Industrial Robots High Precision Crossed Roller Bearing RA RB Series Compact Design High Rigidity High Rotation Accuracy
The RA and RB Series Crossed Roller Bearings are high precision bearings specifically designed for industrial robot joints and rotary units. Featuring a crossed roller arrangement, they simultaneously handle radial loads, axial loads, and overturning moments. With a compact design, high rigidity, high rotation accuracy, and low friction characteristics, they ensure smooth and precise movement of industrial robots while extending service life.
