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 include audible grinding or humming noises during operation. If left unaddressed, the noise will intensify, and excessive heat may develop around the component. Continued operation risks component seizure and potential damage to surrounding parts.

Installation Tip

Ensure the bearing housing is meticulously clean before installing the new bearing to prevent premature 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 and housing for wear or damage, and clean the mounting area thoroughly before installing the new bearing.
