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 heat from the affected component. If ignored, the bearing can seize, leading to significant operational resistance and potential damage to surrounding components. Continued operation risks severe mechanical damage 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 the shaft or bore for any scoring or wear that could compromise the new bearing's performance.
