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 slight increase in operating temperature. If left unaddressed, the noise will intensify, and excessive heat can lead to component damage. Continued operation with a severely worn bearing risks shaft damage and potential seizure of rotating parts.

Installation Tip

Ensure the bearing housing is meticulously cleaned before installing the new bearing to prevent contamination. Avoid using excessive force or improper tools when pressing the bearing into its seat, as this can damage the races.

Service Note

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