Circuit

Machine movement can be fundamentally divided into rotary and linear motions. Ball bearings are among the most common 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 load carrying capability nad rigidity that ball bearings do not.

Cross roller rings are used in the rotary motion section of joints of arc welding robots used for mass production. Because cross roller rings are rigid in all directions of load and moments, they can be used in the compact robotic joints.
