1 Single-Row Crossed Roller Slewing Ring CHARACTERISTIC OF STRUCTURE,PERFORMANCE, AND APPLICATION The Single-Row Crossed Roller Slewing Ring is composed of two seat-rings. It features compact in design, light in weight, high in installing-precision and small in assembly-clearance. As the rollers are arranged across as 1:1 proportion, it is capable of undertaking Axial Force, Tipping Moment and rather large Radial Force at the same time. The single-row crossed roller slewing rings are widely used for hoisting and transporting machine, construction machinery as well as for military products.
