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 first present as a subtle humming or increased vibration during operation. If ignored, this can escalate to noticeable binding or a rough operational feel. Continued use risks damage to the connected components and potential operational downtime.

Installation Tip

Ensure the mounting surfaces are perfectly clean and free of debris before seating the bearing. Never use a hammer or pry bar directly on the bearing itself during installation; use appropriate pressing tools.

Service Note

Check the condition of the shaft and housing where the bearing mounts for any signs of wear or scoring.
