THK RU Series Cross Roller Rings (Integrated Type)

The THK RU Series cross roller rings feature an integrated inner and outer ring design that allows direct mounting without the need for separate housings, simplifying installation and reducing overall assembly size. Cylindrical rollers arranged in a cross pattern enable the bearing to simultaneously support radial, axial, and moment loads within a single compact unit.

The integrated design delivers high rigidity, consistent rotational accuracy, and stable performance under combined loading conditions, making the RU Series well suited for precision rotary tables, robotic joints, semiconductor equipment, and other space-saving rotary applications requiring high accuracy and reliability. Double seals (UU) provide effective contamination protection for reliable operation in industrial environments.
