Crossed roller bearings are two columns of cylindrical roller in a 90 degree V rolling path arranged vertical cross each other by nylon isolation block, so they can withstand radial load, axial load and torque load in the direction of the load. The size of inner ring and outer ring are both miniaturized, more, thin form is close to the limit of small size, and with high rigidity, the accuracy of crossed roller bearing can reach grade P2. Therefore they are suitable for industrial robot joint rotation, the rotation of the machining center, precision rotary worktable, medical machine, calculator, IC manufacturing devices and other equipment.

Rotation accuracy: 
the vertical row of roller in the bearing is fitted with a block, which prevents the roller's tilt and the friction between the roller, reduces the rotation torque. In addition, the edge stress concentration or lock of the roller will not occur when compared with the steel plate being used before. At the same time, because inner ring and outer ring are separable constructs, bearing clearance can be adjusted, even if applied preload, they can also rotate accurately and smoothly.
