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 failure include unusual noises during operation or a slight increase in operating temperature. If ignored, the bearing can seize, leading to severe damage to the shaft and surrounding components. Continued operation risks significant mechanical failure and extended equipment downtime.

Installation Tip

Confirm that the bearing seat is perfectly clean and free from any debris or old lubricant before pressing the new bearing into place. Avoid applying any side load or forcing the bearing during installation, as this can damage the internal components.

Service Note

Inspect the shaft for any signs of scoring or wear, and ensure the bearing housing is clean and free of contaminants.
