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

A failing bearing often begins with an audible humming or grinding sound that increases with speed. This can progress to noticeable vibration in the machine's chassis or drivetrain. Continued operation with a worn bearing risks catastrophic failure of the associated axle or transmission components.

Installation Tip

Ensure the bearing seat in the housing is perfectly clean and free of any debris or old lubricant residue. Press the bearing in squarely and avoid cocking it, which can damage the races and lead to premature failure.

Service Note

Inspect the shaft, seals, and surrounding components for wear or damage when replacing this bearing.
