(Integrated Inner/Outer Ring Type)
The mounting holes of RU85 are provided, this model does not require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, ensuring stable rotation accuracy and torque. RU85 can be used for both inner-ring rotation and outer-ring rotation.
