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

Early indications of failure include a low humming noise that escalates to a distinct grinding sound under load. Performance may degrade with noticeable sluggishness or increased heat generation around the axle. Prolonged operation risks axle shaft damage and potential loss of drive.

Installation Tip

Ensure the mounting surface and shaft are perfectly clean and free of burrs before attempting installation. Never use a hammer or pry bar directly on the bearing's rolling elements or seals during fitting.

Service Note

Inspect the axle shaft, seals, and surrounding lubrication passages for any signs of wear, damage, or contamination when replacing this bearing.
