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 low humming or grinding noise that increases with speed is often the first sign of bearing wear. As the wear progresses, vibration may become noticeable, and the component may feel stiff or difficult to turn. Continued use risks damage to the shaft or housing and potential failure of the entire component.

Installation Tip

Carefully inspect the bearing seat and shaft for any imperfections or contamination before installation. Ensure the bearing is seated perfectly square to prevent damage to the inner or outer races.

Service Note

Inspect the shaft or bore for wear and ensure proper lubrication is applied during installation.
