Cross Roller Ring - RU, XU, XSU Series

Features of RU XU XSU Cross Roller Bearings

RU, XU, XSU series cross roller ring are machined with the mounting holes, so, they do not request the mounting flanges and housings. Besides, unlike the other series, their inner ring and outer ring are both integral and equipped with washers, therefore, the mounting process minimally affects their performance. All these features ensure the stable rotation accuracy and torque. So, the cross roller ring type is suitable for industrial applications of both inner ring rotation and outer ring rotation.
