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 initially present as a subtle increase in operational noise or a slight vibration. If ignored, the noise will become more pronounced, and heat buildup can occur, potentially damaging the shaft or housing. Continued use risks significant mechanical stress and component failure.

Installation Tip

Ensure the shaft and bearing bore are perfectly clean and free from any burrs or imperfections prior to installation. Do not use a hammer or pry bar to seat the bearing; use a proper press or driver.

Service Note

Check the condition of the shaft and the bearing housing for any signs of scoring or wear during replacement.
