The NTN B series angular contact ball bearing is a single row bearing with offset raceways, designed to withstand combined radial and axial loads in one direction. It is used where rotation precision and axial rigidity are decisive: spindles, pumps, gearboxes and transmission equipment. MR Accesorios Industriales sells the NTN line in Buenos Aires, Argentina, and quotes the exact part number you need on WhatsApp.

The B series designation is read from the size number and the suffix that accompanies it. In the examples 7200B, 7201B, 7202B, 7203B, 7204B, 7205B, 7206B and 7207B, the initial number identifies the dimensional series and the following digit the bore size; the final letter B indicates the contact angle of the series. This code defines the part unambiguously, so send us the one shown on the drawing or on the old bearing.

These bearings appear in machine tool spindles, centrifugal pumps, compressors, gearboxes and transmission cases, and in process equipment in the food, chemical and metalworking industries. In Argentina they are also found in industrial fans and in assemblies where axial thrust must be absorbed in addition to radial load. When the equipment works with load in one direction, the B series is the single row option; if the thrust goes in both directions, they are mounted in pairs.

For selection and mounting, internal clearance, sealing and lubrication must be taken into account. The B series is usually open, so sealing is handled with radial shaft seals or labyrinths in the housing. Mounting requires careful alignment and controlled preload: uneven tightening or a misaligned seat shortens bearing life. Lubrication can be grease or oil depending on speed and working temperature, and axial clearance should be checked before starting up the equipment.

Equivalences between brands are handled by the dimensional code and the contact angle: the same size may appear with different suffix letters depending on the manufacturer, and they are not always interchangeable without verifying the angle and clearance. If you bring an unidentified part or another brand's code, at MR Accesorios Industriales we indicate the equivalent NTN reference and quote it for you. Interchangeability is always confirmed against the drawing and the equipment's load conditions.

The UEL series designation is read in blocks. The letters UEL identify the type: insert bearing with extended sealing. The first number indicates the diameter series: UEL2 corresponds to the light metric series and UEL3 to the medium metric series. Then comes the size code, which may be just the basic number, as in UEL204D1, or include a numeric suffix separated by a hyphen, as in UEL204-012D1, where that number defines the bore diameter in inches. The suffix D1 indicates a design variant of the seal and cage. Thus, UEL205-013D1 is a series 2 insert with a 13/16 inch bore, and UEL206-101D1 is series 2 with a 1 inch and 1/16 bore.

These insert bearings are used in belt conveyors, bucket elevators, mixers, mills, washing equipment and any machine with transmission shafts rotating at moderate speeds. In Argentina you find them in food, cement, ceramic and meat processing plants, and in the field, on seeders and harvesters. The combination of a spherical outer ring and a split plummer block housing allows initial shaft misalignments to be corrected, which is key in equipment assembled on welded or folded sheet metal structures.

To choose the correct insert, start from the shaft diameter and the type of housing where it will be mounted. The UEL series has an inner ring that protrudes on one side, which requires a housing with a compatible seat. The extended seal protects against dust and splashes, but if the environment has a lot of water or fine particles, an additional seal should be evaluated. During mounting, check that the shaft is clean and free of burrs, and that the insert seats without blows. Factory lubrication is sufficient for most applications; in severe environments, relubrication should be scheduled.

If you need to replace an insert bearing from another brand, the most practical approach is to compare by dimensions: bore diameter, outer diameter and overall width, plus the type of shaft locking.

For example, in 230/500B, the code 230 corresponds to the outer diameter and width series, and 500 indicates the bore diameter in millimeters. The final letter B confirms the execution with brass cage. This nomenclature allows quick identification of the main characteristics of the bearing.

These bearings are used in a wide variety of industrial applications in Argentina. They are common in large gearboxes and reducers, in kiln and dryer rollers, in machines for the cement industry, in crushing and grinding equipment, in cranes and lifting equipment, and in general in any system where combined loads and the possibility of shaft deflection exist. Their self-aligning capability makes them ideal for assemblies where perfect alignment between supports cannot be guaranteed, or where thermal and mechanical deformations are significant.

To correctly select a B series spherical roller bearing, it is essential to consider the radial and axial load it must withstand, as well as the rotation speed and environmental conditions. Sealing is a key aspect: there are open and sealed versions; sealed ones protect against contaminants and retain lubricant, extending service life. Internal clearance must also be evaluated according to the application and mounting; adequate clearance prevents thermal overloads. Lubrication can be with grease or oil, and must be chosen according to speed and operating temperature. During mounting, it is recommended to use suitable tools and verify initial alignment to take advantage of the self-aligning capability without forcing the bearing.

