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

A failing bearing may initially produce a faint grinding noise or slight vibration during operation. As wear progresses, these noises will become more pronounced, and operational smoothness will decrease. Continued operation with a worn bearing can lead to increased heat generation and potential damage to adjacent components.

Installation Tip

Ensure the bearing housing is thoroughly cleaned before installation to prevent contamination. Avoid applying excessive force or using improper tools when pressing the bearing into its seat, as this can cause damage.

Service Note

Inspect seals and the surrounding component for wear or damage when replacing this bearing.
