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 inner bearing may include a grinding noise during operation or increased play in the wheel. If left unaddressed, the bearing can seize, leading to wheel lock-up and potential damage to the axle or hub assembly. This can result in unexpected downtime and costly repairs.

Installation Tip

Ensure the bearing housing is thoroughly cleaned of all old grease and debris before installation. Avoid using excessive force or hammering directly on the bearing races when pressing it into place.

Service Note

Inspect the wheel hub, spindle, and axle for any signs of wear or damage when replacing the inner bearing.
