Cross roller bearing is a special type of bearing with split inner ring and rotating outer ring. Because the divided inner ring or outer ring is fixed with the cross roller shaft ring after installing the roller and spacer, so as to prevent separation from each other, the operation is simple when installing the cross roller shaft ring. Due to the cross arrangement of rollers, only one set of cross roller collar can bear the load in all directions. Compared with the traditional model, the rigidity is increased by 3 ~ 4 times.
At the same time, because the inner ring or outer ring of the cross roller bearing is a two-part structure, the bearing clearance can be adjusted, and high-precision rotation can be obtained even if preload is applied. Moreover, because of its special structure, it is commonly used as joint bearing in industrial robot.
Their rollers are arranged at right angles to each other at intervals between the inner wheel and the outer wheel. They can simultaneously bear loads from all directions (such as axial, thrust or momentum loads). Because the roller is in linear contact with the track surface, the possibility of elastic deformation of the shaft under load is very small. This type of bearing is widely used in occasions such as industrial automatic robots, working machinery and medical facilities, which need high rigidity, tightness and high speed to ensure accuracy.
In the cross roller bearing, because the cylindrical rollers are arranged vertically to each other through the spacer retainer, a cross roller bearing can bear the loads in all directions such as radial load, axial load and torque load. The size of the inner and outer ring is miniaturized to the minimum, especially the extremely thin type. It is a small size close to the limit and has high rigidity. Therefore, it is most suitable for the joint or rotating part of industrial robot, rotating worktable of machining center, rotating part of manipulator, precision rotating worktable, medical machine, gauge, IC manufacturing device, etc.
