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 faint grinding noise or increased vibration during operation. If left unaddressed, the bearing can seize, leading to component seizure and potential damage to surrounding parts. 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 the bearing into place, as this can damage the races or cage.

Service Note

Inspect the shaft and housing for wear or damage, and consider replacing seals if applicable.
