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 may include a subtle humming sound that intensifies with speed. If left unaddressed, the bearing can seize, causing significant friction and potential damage to the shaft and surrounding components. Continued operation risks extended equipment downtime.

Installation Tip

Ensure the shaft and bearing bore are perfectly clean and free from any debris or old lubricant residue. Never use a hammer to drive the bearing into place; use a proper press or driver tool.

Service Note

Inspect the shaft for any signs of wear or damage, and clean the bearing housing thoroughly before installing the new bearing.
