In *22230CAME4 and *22232CAME4 the pattern repeats: the base number defines the diameter and width, while the final letters specify characteristics such as cage type and internal clearance. Knowing these suffixes is key to ordering the exact replacement.

These bearings are used in Argentine industries such as cement, mining, steel, paper and food. They are present in conveyor belts, ball mills, crushers, centrifugal pumps, industrial fans and paper machines. Their ability to withstand misalignment makes them ideal for equipment subject to vibration or deflection, where other bearings would fail prematurely. In pulp plants, for example, they are used in dryers and presses, while in mining they are mounted on screens and mills.

To select correctly, take into account radial and axial load, rotation speed and environmental conditions. Sealing is essential: in dusty or humid environments, choose variants with seals or protective plates. Lubrication must be adequate: high-viscosity grease for high temperatures or circulating oil in critical applications. Mounting requires initial alignment and a fit that allows self-alignment; avoid striking the rings. Internal clearance must be the specified one to compensate for thermal expansion.

Equivalences between brands are possible if dimensions and load capacity are compared. An NSK bearing can be replaced by one from another brand with the same basic designation, but check the suffixes, as they may vary the clearance, cage or heat treatment.

NSK spherical roller bearings are self-aligning, double-row components designed to withstand high radial loads and axial loads in both directions. Their spherical outer raceway allows the inner ring and rollers to self-align, compensating for angular misalignment between shaft and housing. They are used in equipment with shaft deflection or mountings that are difficult to align precisely, such as conveyors, mills, pumps and process machinery. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you on choosing the correct part number.

The CAMKE series designation is read in parts. The letters CAM indicate that the bearing has a machined brass cage, inner ring guided, and the letters KE indicate a tapered bore with 1:12 taper. The number following the prefix identifies the size: for example, 22228CAMKE4 and 22230CAMKE4 correspond to the 222 series, while 21319CAMKE4 and 21320CAMKE4 belong to the 213 series. The suffix E4 refers to a lubrication groove and holes in the outer ring, which make relubrication easier. Knowing these keys allows you to order the exact part number your equipment needs.

In Argentine industry, these bearings are found in applications where the shaft deflects or the mounting is not perfectly aligned. They are common in belt conveyors, hammer mills, high-flow centrifugal pumps, industrial fans, pulp and paper machines, and mining equipment. They also appear in gearboxes and in support rollers of rotary kilns. Their ability to operate with misalignment makes them suitable for mountings on long shafts or structures subject to vibration, where a rigid bearing would fail prematurely.

To select the correct bearing, take into account the radial and axial load, the rotation speed and the type of mounting. The tapered bore with 1:12 taper requires an adapter sleeve or a shaft with an equivalent taper; the tightening is controlled by measuring the reduction of internal clearance. Lubrication can be grease or oil, and the E4 suffix allows relubrication without disassembly. The machined brass cage is suitable for high speeds and moderate temperatures. Check the initial alignment and the residual clearance after mounting to avoid overloads.

When looking for equivalents, bear in mind that each manufacturer uses its own suffixes to indicate cage, taper and lubrication. A spherical roller bearing from another brand with a tapered bore and brass cage may be interchangeable, but always compare main dimensions, internal clearance and cage type. Do not rely only on the series number: suffixes change the behavior. If you have another brand's part number or an unidentified part, send us the data and at MR Accesorios Industriales we will indicate the compatible alternative.

It is used in applications where precision and rigidity must be combined, such as machine tool spindles, pumps and gearboxes. At MR Accesorios Industriales we quote it on WhatsApp.

The A series designation is read together with the bore diameter number and the suffix that indicates the contact angle. For example, 7003 A, 7004 A and 7005 A correspond to single row bearings with a 30° contact angle. The final number (03, 04, 05) is related to the bore diameter: the higher the number, the larger the diameter. The letter A indicates the standard contact angle of the series. Other suffixes may indicate a polyamide cage, internal clearance or precision, but it is always advisable to confirm the complete part number when requesting a quote.

These bearings are used in industries such as metalworking, food, chemical and petrochemical. In Argentina they are commonly found in lathe and milling machine spindles, centrifugal pumps, screw compressors and speed reducers. They are also used in power transmission equipment where high rigidity and rotational precision are required, such as machine tools and measuring equipment. Their ability to support combined loads makes them suitable for tandem or paired arrangements.

To select the correct bearing, the axial and radial load, the rotational speed and the environmental conditions must be taken into account. Sealing is a key factor: if there is dust or moisture, variants with seals or shields should be chosen. Lubrication must be suitable for the temperature and speed; in high-precision applications low-friction grease is usually used. Mounting requires careful alignment and, in many cases, preload adjustment to eliminate axial clearance. It is important to follow the manufacturer's recommendations for tightening torque and internal clearance.

As for equivalents, angular contact bearings from other brands with similar designations may be interchangeable, but the dimensions and contact angle must be verified. For example, an SKF 7005 ACD/P4A bearing may replace an NSK 7005 A if the tolerances and clearance match. However, not all suffixes are equivalent: the final letters may indicate differences in cage, angle or precision.

Double row angular contact ball bearings

See the 69 products →

NSK double row bearings

The double row angular contact ball bearing is a component designed to withstand combined radial and axial loads in both directions. Its two-row ball construction allows it to absorb tilting moments, which is why it is used in applications where rigidity and precision are important. MR Accesorios Industriales sells the NSK line for industrial equipment in Buenos Aires, Argentina.

