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

Increased operational noise, such as grinding or whining, and noticeable vibration in the component or machine are early indicators. If left unaddressed, the bearing may seize, leading to shaft damage or complete stoppage of the affected system. This can result in loss of equipment function or damage to related components.

Installation Tip

Ensure the shaft and the bearing housing are perfectly clean and free of any debris or old lubricant before installation. Avoid applying excessive force when pressing the bearing into its housing.

Service Note

Inspect the shaft for any scoring or uneven wear, and replace any seals or gaskets associated with the bearing assembly.
