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 failure may present as a low rumbling noise or slight vibration during operation. If ignored, the bearing can seize, potentially damaging the shaft and housing, and leading to significant operational disruption. Continued use risks severe mechanical damage and extended equipment downtime.

Installation Tip

Carefully inspect the shaft and housing for any burrs or damage before installing the new bearing. Ensure the bearing is pressed on squarely and evenly to avoid damaging the raceways.

Service Note

Check the condition of the seals and the lubricant for any signs of contamination or wear when replacing this bearing.
