Precision Cross Roller Bearing, the inner structure of which adopts the vertical and cross arrangement of cylindrical rollers with 90°, can bear radial load, double-direction thrust loads and overturning moment at the same time. Combined with its high rigidity, it can be applied to the joints and rotating parts of industrial robots, rotary tables of machining centers, rotating parts of manipulators, precision rotary tables, medical equipments, measuring instruments, IC manufacturing machines, etc.
Precision Cross Roller Bearing has three structure types, including bearing with cage, with separator, and with full complement. Cage and separator types are suitable to low friction moment and high-speed rotation, while full complement is suitable to low-speed rotation and heavy load.
