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

Early indications of bearing failure include a low humming or rumbling sound that grows louder with increased load. If ignored, the noise will escalate, potentially accompanied by excessive heat and vibration, leading to reduced power transmission. Continued operation risks severe damage to the shaft and housing.

Installation Tip

Ensure the shaft and housing surfaces are perfectly clean and free of any burrs or debris before attempting installation. Never use a press that contacts the inner ring only, as this can damage the bearing cage.

Service Note

Check the condition of the drive shaft and mating components for any signs of wear or scoring during replacement.
