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 symptoms may include a faint grinding noise or increased vibration during operation, especially under load. If left unaddressed, the bearing will continue to degrade, potentially leading to excessive heat and seizure of the supported component. This could result in unexpected downtime and damage to related drivetrain parts.

Installation Tip

Ensure the bearing seat in the housing and on the shaft is perfectly clean and free of any burrs or debris before installation. Avoid using excessive force or hammering on the bearing during installation, as this can damage the internal components.

Service Note

Inspect the shaft and housing for wear or damage, and check associated seals when replacing this bearing.
