Enabled 360-Degree Rotation:
It provides a robust, low-friction rotational axis, allowing the entire upper structure to swing smoothly and continuously through a full 360 degrees under full load.
This unrestricted rotation is fundamental to the machine's cycle time and operational efficiency.
Power Transmission for High-Torque Swing:
The bearing features integrated, hardened gear teeth that mesh with the pinion gear of the high-torque hydraulic swing motor.
It efficiently transmits power from the swing motor to the upper structure, enabling precise and powerful control during rotation, even when swinging a fully loaded bucket.
This 367-8346 slewing bearing is used for 336D 330D 336D2 excavator.
