In addition, the surface of the roller and the rolling track is linear contact. So, when the bearing is loaded, the loading area will be very large. Thus, the elastic deformation will be less, and the bearing will achieve a long service life. Each roller in Crossed Roller Bearing is crossed at 90° angle, which is able to bear the loading force from axial, radial and the other direction at the same time.
