CATBearing & Bushing

8J0001 Bearing — Cat 515 518

This bearing is a fundamental component designed to reduce friction between moving parts, typically found in rotating assemblies like wheel hubs or transmission shafts. It allows for smooth, low-resistance motion, unlike a worn bearing that will generate heat and noise. Operators will often hear a grinding or humming noise that increases with speed, and may feel excessive play or looseness in the affected component.

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

The first indication of a failing bearing is often an audible humming or grinding noise that intensifies with the speed of rotation. If ignored, the bearing will continue to degrade, leading to increased friction, heat generation, and potential seizure of the rotating component. Continued operation with a failed bearing can cause significant damage to the shaft, housing, and surrounding drivetrain parts.

Installation Tip

Ensure the bearing bore and shaft are clean and free of burrs before installation; do not use excessive force to press the bearing, as this can damage the races.

Service Note

Inspect the shaft and housing for wear or damage when replacing the bearing.
