High-Precision 9245698 Slewing Ring Bearing for Upper Structure Rotation – Compatible with Hitachi ZAX330-3 / ZX330-5G / ZX350-3 / ZX400L-5G Excavators.

Lubrication Management:
Proper and regular lubrication is essential for reliable slewing bearing performance. Using incorrect grease, insufficient replenishment, or extended intervals can lead to poor lubrication, increased friction, and accelerated wear. Always select grease based on bearing type and working conditions, and follow recommended lubrication schedules.

Inspection & Servicing:
Periodically inspect the bearing for wear, cracks, abnormal noise, clearance changes, and bolt tightness. Early detection and correction of issues help prevent severe damage and extend service life.
