XRU Series Cross Roller Bearings

XRU Series Cross Roller Bearings(Integrated Inner and Outer Rings, Inner Ring Rotation/Outer Ring Rotation, Featuring Mounting Holes and High Rigidity)

The XRU series of cross roller bearings can be used as a direct replacement for the RU series by THK and the CRBF series by IKO.

The XRU series boasts an innovative integrated design for both the inner and outer rings. With mounting holes present on both rings, the need for fixed flanges or support seats is eliminated, greatly simplifying the installation process. Furthermore, the integrated design, coupled with a protective casing, ensures that installation barely affects its performance. This allows for stable rotational accuracy and torque, making the bearings ideal for rotating mechanisms on either the outer or inner ring.
