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 bearing failure is often an audible grinding or whining noise during operation. If left unaddressed, this noise will increase in intensity, accompanied by significant heat buildup around the component. Continued operation risks severe damage to the shaft and housing, potentially leading to component seizure.

Installation Tip

Ensure the bearing bore and shaft are meticulously clean before installation to prevent contamination. Avoid using excessive force or hammering on the bearing during installation, as this can damage the races and rollers.

Service Note

Inspect the shaft and housing for any scoring or wear, and check seals for damage or leakage.
