External Gear Slewing Bearing Use For Gantry Crane
Ball Slewing Bearing is composed of 2 seat rings.It features compact in design,and light in weight.The balls contact with the circular race at four points,via which the axial force,radial force and resultant moment may be born simultaneously.
The four-point-contact ball bearing is a single row angular contact bearings designed to handle two-directional axial loading. These bearings require a minimum amount of space and can be custom designed to meet our customer's unique loading parameters. And the four-point-contact ball bearings can carry either pure axial loading or combined loading provided the axial component is more significant.
For heavy industrial requirements, this style of bearing can be designed as a large slewing ring bearing with bolted down races and internal or external integral gearing.