Regarding equivalences and interchangeability, NTN B series spherical roller bearings can be interchanged with products from other brands that follow the same dimensional and execution designation. It is important to verify that the main dimensions (bore diameter, outer diameter and width) match, as well as the cage type and internal clearance. Although international standards facilitate interchangeability, it is always recommended to consult the technical specifications of each manufacturer to ensure optimal performance.

They are used in electric motors, pumps, fans, gearboxes and power transmission equipment in general.

The designation of these bearings is read in two parts. The four-digit number identifies the size: the first two indicate the diameter series and the last two the bore diameter. Thus, 6008ZZ and 6012ZZ share the series and change the shaft size, just like 6018 ZZ or 6020 ZZ. The ZZ suffix defines the closure: two steel shields, one per side, that retain the lubricant and block the ingress of coarse dust without adding contact or appreciable friction.

In Argentine industry these bearings appear in general-purpose electric motors, centrifugal pumps, fans and extractors, conveyor belts, machine tools and packaging equipment. They are also found in agricultural implements, compressors and power transmission systems where a compact support is needed, easy to mount and with very little maintenance requirement throughout the service life of the equipment.

To choose well, take into account the type of closure: ZZ is fine in dusty environments without pressurized liquids, while if there is water or steam a contact seal is preferable. Also verify the factory lubrication, internal clearance and alignment of the housing and shaft, because a misaligned support shortens the bearing life. Mounting is done with a press or puller, never by striking the raceway.

When the customer brings the part number from another brand, interchangeability is resolved by dimensions: bore diameter, outer diameter and width. Deep groove ball bearings of equivalent series between manufacturers usually share those dimensions, and the closure suffix may vary from one brand to another. If the part has no identification, it can be identified by measurement and comparison with the corresponding standard.

If you need an NTN deep groove ball bearing with ZZ closure, send the complete part number via WhatsApp to MR Accesorios Industriales and we will quote it shortly. If you have an unidentified part or the part number from another brand, send us the measurement or the model and we will indicate the corresponding equivalent.

The NTN EC series deep groove ball bearing is a precision component for supporting radial and axial loads in rotating equipment. Its single-row ball design and deep raceways allow it to run at high speeds with low maintenance. It is used in electric motors, pumps, fans and industrial drives. MR Accesorios Industriales sells this line with ZZ sealing for dusty or humid environments.

The EC series designation is read with the number indicating the bearing size and the suffixes defining its features. For example, EC-6002ZZ corresponds to a bearing from the 60 series with metal seals on both sides. The codes EC-6003ZZ, EC-6004ZZ and EC-6005ZZ follow the same logic: the number increases with the bore diameter, and the ZZ suffix indicates the protection. Knowing this nomenclature lets you quickly identify the part you need.

In Argentine industry, these bearings are found in low- and medium-power electric motors, centrifugal pumps, fans, conveyor belts and machine tools. Metalworking shops, food plants and textile factories use them for their robustness and ease of assembly. The EC series with ZZ sealing is common in environments with dust, chips or moderate humidity, where protection is required without sacrificing speed.

To select the correct bearing, take into account the shaft diameter, the type of load and the environmental conditions. ZZ sealing provides a barrier against contaminants and retains lifetime lubrication. It is essential to verify shaft and housing alignment, and to mount with the right tools so as not to damage the raceways. If the equipment operates at high temperatures or with combined loads, contact us and we will advise you.

NTN EC series bearings are interchangeable with other brands that follow the same international nomenclature. If you bring the code from another brand or an unidentified part, we can tell you the exact equivalent. Interchangeability is based on standardized dimensions, but it is always advisable to confirm tolerances and internal clearance according to the application. At MR Accesorios Industriales we quote the exact code or size you need.

The HJ angle ring is an auxiliary component that mounts on the inner ring of NU, NJ and NUP series cylindrical roller bearings. Its function is to retain the rollers axially and facilitate bearing disassembly, since it allows the inner ring with rollers to be removed without dismantling the assembly. It is made of bearing steel and is sold as a separate part for replacement or for use in assemblies that require additional axial guidance.

The HJ designation is completed by a number that indicates the size of the bearing it combines with. For example, HJ204 corresponds to a bearing of the 204 series, HJ205 to the 205 series, and so on up to HJ211. The number is not a direct measurement, but identifies the compatible bearing: the HJ ring is selected according to the code of the cylindrical roller bearing to be mounted. In cases where the bearing has suffixes, such as NU or NJ, the HJ ring keeps the same numeric reference.

