mining, as well as maintenance workshops and process plants. They appear in spindles, rotary tables, gearboxes, centrifugal pumps and lifting equipment, where axial thrust is the dominant load. They are also used in machine tools and positioning mechanisms that require axial rigidity and low clearance. If your equipment works with thrust in one direction, this family is usually the right choice.

To select correctly, verify the load direction, the shaft and housing diameters, and the space available in the assembly. Lubrication and sealing are key: a cylindrical roller thrust bearing requires that the support raceways be ground and aligned, and that lubricant reaches the rolling zone. Alignment between the support parts prevents parasitic stresses and premature wear. During assembly, check that the contact surfaces are clean and flat, and that axial clearance remains within the manufacturer's specification.

Regarding equivalents, each manufacturer uses its own nomenclature for cylindrical roller thrust bearings, so codes should not be cross-referenced by similarity. The correct approach is to compare dimensions, load capacity and execution type, and confirm interchangeability with the equipment's technical data sheet. If the original part number is not available, an equivalent variant within the same series or from another brand can be sought, always validating dimensions and performance. MR Accesorios Industriales can help you with that technical comparison.

If you have the bearing part number at hand, send it via WhatsApp to MR Accesorios Industriales along with a photo of the part or the drawing. With that data we confirm the corresponding GS series variant and send you the quote shortly. You can also inquire about other sizes in the same family or equivalent alternatives if the original part number is no longer available.

The cylindrical roller thrust bearing is a component designed to withstand predominantly axial loads in one direction. Its design with cylindrical rollers and polyamide cage allows high load capacities and rigidity in applications requiring precision and strength. It is used in industrial machinery, gearboxes, pumps and transmission equipment. MR Accesorios Industriales sells this INA line in Buenos Aires, Argentina, with technical advice to select the right part number.

The designation of this series consists of a number indicating size and the suffix -TV, which identifies a glass fiber reinforced polyamide cage. For example, 81102-TV, 81103-TV and 81104-TV correspond to different shaft diameters. The base number defines the main dimensions, while the TV suffix indicates the cage type. Knowing this nomenclature makes identification easier when requesting a quote.

These bearings are used in applications with high axial loads and moderate speeds. In Argentine industry, they appear in speed reducers, centrifugal pumps, machine tools, lifting equipment and clutch systems. They are also found in assemblies requiring rigid and compact axial support, such as presses and positioning devices. Their ability to withstand unidirectional loads makes them suitable for shafts transmitting thrust in a single direction.

To select correctly, consider the direction of the axial load, its magnitude and lubrication conditions. These bearings accept oil or grease lubrication, and it is essential to ensure an adequate lubricant film to prevent premature wear. Alignment between the raceways is critical: any misalignment reduces service life. Mounting must be done with suitable tools, avoiding direct blows on the rollers. The TV cage tolerates moderate temperatures and offers good fatigue resistance.

Regarding equivalences, INA cylindrical roller thrust bearings can be interchanged with products from other brands that follow the same dimensional designation, such as SKF or FAG, provided tolerances and cage type are verified. It is important to confirm critical dimensions and load conditions before replacing a component. MR Accesorios Industriales can advise you on interchangeability.

If you need an INA cylindrical roller thrust bearing, send the part number or model by WhatsApp to MR Accesorios Industriales and we will quote you promptly. We have more than 80 years of experience in the field and we help you find the right solution for your equipment.

The INA K-TV series cylindrical roller thrust bearing is a component designed to withstand high axial loads in a single direction. Its steel cage design with cylindrical rollers allows precise operation in applications where the axial load is predominant. It is used in industrial machinery, transmission equipment and systems where high axial load capacity and rigidity are required. MR Accesorios Industriales supplies this brand throughout Argentina.

The K-TV series designation is interpreted as follows: the letter K indicates that it is a cylindrical roller thrust bearing with a cage, and the suffix TV indicates that the cage is made of polyamide reinforced with glass fiber, suitable for high speeds and moderate temperatures. Examples such as K81102-TV, K81103-TV and K81104-TV show the progression of the numeric code, which identifies the dimensions of the assembly. Each code corresponds to a specific size within the series, so it is essential to verify the exact number when requesting a quote.

In Argentine industry, these bearings are used in applications where axial loads are considerable and a compact assembly is required. They are found in gearboxes, machine tool spindles, positive displacement pumps, cranes and lifting equipment. They also appear in overhead cranes, presses and power transmission systems that operate with significant axial thrust. Their ability to withstand unidirectional loads makes them suitable for assemblies where the load acts in a single direction, often combined with other bearings that absorb radial loads.

To correctly select a cylindrical roller thrust bearing, consider the magnitude and direction of the axial load, the rotational speed and the environmental conditions. The assembly requires parallel and rigid support surfaces, since these bearings do not compensate for angular misalignment. Lubrication must be adequate: oil or high-viscosity grease depending on the speed and working temperature. It is important to verify the axial clearance and ensure correct fastening of the support washers, which are usually separate components. The TV cage allows moderate operating temperatures, so it must be checked that the limits recommended by the manufacturer are not exceeded.

