CATBearing & Bushing

8X8654 Bearing — Cat 793

This is a heavy-duty roller bearing designed to support radial and axial loads within the power train or suspension system of large mining equipment. It is manufactured to meet stringent OEM material and dimensional tolerances, ensuring smooth rotation and load distribution unlike a worn bearing that can exhibit excessive play and noise. Operators may notice increased vibration, grinding sounds, or a noticeable looseness in the affected component when this bearing 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 failure may include a low humming or grinding noise that intensifies with load. If left unaddressed, the bearing will continue to degrade, leading to increased vibration and potential component misalignment. Continued operation with a failing bearing risks damage to surrounding drivetrain components.

Installation Tip

Ensure the bearing housing is thoroughly cleaned of all old grease and debris before installation. Avoid using excessive force or improper tools when pressing the bearing into its seat, as this can cause premature failure.

Service Note

Inspect and replace any associated seals and check adjacent shaft surfaces for wear or scoring.
