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 signs of failure can include audible grinding or squealing sounds, and excessive play or looseness in the component. If neglected, the bearing can seize, leading to restricted movement or complete stoppage of the affected system. Continued operation risks severe damage to the mating components and significant operational downtime.

Installation Tip

Before installation, meticulously clean the bearing housing and the shaft to ensure a precise fit and prevent premature wear. Avoid applying any direct impact to the bearing's outer or inner race during fitting.

Service Note

Inspect the adjacent seals and shaft for any signs of wear or damage when replacing this bearing.
