Single-Row Ball Bearing Design: The 304E typically utilizes a single-row ball-type slewing bearing. This design is optimized for the load conditions (primarily axial and moment loads) encountered by a machine of this size, providing an excellent balance of performance and compactness.
Integrated Gear Teeth: The bearing features precisely machined internal or external gear teeth that mesh perfectly with the pinion gear of the hydraulic swing motor. This ensures smooth, efficient, and precise power transfer for rotation.
This 175-1587 slewing bearing is used for 305.5 306 306E excavator.
