Crossed Roller Bearings

Crossed Roller Bearings

HIWIN Crossed Roller Bearings consist mainly of an outer ring, an inner ring and a number of rollers and spacers. The rollers lie between the inner ring and the outer ring. The spacer is placed between rollers to prevent mutual friction and  decrease torque resistance for rotation. In addition, the surface of the roller and the rolling track are in linear contact. When the bearing is loaded, the loading area will be very large. Thus, the elastic deformation will be less, and the bearing will achieve longer service life. Each roller in a Crossed Roller Bearing is creossed at a 90^o angle, allowing loading force from multiple directions at the same time.
HIWIN offers the following six types of Crossed Roller Bearings defined by the following as the split outer raing type (CRBA), the split inner ring type (CRBB), the high rigidity type (CEBC), the split outer ring with mounting holes (CRBD), the high rigidity with mounting holes (CRBE) and the customized type (CRBX). The split outer ring type is suitable for rotating both the inner ring and outer ring. The mounting holes can be used to aid in the assembly. The customized type type can be modified to meet the customer requirements. Crossed Roller Bearings possess high rigidity and high rotating accuracy, which can be widely used in industrial automation control, robotics, machine tools, inspection and medical devices.
