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 failure may manifest as a distinct whining or grinding sound during operation of the affected component. If ignored, the bearing can seize, leading to restricted movement and potential damage to the drive or swing mechanism. Continued use risks compromising the integrity of the entire drive or swing system.

Installation Tip

Before installing, verify that the bearing seat in the housing and the shaft are perfectly clean and free of burrs. Never use a hammer or pry bar to install the bearing; use a proper press or drift tool.

Service Note

Inspect the seals and any associated gears or drive components for wear or damage when replacing this bearing.
