Cross Roller Ring RU66

Detailed introduction to RU66 crossed roller bearing THK high precision bearing:
 

With the Cross-Roller Ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90V 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. Since the Cross-Roller Ring achieves high rigidity despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines.  

RU series(Integrated Inner/Outer Ring type)THK RU66 crossed roller bearing high precision bearing

Since the mounting holes are provided, the model does not require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, ensuring stable rotation accuracy and torque.
