RU Series (Integrated Inner/Outer Ring Type) Crossed Roller Bearing
The RU series bearings feature provided mounting holes, eliminating the need for a presser flange or housing. Additionally, with an integrated inner/outer ring structure and equipped with washers, their performance is minimally impacted by the mounting procedure. This ensures stable rotation accuracy and torque. This model supports both inner-ring rotation and outer-ring rotation, offering high flexibility and adaptability.
