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 a failing bearing include unusual noises such as grinding or knocking, and increased vibration. If left unaddressed, the bearing can seize, leading to shaft damage and potential operational shutdown. Continued operation with a compromised bearing risks significant damage to adjacent components.

Installation Tip

Ensure the bearing seat in the housing is perfectly clean and free of debris before installation. Avoid using excessive force or hammering on the bearing during installation, as this can damage the delicate internal components.

Service Note

Inspect the shaft for scoring or wear, and clean the bearing bore thoroughly before installing the new bearing.
