Ultra-thin Cross Roller Bearing RAU13008 with 130mm Inner Diameter for Industrial Robot Joints
The RAU13008 Ultra-thin Cross Roller Bearing is designed for industrial robot joints and precision rotary applications requiring compact structure, high rigidity, and accurate positioning.
With a 130mm inner diameter, the RAU13008 features an ultra-thin profile combined with a crossed cylindrical roller structure. Rollers are arranged alternately at 90°, allowing the bearing to support radial loads, axial loads, and moment loads simultaneously.
Its lightweight and space-saving design makes it ideal for robotic arm joints, collaborative robots, and precision automation systems where installation space is limited but stiffness and precision remain critical.
