The 9166468 HITACHI EX330LC-5 Excavator slewing ring bearings primarily consist of an inner ring, an outer ring, rolling elements (steel balls or cylindrical rollers), spacers or a cage, sealing devices, and lubrication holes. Mounting holes are typically machined into the inner and outer rings, and some models feature internal or external gear teeth for meshing with a drive gear.
This bearing features a compact structure capable of simultaneously withstanding axial loads, radial loads, and tilting moments. It offers high rigidity and smooth rotation, while being easy to install and maintain. The gear ring design enables active rotary drive, and the sealing structure effectively prevents the ingress of dust and moisture, making it suitable for harsh operating conditions.
