RU Series Cross Roller Bearings Are Designed As An Integral Structure For Inner And Outer Rings. Because The Inner And Outer Rings Have Machined Installation Holes, There Is No Need To Fix Flanges And Support Supports, Which Shortens The Axial Space Distance And Optimizes The Use Mechanism. In Addition, Because Of The Integrated Inner And Outer Rings Structure With Seat, Installation Has Little Effect On Performance, So Stable Rotation Accuracy And Torque Can Be Obtained, And The Outer Rings Can Be Used. It Is Suitable For Both Inner Ring Rotating Mechanism And Is Widely Used In Robot Waist Joints, Welding Multi-Station Rotary Table, Communication Radar, Precision Measuring Instruments And So On.
