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

Initial signs of a failing bearing may include a faint grinding noise or increased vibration. If left unaddressed, the noise and vibration will intensify, potentially leading to premature wear on adjacent components. Continued operation with a severely damaged bearing can result in shaft damage or component seizure.

Installation Tip

Thoroughly clean the bearing bore and shaft to ensure a precise fit and prevent contamination. Avoid using excessive force or hammering on the bearing during installation, as this can cause internal damage.

Service Note

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