Crossed roller bearing is a special type of bearing with split inner ring and outer ring rotation. The divided inner ring or outer ring is fixed with the cross roller collar after the roller and the spacer are installed to prevent separation, so the operation is simple when installing the cross roller collar. Because the rollers are arranged crosswise, only one set of crossed roller collars can bear the load in all directions. Compared with the traditional model, the rigidity is increased by 3 to 4 times. At the same time, because the inner or outer ring of the crossed roller bearing has a two-part structure, the bearing gap can be adjusted, and even if a preload is applied, a high-precision rotary motion can be obtained. Moreover, due to its special structure, it is usually used as an articulated bearing in industrial robots.

 In the crossed roller bearing, the cylindrical rollers are arranged perpendicular to each other through the spacers on the upper side. Therefore, a single crossed roller bearing can bear the load in all directions such as radial load, axial load and moment load. The dimensions of the inner and outer rings are miniaturized to a minimum. Especially the extremely thin type is a small size close to the limit and has high rigidity. Therefore, it is most suitable for the joints or rotating parts of industrial robots, rotary tables of machining centers, Applications for robotic rotary parts, precision rotary tables, medical equipment, gauges, IC manufacturing equipment, etc.

    Crossed roller bearings, because the inner or outer ring is divided, after the rollers and spacers are installed, they are fixed with the cross roller collars to prevent them from being separated from each other. Therefore, it is necessary to operate the cross roller collar simple. Because the rollers are arranged crosswise, only one set of crossed roller collars can bear the load in all directions. Compared with the traditional model, the rigidity is increased by 3 to 4 times. At the same time, because the inner or outer ring of the crossed roller bearing has a two-part structure, the bearing gap can be adjusted, and even if a preload is applied, a high-precision rotary motion can be obtained.