This type of ring is used in applications where the cylindrical roller bearing must support axial loads in one direction and, at the same time, allow frequent disassembly. It is common in gearboxes, industrial pumps, machine tools, mining and conveying equipment, and in general in any assembly with NU or NJ bearings that requires axial retention. In Argentina, it is found in equipment maintenance in the food, petrochemical and steel industries.

To select the correct HJ ring, the cylindrical roller bearing it is intended for must be identified. The number following HJ must match the bearing code: an HJ208 goes with a 208 bearing. It is important to verify that the bearing is of the appropriate series, since the ring rests on the inner ring and must fit into the corresponding groove. During mounting, it is recommended to lubricate the contact surface and ensure correct alignment to avoid premature wear.

NTN HJ rings are interchangeable with those of other brands that manufacture cylindrical roller bearings with the same designation. If the customer has the code from another brand, the NTN equivalent can be quoted. Interchangeability is based on the standardized dimensions of the bearing, so an HJ from one brand can replace that of another as long as the base bearing is the same. To confirm equivalence, simply send the complete bearing or ring code.

At MR Accesorios Industriales we sell NTN HJ angle rings for the entire cylindrical roller bearing line. If you need an HJ204, HJ205 or any other size in the series, write to us on WhatsApp with the bearing or ring code and we will quote it promptly. We can also advise you on compatibility with the bearings you already have mounted.

The HJ angular ring is an auxiliary component that mounts on the inner ring of NU and NJ series cylindrical roller bearings. Its function is to retain the rollers axially and facilitate assembly of the unit, especially in applications where the bearing works with combined loads or where mounting requires precise position control. MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina, with more than 80 years of experience in the field.

The designation of these rings combines the letters HJ with a two- or three-digit number and the suffix E. The central number corresponds to the size of the bearing for which it is intended: for example, HJ204E goes with a bearing of series 204, HJ205E with one of series 205, and so on. The suffix E indicates that the ring is optimized for reinforced-design cylindrical roller bearings, which are the ones that predominate in the market today. Knowing this logic allows you to order the correct ring without ambiguity.

These rings are used in a wide variety of industrial equipment in Argentina: conveyor belts, gearboxes, centrifugal pumps, fans, machinery for the food industry, mining equipment and aggregate processing plants, among others. In all cases, the HJ ring provides additional axial guidance that improves bearing stability and simplifies mounting when the shaft works in a horizontal position or with moderate vibration.

To select the correct ring, take into account the complete code of the bearing for which it is intended. The HJ mounts on the inner ring and must match the bearing series in diameter and width. If the bearing already has an integrated angular ring, there is no need to add another. During mounting, verify that the support faces are clean and free of burrs, and lubricate with the same grease or oil you use in the bearing. Alignment between shaft and housing is key for the ring to work without lateral stresses.

Although each manufacturer has its own nomenclature, NTN HJ rings are usually interchangeable with those of other brands that use the same numerical designation. If you have the code from another brand, we can help you find the equivalent. It is always advisable to verify the critical dimensions before replacing a component, especially if the bearing is from an old series or imported equipment.

If you need an HJ angular ring for your cylindrical roller bearing, write to us on WhatsApp with the exact code (for example, HJ210E) and we will quote it shortly. At MR Accesorios Industriales we work with the NTN line and can advise you so you choose the component that best suits your equipment.

The NTN 811 series cylindrical roller thrust bearing is a component designed to withstand high axial loads in one direction.

It is used in applications where precision and durability are critical, such as gearboxes, machine tool spindles and lifting equipment. MR Accesorios Industriales sells this series with the technical backing of more than 80 years in the Argentine market.

The 811 series designation is interpreted by its base number: the first digits indicate the type of cylindrical roller thrust bearing and the following ones the size. The usual suffixes, such as WS, identify the shaft washer, which in these mountings is usually supplied separately. For example, WS81100 corresponds to the shaft washer for bearing 81100. Knowing this nomenclature makes it easier to select the correct component according to the available space and the load to be supported.

These bearings are used in industries such as metallurgy, cement, mining and machine tools. In Argentina, they are common in presses, extruders, cranes and earthmoving equipment. Their ability to withstand pure axial loads makes them ideal for applications where axial space is limited and high rigidity is required. They are also found in gearboxes and milling machine spindles, where axial precision is essential for surface finish.

To select the right bearing, it is crucial to consider the axial load, the rotation speed and the environmental conditions. The mounting must ensure precise alignment between the shaft and the housing; any misalignment reduces service life. Lubrication can be grease or oil, depending on speed and temperature. In applications with contaminants, additional seals should be evaluated. The WS washer must be mounted with the correct fit to prevent slipping.

