Types of THK Cross-Roller Ring/ Double Row Ring

Cross-Roller Ring

Double Row Angular Contact Ring

High-Speed Roller Ring

With the Cross-Roller Ring, cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90° V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including radial, axial and moment loads. High rigidity and high precision are realized by increasing the number of rollers through the use of double rows.
High rigidity and wobbling accuracy specifications make it ideal for rotating mechanisms of multitasking machines.
THK roller rings are used in the machine tool, robotics, and various other industries. THK has concentrated the know-how it has built in the course of this to develop the High-Speed Roller Ring RT for high-speed rotary performance.
