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 include a noticeable increase in play in the upper structure, audible clicking or grinding noises during swings, and potentially jerky rotation. If ignored, the bearing can seize, preventing the upper structure from rotating, leading to significant operational disruption and potential damage to the swing motor and gears.

Installation Tip

Thoroughly clean the mounting surfaces on both the undercarriage and the upper structure before installing the new bearing. Ensure all mounting bolts are tightened in a star pattern to evenly distribute stress.

Service Note

When replacing the swing bearing, inspect the swing motor, gears, and lubrication system for any signs of wear or contamination.
