XRB/XRA Roller Cross Bearing Crossed Roller Type with Steel Construction
Product Description:
The cross roller bearing is a kind of cylindrical roller bearings in the inner and outer rings between the vertical cross arrangement of the bearing.The roller is in line contact with the raceway and has good rigidity.The elastic deformation of bearing under load is very small.and can bear radial load , axial load and moment load at the same time,It is especially suitable for application occasion requiring high rigidity and high rotation accuracy .
Cross Roller Bearing is a kind of bearing with cylindrical rollers arranged crosswise, in which the rollers are guided by four point contact between the inner ring and outer ring, and it can bear the radial load, axial load and the combined load at the same time. Cross Roller Bearing has a high rigidity, high accuracy and high rotational speed, and can be used in large gear hobbing machine, industrial robot, high speed vertical lathe, precision circular indexing table, vertical boring machine, grinder table spindle etc.
Our Cross Roller Bearing offers various load capacities, low noise level and can be lubricated with oil or grease. It is available in two configurations: XRE Roller Bearing Crossed and Cylindrical Roller Bearing Crossed. The special XRB/XRA Roller Cross Bearing is suitable for radial, axial and moment loads with a high level of rigidity.
