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 failure may include a grinding noise during operation or increased heat around the component. If left unaddressed, the bearing can seize, leading to component seizure and potential damage to surrounding parts. Continued operation with a failing bearing risks significant 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 improper tools when pressing the bearing into its seat, as this can damage the races.

Service Note

Inspect adjacent seals and shafts for wear or damage when replacing this bearing.
