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 generation around the component. If left unaddressed, the bearing can seize, leading to restricted movement or potential damage to adjacent components. 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 cause damage.

Service Note

Inspect the surrounding shaft and housing for any signs of scoring or wear that may affect the new bearing's performance.
