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 faint grinding noise during operation or slight play in the component it supports. If left unaddressed, the noise will intensify, and excessive wear can lead to component seizure. Continued operation with a failing bearing risks damage to adjacent components and potential operational downtime.

Installation Tip

Ensure the bearing housing is meticulously clean before installation to prevent contamination. Avoid using excessive force or hammering the bearing into place, as this can cause internal damage.

Service Note

Inspect the shaft and housing for any signs of wear or scoring that may necessitate replacement.
