Integrated Gear Ring: The bearing features an internal or external gear ring that meshes with the pinion gear of the hydraulic swing motor. This direct integration transmits the rotational force from the motor to the upper structure.
High Load-Carrying Capacity: Specifically engineered to manage the significant axial, radial, and moment loads typical of a 30-40 ton class excavator, ensuring structural integrity and safe operation.
Sealing and Protection: High-performance seal systems are integrated to protect the internal rolling elements and raceways from abrasive contaminants like dust, dirt, and moisture, which are prevalent on construction sites. This is crucial for long service life.
This 7Y-0935 slewing bearing is used for 330 excavator.
