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

Early indications of bearing failure include a grinding or humming noise during operation, which may worsen with speed. If left unaddressed, the noise will intensify, and the component may begin to bind or vibrate excessively. Continued use can lead to component seizure and potential damage to surrounding parts.

Installation Tip

Ensure the housing and shaft surfaces are perfectly clean and free from any burrs or imperfections before attempting installation. Never force the bearing into place; it should fit snugly but without excessive pressure.

Service Note

Inspect the shaft or mating component for wear and ensure the lubrication system is functioning correctly.
