External Gear Four-point Contact Ball Slewing Bearing | Precision Slewing Ring Bearings

Four-point Contact Ball Slewing Bearing (External Gear)

Four-point contact ball slewing bearings (external gear) are specialized bearings designed to handle high loads while providing precise rotational movement. The inclusion of an external gear allows for direct integration with a drive mechanism, making these bearings suitable for applications where power transmission and rotational control are critical. The bearing has four points of contact between the balls and the raceways, allowing it to support axial, radial, and tilting moment loads. This design ensures even load distribution and stability. An external gear is incorporated into the outer ring of the bearing. This gear allows the bearing to be driven directly by an external pinion, facilitating efficient power transmission. The integration of the external gear into the bearing’s outer ring helps reduce the overall size of the system while maintaining high load capacity.
