Introduction Of Cross Roller Bearing
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.
