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

An audible grinding or squealing noise from the affected machine area is often the first indication of bearing failure. As the wear progresses, increased friction may lead to sluggish movement or binding in the component. Continued operation without replacement can result in component seizure or damage to adjacent parts.

Installation Tip

Thoroughly clean the bearing housing and shaft surfaces before pressing in the new bearing to ensure proper seating. Do not use excessive force or impact tools that could damage the bearing races.

Service Note

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