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 during operation or increased heat around the component. If left unaddressed, the bearing can seize, leading to severe damage to the supported shaft and surrounding components. Continued operation with a failing bearing risks significant 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 premature failure.

Service Note

Inspect the shaft and housing for wear or damage during replacement.
