Подшипник поворота Caterpillar 2168922

The Swing Bearing is a large-diameter rotational bearing used to facilitate the 360-degree rotation of the upper frame relative to the undercarriage in tracked equipment. It supports the combined axial (vertical), radial (horizontal), and moment (tilting) loads generated during slewing, lifting, and digging activities. Constructed from hardened alloy steel, the slewing bearing consists of inner and outer race rings with a series of rolling elements, either balls or rollers, arranged in one or more raceways. The bearing is gear-integrated to mesh directly with the swing drive pinion, enabling torque transmission from the swing motor.Attributes:• Maintains structural alignment during swing.• Preloaded to reduce deflection under tilt.• Compatible with centralized lubrication systems.Applications: The Swing Bearing is located between the upper structure and undercarriage, forming the rotational joint that supports and enables swing movement in tracked equipment.
