5P8296 4B9374 — Cat 941 951b

This is a high-quality inner bearing race, a critical component of a wheel or final drive bearing assembly, designed to provide a smooth raceway for the bearing rollers. It is manufactured to precise tolerances, ensuring proper fit and function, unlike a worn race which would show pitting or scoring. Operators may observe increased noise from the affected axle or a noticeable looseness in the wheel when this component begins to fail.

Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial signs of a failing bearing race include increased humming or grinding noise from the wheel hub or final drive. If ignored, the bearing will likely seize or develop excessive play, leading to uneven tire wear or potential wheel detachment. Continued operation risks damage to the spindle or axle housing.

Installation Tip

Properly clean the bearing bore and shaft before attempting to press the new race into place. Ensure the race is seated perfectly square to prevent damage during installation.

Service Note

Always replace the corresponding outer race and the bearing rollers when servicing or replacing an inner bearing race.
