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 failure may include increased noise during operation or a slight increase in operating temperature. If left unaddressed, the bearing can seize, leading to shaft damage and potential loss of function in the affected system. Continued operation with a failing bearing risks significant downtime and costly repairs to related components.

Installation Tip

Ensure the bearing housing is thoroughly cleaned before installing the new bearing to prevent contamination. Avoid using excessive force or hammering on the bearing during installation, as this can damage the races and compromise its lifespan.

Service Note

Inspect the shaft for wear or damage and clean the bearing bore thoroughly before installing the new bearing.
