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.

If you need an NSK spherical roller bearing for your equipment, write to us on WhatsApp with the part number or the shaft and housing dimensions. We will quote you promptly and help you define the appropriate mounting and lubrication. We work with the NSK line and other brands so that you find the part your machine needs.