The designation of these NSK bearings is based on a four-digit number that starts with 52, as in the examples 5200, 5201, 5202 or 5207. The first two digits identify the double row series, and the next two indicate the size, which increases in steps. Each part number refers to a specific combination of dimensions and load capacity. To select the correct bearing, the most practical approach is to start from the complete part number shown on the equipment or on the drawing.

These bearings are used in a wide variety of industries in Argentina. They appear in centrifugal pumps, compressors, industrial fans, machine tools and transmission equipment. They are also present in applications where axial loads must be supported in both directions, such as milling machine spindles or conveyor rollers. Their double row makes them suitable for assemblies that must withstand tilting moments, for example in overhung shaft supports.

To choose the right bearing, take into account the type of sealing: there are open versions, versions with shields or with contact seals, which defines protection against contaminants and lubricant retention. Lubrication can be with grease or oil, depending on the operating speed and temperature. Installation requires correctly aligning the supports and applying the preload or axial clearance recommended by the manufacturer. Poor alignment accelerates wear on the balls and raceways.

As for equivalents, double row angular contact bearings from different brands can be interchanged if the main dimensions and tolerances match. NSK, SKF, FAG, NTN and other companies offer products with similar characteristics. If you have the part number from another brand, we can help you identify the equivalent NSK reference. It is always advisable to verify the complete designation and technical specifications before replacing a bearing.

If you need a bearing from this series, write to us on WhatsApp with the part number or the measurements of the equipment. At MR Accesorios Industriales we will quote the exact reference you are looking for and get back to you shortly. We can also advise you if you have doubts about the designation or the type of sealing that best suits your application.

NSK double row angular contact bearings …AZZ

NSK AZZ series double row angular contact ball bearings are components designed to support combined radial and axial loads in both directions. Their two-row ball construction allows greater load capacity than a single row bearing in the same space. They are used in applications requiring rigidity and precision, such as machine tools, pumps and industrial equipment. MR Accesorios Industriales sells this line in Buenos Aires, Argentina.

The AZZ series designation is interpreted as follows: the initial number (for example, 5203, 5302) indicates the size and dimension series; the AZZ suffix indicates sealing or internal clearance characteristics. In the examples 5203AZZ, 5204AZZ, 5207AZZ, 5208AZZ, 5210AZZ, 5211AZZ, 5302AZZ and 5303AZZ, the digits 52 and 53 correspond to double row series with different section. The AZZ suffix usually indicates a specific seal; to confirm the exact meaning, we provide the technical data sheet when you request a quote.

These bearings are used in industries such as food, chemical, petrochemical and manufacturing. In Argentina, they are commonly found in centrifugal pumps, compressors, industrial fans, machine tools and transmission equipment. Their ability to support axial loads in both directions makes them suitable for spindles and shafts where high rigidity is required. They are also used in applications with moderate speeds and high precision requirements.

To select the correct bearing, take into account the radial and axial load it must support, the rotation speed and the environmental conditions. The AZZ seal protects against contaminants and retains lubricant, but verify compatibility with the environment. Mounting requires precise alignment and adequate lubrication; in double row, the internal clearance is already defined at the factory, so it is not adjusted. Follow the manufacturer's recommendations for tightening and cleanliness.

Regarding equivalents, double row angular contact bearings from other brands can be interchanged if dimensions and load capacity match. If you have the part number from another brand, we will indicate the compatible alternative. MR Accesorios Industriales sells the NSK brand and can advise you on interchangeability. It is always advisable to verify tolerances and internal clearance before replacing.

To request a quote, send us the exact part number you need via WhatsApp, for example 5203AZZ or 5302AZZ. We respond promptly with availability and conditions. If you are looking for a variant you do not see, write to us with the model and we will quote it. At MR Accesorios Industriales we have more than 80 years of experience in bearings and power transmission, and we are in Buenos Aires, Argentina, to advise you.

NSK double row ADDU bearings

The double row angular contact ball bearing is a component designed to support combined radial and axial loads in both directions. Its two-row ball construction allows higher load capacity than a single row bearing in the same space. It is used in applications requiring rigidity and precision, such as machine tools, pumps and gearboxes. MR Accesorios Industriales sells the NSK ADDU series, with more than 80 years of experience in the Argentine industrial market.

The ADDU series designation is interpreted from its examples: 5203ADDU, 5204ADDU, 5207ADDU, 5208ADDU, 5210ADDU, 5211ADDU, 5302ADDU and 5303ADDU. The first digits indicate the size and dimension series; the ADDU suffix indicates sealing and internal clearance characteristics. In these bearings, the double row of angular contact balls allows axial loads to be supported in both directions, making them suitable for assemblies requiring high axial rigidity.

In Argentine industry, these bearings are found in machine tool spindles, centrifugal pumps, compressors, gearboxes and power transmission equipment. They are also used in applications where axial and radial clearance must be controlled precisely, such as milling heads or rolling mill rolls. Their capacity for combined loads makes them versatile in sectors such as metalworking, food and petrochemical.

To select the right bearing, take into account the radial and axial load it must support, the rotation speed and the environmental conditions. The ADDU seal protects against the entry of contaminants and lubricant loss, so it is important to verify compatibility with the type of lubrication. During assembly, ensure correct alignment and avoid impacts that could damage the raceways. Proper lubrication and correct internal clearance are key to long-lasting performance.
