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

A failing bearing may initially exhibit a subtle increase in noise, such as a whirring or grinding sound, especially under load. This can escalate to noticeable vibration and heat buildup. Continued operation risks the bearing seizing, potentially damaging associated components and hindering equipment operation.

Installation Tip

Always ensure the bearing is pressed in squarely to prevent cocking, which can lead to premature failure. Verify that the shaft and housing surfaces are clean and smooth before installation.

Service Note

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