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 resistance when turning a component. If left unaddressed, the bearing can seize, leading to component damage and potential loss of mobility. Continued operation with a failing bearing risks severe damage to associated shafts and housings.

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 or rollers.

Service Note

Inspect the associated shaft and housing for any signs of wear or damage, and ensure proper lubrication is applied.
