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 initial symptom of a failing bearing is often an audible whining or grinding noise that changes with load or speed. This can progress to noticeable vibration and increased heat in the affected area. Continued operation without replacement can lead to component seizure, causing significant operational disruption and potential damage to adjacent parts.

Installation Tip

Ensure the shaft and the bearing housing are perfectly clean and free from any burrs or imperfections before installation. Press the bearing in squarely and evenly to avoid damaging the races or the housing.

Service Note

Inspect the shaft or bore for wear, and check associated seals for integrity when replacing this bearing.
