Single-row cross roller slewing bearing is composed of two seats, and features compact in structure, light in weight, small assembly space and high requirements to install. Rollers are 1: 1 cross-arrangement, making the bearings capable to bear axial force, overturning moment and considerable large radial force simultaneously. Single-row cross roller slewing bearing is widely used for lifting machinery, transportation, engineering machinery and military products.
