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 a grinding noise during operation or increased heat around the component. If left unaddressed, the bearing can seize, leading to shaft damage and potential operational shutdown. Continued operation with a failing bearing risks severe damage to connected components.

Installation Tip

Ensure the bearing housing is thoroughly cleaned of all old grease and debris before installation. Avoid using excessive force or hammering directly on the bearing races when pressing it into place.

Service Note

Inspect the shaft and housing for any signs of wear or damage that may have contributed to the bearing failure.