NTN cylindrical roller thrust bearings are interchangeable with those of other brands that follow the same dimension standard. When replacing a bearing, it is important to check the critical dimensions: shaft diameter, outer diameter and height. The NTN 811 series is usually equivalent to similar series from other manufacturers, but compatibility must always be confirmed.

The NTN S series self-aligning ball bearing is a radial bearing with two rows of balls and a spherical raceway in the outer ring, which allows it to self-align and compensate for angular misalignment between shaft and housing. It is used in applications where shaft deflection or mounting errors are unavoidable. MR Accesorios Industriales sells these products in sizes from 10 mm bore diameter. Request a quote for your part number on WhatsApp.

The S series designation is read with the basic number followed by the letter S. For example, 1200S indicates a self-aligning bearing of the 1200 series with the S suffix, which in practice identifies the version with a steel sheet cage. The examples 1201S, 1202S, 1203S, 1204S, 1205S, 1206S and 1207S show how the size varies within the same series: the final number increases with the bore diameter. To request a quote, send us the complete part number exactly as it appears on your equipment.

These bearings are used in equipment where the shaft may deflect or where alignment between supports is not perfect. In Argentine industry they appear in belt conveyors, vibrating screens, textile machines, fans, centrifugal pumps and power transmission equipment in general. They are also chosen for mounting on long shafts, where thermal expansion or combined loads require the bearing to accommodate small angular movements without losing load capacity.

To correctly select a self-aligning bearing, take into account the radial and axial load it will support, the rotation speed and the type of lubrication. The S series accepts grease or oil lubrication; in dusty or humid environments, additional seals or protective covers should be evaluated. Mounting must be done with suitable tools, avoiding direct blows on the balls. Initial alignment is less critical than with rigid bearings, but it is always advisable to check internal clearance after mounting.

Regarding equivalents, self-aligning ball bearings are interchangeable between manufacturers while keeping the basic number and the suffix that indicates the design. An NTN 1205S can be replaced by an equivalent bearing from another brand that respects the same dimensions and tolerances.

The NTN SK series self-aligning ball bearing is a self-aligning bearing with two rows of balls, designed to carry radial loads and compensate for angular misalignment between shaft and housing. Its spherical outer raceway allows the inner ring to oscillate, absorbing mounting errors or shaft deflection. It is used in equipment where perfect alignment is not guaranteed, such as fans, pumps, conveyors and agricultural machinery. MR Accesorios Industriales sells the NTN SK series in Buenos Aires, Argentina, with more than 80 years of experience in bearings and power transmission.

The SK series designation is read simply: the basic number indicates the size and load capacity, and the SK suffix indicates that the bearing has a tapered bore with 1:12 taper. For example, 1204SK, 1205SK and 1206SK share the SK suffix, which allows it to be mounted directly on tapered shafts or with adapter sleeves. The higher the basic number, the larger the bore diameter and load capacity. This nomenclature makes it easy to quickly identify the series and its application.

In Argentine industry, SK series self-aligning bearings are found in industrial fans, centrifugal pumps, belt conveyors, vibrating screens and agricultural equipment. Their self-aligning capability makes them suitable for long shafts subject to deflection or for assemblies where the housing is not perfectly machined. They are also used in textile machines, industrial washing equipment and process equipment where alignment conditions vary. MR Accesorios Industriales sells them for replacement and new projects throughout the country.

To select an SK bearing, take into account the radial and axial load, the rotation speed and the type of sealing required. The tapered bore with 1:12 taper requires mounting on a tapered shaft or with an adapter sleeve; check the tightening torque and concentricity. Lubrication can be with grease or oil depending on the application, and the internal clearance is adjusted during mounting. Initial alignment is less critical thanks to the self-aligning capability, but it is advisable to check that the misalignment angle does not exceed the permissible limits. For dusty or humid environments, choose variants with seals or protective covers.

NTN SK series self-aligning bearings are interchangeable with those of other brands that follow the same dimensional nomenclature and the SK suffix. When replacing, compare the main dimensions, the bore type and the internal clearance. If the original part number corresponds to another brand, MR can tell you the compatible equivalent.

MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina, with more than 80 years of experience in bearings and power transmission.

The designation of these NTN spherical roller thrust bearings is interpreted from the series and the number indicating the size. For example, in 29230 the prefix 292 corresponds to a series of low-profile spherical roller thrust bearings, while the number 30 indicates the bore diameter in millimeters. In 293/500, the prefix 293 identifies a series with higher axial capacity and the number 500 indicates a bore diameter of 500 mm. The 294 series, as in 294/500, is used for higher axial loads. Learn more about these series and their applications by consulting MR.