Regarding equivalences and interchangeability, cylindrical roller thrust bearings from different brands may present differences in dimensions and load capacities. Therefore, when replacing a bearing, it is essential to compare not only the code but also the dimensions and operating conditions. The INA K-TV series is a reference on the market, and MR Accesorios Industriales can advise you on compatibility with other brands, provided complete technical data is available. Equivalences must not be assumed without verifying the specifications.

If you need a quote for an INA K-TV series cylindrical roller thrust bearing, write to us on WhatsApp with the complete code shown on your equipment or drawing. At MR Accesorios Industriales we reply promptly with the information you need to move forward. We can also help you identify the right replacement if you send us the measurements or the part number.

INA K series needle cages are components that guide and retain cylindrical needles in a radial arrangement. They are used in assemblies where radial space is limited and high load capacity is needed in a small volume. MR Accesorios Industriales supplies this INA line, a brand that MR carries, backed by more than 80 years in the industrial sector. If you need to identify the right cage for your mechanism, send us the part number on WhatsApp and we will advise you.

The designation of INA K series needle cages is read directly: the letter K identifies the family and the number that follows indicates the needle diameter or the reference dimension of the assembly, depending on the case. For example, K10, K12, K14 and K15 correspond to different sizes within the same series. They do not include additional prefixes or suffixes in this basic nomenclature, so the complete part number is interpreted as the specific cage size. To confirm the exact equivalence with your drawing or sample, it is advisable to verify the part number with our technical team.

These cages are used in a wide variety of industrial applications in Argentina. They are found in gearboxes, pumps, compressors, machine tools, transmission equipment and lifting mechanisms. They also appear in support rollers, cams and oscillating systems where needles must be guided precisely. Industries such as automotive, metalworking, food and petrochemical use them to replace or manufacture compact rolling assemblies. MR Accesorios Industriales supplies them to serve both maintenance workshops and equipment manufacturers.

To select a K needle cage, take into account the diameter and length of the needles it will house, as well as the shaft and housing diameters. The cage must allow the needles to rotate freely and keep them aligned. It is essential to verify lubrication: these cages usually require oil or grease that guarantees a film between needles and raceways. During assembly, avoid impacts that deform the cage and make sure the needles roll without jamming. Alignment between shaft and housing also influences the performance and service life of the assembly.

Regarding equivalences and interchangeability, needle cages are identified by their dimensional designation, which may coincide between different manufacturers. However, it is not advisable to assume that a part number from another brand is identical without verifying tolerances and surface treatment. INA is a reference in this type of component, and its K series is often found in replacement catalogues. If you need to replace an existing cage, the safest approach is to compare the actual dimensions of the needles and the assembly, not just the part number. Our team can help you with that verification.

If you already have the part number of the INA needle cage you need, or if you want us to help you identify it, write to us on WhatsApp. At MR Accesorios Industriales we reply shortly with the technical information and the corresponding quote. We can also advise you on alternatives within the same series if the exact part number is not available. Send us a photo or the assembly drawing and we will review it.

Crossed roller bearings are precision bearings with cylindrical rollers arranged in a crossed pattern, which allows them to withstand radial loads, axial loads and moments in any direction. They are used in applications requiring high rigidity and rotational accuracy, such as rotary tables, machine tool heads and measuring equipment. MR Accesorios Industriales supplies the INA line in Buenos Aires, Argentina, with technical advice to select the correct part number.

The SX series designation is interpreted in blocks: the initial letters identify the crossed roller family, and the numbers that follow indicate dimensions and design variants. For example, in SX0118/500 the numeric suffix refers to a specific size, while in SX011814 the combination of digits defines diameter and width. The examples SX011818, SX011820, SX011824, SX011828, SX011832 and SX011836 show how the coding varies according to size. To correctly interpret each case, it is necessary to consult the corresponding data sheet.

These bearings are used in industries that demand precision and rigidity, such as metalworking, automation, robotics and machine tool manufacturing. In Argentina, they are found in positioning tables, rotary axes of inspection equipment, precision gearboxes and solar panel orientation systems. They also appear in medical and laboratory equipment. Their ability to withstand combined loads makes them suitable for assemblies where space is limited and exact rotation is required.

To select a crossed roller bearing, take into account the required load capacity, rigidity, internal clearance and type of sealing. Lubrication is critical: it can be grease or oil, depending on the speed and working temperature. Mounting must ensure precise alignment between the inner and outer rings, since small misalignments affect service life. Preload and clearance are adjusted according to the application. Always follow the manufacturer's recommendations for mounting and lubrication.

Regarding equivalents and interchangeability, crossed roller bearings from different brands may differ in dimensions and tolerances, so they are not always directly interchangeable.
