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 increased noise during operation, such as humming or grinding. If left unaddressed, the bearing will continue to degrade, leading to excessive heat and potential component seizure. Continued operation with a failing bearing risks severe damage to the supported shaft and surrounding components.

Installation Tip

Ensure the bearing housing is thoroughly cleaned of all old grease and debris before installation. Avoid using excessive force or hammering directly on the bearing races during installation, as this can cause internal damage.

Service Note

Inspect the shaft and housing for any signs of wear or scoring that may have contributed to the bearing failure.
