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 signs of failure may include unusual grinding noises or increased vibration during operation. If left unaddressed, the bearing can seize, leading to restricted movement or component seizure. Continued operation risks severe damage to adjacent components and potential equipment downtime.

Installation Tip

Ensure the bearing housing and shaft surfaces are meticulously clean before installation to prevent premature wear. Avoid using excessive force or improper tools when pressing the bearing into its seat, as this can cause deformation.

Service Note

Inspect the adjacent seals and lubrication system for any signs of contamination or leakage when replacing this bearing.
