The NSK spherical roller bearing is a component designed to withstand high radial loads and axial loads in both directions, with self-aligning capability. Its design with two rows of rollers and a spherical outer raceway compensates for angular misalignment between shaft and housing, which reduces precision requirements during mounting. It is used in industrial applications where there is shaft deflection, settling or heavy loads, such as transmissions, pumps, fans and mining equipment. MR Accesorios Industriales sells this line in Buenos Aires, Argentina.

The designation of the CE4 series is read from its numbers and suffixes. For example, 21319CE4 and 22326CE4 indicate the bearing type and its size; the CE4 suffix identifies a version with a brass cage and built-in lubrication, among other characteristics. The examples 23122CE4 and 23128CE4 correspond to higher-capacity series. Knowing the complete code is key to selecting the correct bearing for the application.

These bearings are used in Argentine industries such as steel, cement, mining, paper and food. They are present in conveyor belts, mills, crushers, centrifugal pumps, industrial fans and paper machines. Their ability to withstand combined loads and misalignment makes them suitable for equipment subject to vibration or shaft deflection, where other bearings would fail prematurely.

To select the right bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Sealing is essential: versions with seals protect against dust and moisture, while open ones require external lubrication. Internal clearance and lubrication must be specified according to the operating conditions. During mounting, ensure correct initial alignment and avoid impacts that could damage the rollers or the raceway.

Regarding equivalents, NSK spherical roller bearings can be interchanged with those of other brands that follow the same dimensional and design designation. If you have the code from another brand, we can indicate the equivalent NSK reference. Always verify tolerances and internal clearance before replacing, since small differences can affect performance.
