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 bearing housing. 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 damage to adjacent components.

Installation Tip

Ensure the bearing housing is thoroughly cleaned before installing the new bearing to prevent premature wear. Avoid using excessive force or improper tools when seating the bearing, as this can cause damage.

Service Note

Inspect the shaft for any signs of wear or damage and check the surrounding seals for integrity when replacing this bearing.
