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

The first sign of a failing bearing is often an audible grinding or whining noise originating from the affected component. If left unaddressed, the noise will intensify, and the component may overheat, leading to reduced operational efficiency. Continued operation with a failing bearing risks damage to surrounding components and potential operational downtime.

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 premature failure.

Service Note

Inspect the shaft and housing for any signs of scoring or wear that could compromise the new bearing's performance and lifespan.
