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 may first present as an audible grinding or whining sound during operation. If ignored, this can escalate to severe vibration and reduced rotational speed of the affected component. Continued operation risks component seizure and potential damage to adjacent parts.

Installation Tip

Ensure the bearing bore is perfectly clean and free of any burrs or foreign material before attempting installation. Never use a hammer or pry bar to install the bearing; use a proper press or driver.

Service Note

Inspect the shaft and housing for any signs of wear or damage when replacing this bearing.
