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 failure signs include audible grinding or whining sounds and noticeable vibration during operation. If the bearing continues to operate in a degraded state, it can lead to component seizure and potential damage to shafts and housings. The ultimate risk is the loss of power transmission or complete component failure, halting equipment function.

Installation Tip

Ensure the bearing bore and shaft are perfectly clean and free from any contaminants before installation. Avoid pressing the bearing onto the shaft using force applied to the outer race; use a proper bearing installer.

Service Note

Inspect the shaft and housing for wear, and check the condition of seals and lubrication passages associated with the bearing.
