Their rollers between the inner ring and the outer ring, the interval to intersect at right angles to each other are arranged.
They can withstand the load from all directions (eg axial thrust load or momentum, etc.). Because the surface of the roller and the track into a linear contact and therefore, the bearing load and by the possibility of elastic deformation is small. This type of bearings are widely used in industrial automation, such as robots, machine tools and medical facilities, and need high rigidity, high speed close and still ensure accurate the occasion.
RU series crossed cylindrical roller bearings, because the outer ring and inner ring have mounting holes, there is no need to fix the flange and support during installation. In addition, since the outer ring and the inner ring are of integral structure, the installation has almost no effect on performance, so stable rotation accuracy and can be obtained. Suitable for occasions where the outer ring and inner ring rotate.
