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 faint grinding noise during operation. If left unaddressed, the noise will intensify, and excessive play may develop in the supported shaft. Continued operation with a failing bearing risks damage to adjacent components and potential operational downtime.

Installation Tip

Ensure the bearing seat is clean and free of debris before installation, as even small particles can cause premature wear. Avoid using excessive force or hammering directly on the bearing during installation; use appropriate bearing drivers.

Service Note

Inspect the shaft and housing for any signs of wear or damage when replacing this bearing.
