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

The initial symptom of a failing bearing is often an abnormal noise, such as grinding or squealing, originating from the affected component. As wear progresses, increased vibration and reduced operational efficiency of the system will become apparent. Continued operation can lead to component seizure or damage to adjacent parts.

Installation Tip

Ensure the housing and shaft surfaces are perfectly clean and free of burrs before attempting installation. Never use excessive force or hammer the bearing into place, as this can cause immediate damage.

Service Note

Inspect the shaft or bore for any signs of wear or damage that may have contributed to the bearing failure.
