Circuit

Machine movement can be fundamentally divided into rotary and linear motions. Ball bearings are among the most famous machine parts exhibiting rotary motion, but among THK's products, the representative rotary motion device would be our "Cross-Roller Rings". These devices offer an efficiency that ball bearings do not.

Cross-roller rings are used in the rotary motion section of joints of arc welding robots on a production line of factories. Because cross-roller rings alone are rigid in the direction of each load of radial and axial moments, they can be used to develop the compact joints of robots.
