The single-row crossed roller slewing bearing is composed of 2 seat-rings, characterized by its compact in design, light in weight, strict ptoducing accuracy, small fabrication gap abd high requirements for mounting accuracy. The rollers are arranged in cross 1: 1. This kind of bearing is able to bear axial loads, overturning torque, and relatively high radial loads.
The crossed cylindrical roller slewing ring has relatively higher static capacity. The crossed tapered roller slewing bearing have heavier rigidity and higher running accuracy because of its pre-interference.
It widely used in elevating machinery, harbor machinery, mining machinery, constructional engineering machinery, missile launcher and other large-sized rotators.
