SKF 22324 CCKJA/W33VA405 SPHERICAL ROLLER BEARING

Self-aligning roller bearings play a key role in the proper functioning of equipment subjected to high mechanical loads. Their robust design ensures reliable and continuous performance, even under unstable or demanding operating conditions.

This SKF spherical roller bearing is designed to withstand high loads, even in the event of shaft misalignment. Thanks to its self-aligning capability and two rows of rollers, it accommodates both radial and axial loads. This CC-type bearing is open and features an annular groove and three lubrication holes on the outer ring (W33), facilitating relubrication. It is specifically designed for machines subject to vibration.

Features:
This self-aligning bearing features a 1:12 tapered bore, which facilitates precise mounting on the shaft and allows the internal clearance to be adjusted according to the application’s requirements. Designed for machines subject to high levels of vibration, it withstands very high loads, speeds, accelerations, and centrifugal forces. Its CC design incorporates two stamped steel window cages, surface-hardened to improve wear resistance, a shoulderless inner ring, and a floating guide ring centered on the inner ring. This architecture enables better load distribution, stable roller guidance, reduced internal stresses, and smoother operation at high speeds. The C4-type internal radial clearance improves resistance to thermal expansion and high speeds. Its robust structure reduces vibrations and promotes a longer service life, even in demanding industrial environments.

Maintenance:
Since this bearing is open, it facilitates visual inspection and maintenance operations but requires regular relubrication, particularly in dusty or humid environments. Not pre-lubricated, this bearing is compatible with various types of grease depending on operating conditions, including high temperatures up to 200°C. It features an annular groove and three lubrication holes on the outer ring, which ensure even lubricant distribution, facilitate the removal of contaminants, and extend the bearing’s service life. Regular monitoring of noise levels and temperature can help anticipate maintenance needs.

Sealing:
This bearing is an open-type bearing with no built-in seals. This design reduces internal friction but also makes it more vulnerable to contaminants and moisture. To compensate for this weakness, its annular groove and three lubrication holes on the outer ring facilitate lubricant distribution, the removal of contaminants, and the maintenance of a protective layer of grease.
