Single-row crossed roller slewing bearings (external gears)

Single-row crossed roller slewing bearings (external gears)

Single row cross cylindrical roller slewing bearing consists of two races. It is compact in structure, light in weight, high in manufacturing precision and small in assembling clearance with high requirements for installation accuracy, and has 1:1 cross-arrangement of rollers. It can withstand axial force, tilting moment and large radial force at the same time, and is widely used in hoisting and conveying, construction machinery and military products.
