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 a grinding noise during operation or increased heat from the component. If left unaddressed, the bearing can seize, leading to shaft damage and potential operational downtime. Continued operation with a failing bearing risks severe damage to adjacent components.

Installation Tip

Ensure the bearing housing is thoroughly cleaned before installation to prevent contamination. Avoid using excessive force or hammering directly on the bearing during installation, as this can cause internal damage.

Service Note

Inspect the shaft for wear or damage and check associated seals for integrity when replacing this bearing.
