Slewing (Swinging) Motion:
It enables the 360-degree continuous rotation of the upper structure. This is essential for the excavator's efficiency, allowing it to dig in one location and dump the material in another without moving the tracks.
Power Transmission:
The slewing bearing's internal gear teeth mesh with the pinion gear of the swing motor and reduction gear. This transfers the hydraulic power from the swing motor into a smooth, controlled rotational movement.
This 205-9913 slewing bearing is used for M315D2 M313D excavator.
