Cross Roller Rotary Guide JRA Series

The JRA Series is a lightweight, compact cross roller rotary guide designed with the inner and outer ring thickness minimized to achieve a slim profile. It features a separable outer ring and rotating inner ring structure, making it suitable for applications where inner ring rotation is required.

Despite its compact size, the JRA series can simultaneously support radial, axial, and moment loads thanks to the orthogonally arranged cylindrical rollers in a 90° V-groove. This design delivers high rigidity and stable rotational accuracy, making the JRA series ideal for compact rotary mechanisms, robot joints, precision rotary tables, and measuring equipment.
