This is a CAT Self-Aligning Bearing, designed to accommodate minor shaft misalignment and reduce friction in rotating assemblies. It is manufactured to OEM standards, ensuring smooth operation and longevity, unlike a worn bearing that can cause excessive vibration and heat. Operators may hear grinding noises, feel excessive play in the shaft, or notice increased operating temperatures if this bearing is failing.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of a failing self-aligning bearing is often an audible noise, such as a grinding or squealing sound, during operation. If left unaddressed, the bearing can seize, causing severe damage to the shaft and housing, and potentially leading to a complete loss of function for the driven component. This can also generate excessive heat, posing a fire risk in some applications.
Ensure the shaft and housing surfaces are perfectly clean and free of burrs before installation. Never use a hammer to drive the bearing into place; use a proper press or bearing installation tool.
When replacing a self-aligning bearing, inspect the shaft for any signs of wear or scoring, and check the condition of any seals or related components.
