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 from the component. If ignored, the bearing can seize, leading to component seizure and potential drivetrain damage. This could result in unexpected equipment downtime and costly repairs.

Installation Tip

Ensure the bearing housing is thoroughly cleaned before installation to prevent contamination. Avoid using excessive force or improper tools when pressing the bearing into its seat, as this can cause damage.

Service Note

Inspect the associated seals and lubrication system for wear or contamination when replacing this bearing.