These bearings are used in industries that handle large axial loads and require some tolerance to misalignment. In Argentina, they are common in applications such as rolling mill tables, port cranes, cement mills, presses and mining equipment. They also appear in paper machines and in some types of large gearboxes. Their ability to withstand axial loads in one direction makes them suitable for assemblies where the load acts mainly in one direction, such as support columns or vertical shafts.

To correctly select a spherical roller thrust bearing, take into account the magnitude and direction of the axial load, as well as the rotational speed. It is important to verify the alignment between the shaft and the housing, since although these bearings allow some misalignment, incorrect mounting can reduce their service life. Proper lubrication, whether with grease or oil, is essential to dissipate heat and protect the rolling surfaces. During mounting, ensure uniform support on the seating washers and avoid impacts that could damage the rollers or raceways.

Regarding equivalences and interchangeability, NTN spherical roller thrust bearings can replace those of other brands that follow the same standardized dimensions. If you need to replace a bearing from another brand, the safest approach is to compare the main dimensions (bore diameter, outer diameter and height) and the load capacities. MR Accesorios Industriales can advise you to find the NTN bearing equivalent to your current part number. Remember that interchangeability between brands is not always direct and depends on tolerances and internal design.

The double row angular contact ball bearing is a component designed to support radial and axial loads in both directions. Its construction with two rows of balls at opposing contact angles allows it to handle tilting moments, something a single row deep groove ball bearing cannot match. It is used in applications where precision and load capacity are critical, such as machine tool spindles, gearboxes and transmission equipment. MR Accesorios Industriales sells the NTN S series, with more than 80 years of experience in the Argentine market.

The NTN S series designation is read directly: the first digits indicate the size and the final letter S indicates the double row angular contact configuration. For example, the 5200S has a bore diameter of 10 mm, the 5201S of 12 mm, the 5202S of 15 mm, the 5203S of 17 mm, the 5204S of 20 mm, the 5205S of 25 mm, the 5206S of 30 mm and the 5207S of 35 mm. This nomenclature allows you to quickly identify the bore size and select the right bearing for your equipment.

In Argentine industry, these bearings are used in a wide variety of applications. They are found in machine tool main spindles, where rigidity and precision are essential. They are also found in gearboxes and gear cases that must withstand combined loads, in process centrifugal pumps, in compressors and in belt drive equipment. Their ability to handle axial loads in both directions makes them ideal for assemblies where the load direction changes during operation.

To correctly select an S series double row bearing, take into account the radial and axial load it will have to withstand, as well as the speed and lubrication conditions. It is essential to verify the correct internal clearance for your application: excessive clearance can generate vibrations and noise, while insufficient clearance can cause overheating. Mounting must be carried out with precise alignment between shaft and housing; any misalignment accelerates wear. Lubrication, whether with grease or oil, must be the one recommended by the manufacturer to ensure a long service life.

Regarding equivalences and interchangeability, double row angular contact bearings from different brands may differ in dimensions and load capacity. If you need to replace an existing bearing, the safest option is for you to send us the complete code engraved on the part or the main dimensions (bore, outer diameter and width).

It is used in industrial equipment, transmissions and machinery that demand a compact, high-performance bearing. MR Accesorios Industriales sells this series with the technical support you need to choose the right part number.

The SC series designation is read with the number indicating the size and the letters defining the sealing and configuration. For example, 5200SCZZ, 5201SCZZ and 5202SCZZ show the size number followed by SC and the ZZ suffix, which indicates metal shielding on both sides. As the number increases, the bearing size changes. The SC suffix identifies the double row angular contact series, and the final letters may vary depending on the type of closure. If you have any doubts, send us the complete part number and we'll quote it for you.

These bearings are used in industries such as food processing, metallurgy, textiles and plastics, in equipment such as pumps, compressors, fans, conveyor belts and machine tools. In Argentina, they are commonly found in production lines that need to withstand loads in two directions and maintain alignment. Their double row design allows replacing two single row bearings in a smaller space, simplifying equipment design.

To select the right bearing, take into account the radial and axial load it must withstand, the rotation speed and the environmental conditions. ZZ shielding protects against dust and moisture, but if there is contact with liquids or vapors, other closures should be evaluated. Mounting must be done with suitable tools, without striking the balls or raceways directly, and verifying shaft and housing alignment. Proper lubrication and internal clearance also affect service life.

NTN SC series bearings can be interchanged with those from other brands that follow the same dimensional nomenclature, such as SKF, FAG or NSK, as long as the main dimensions and sealing type match. It is important to verify the contact angle and load capacity, as they may vary between manufacturers.
