RU85 Cross Roller Bearing


Since the mounting holes are provided the model does not require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, ensuring stable rotation accuracy and torque. 
This model can be used for both inner-ring rotation and outer-ring rotation.


RU Crossed Roller Bearing Features:

The structure of the crossed cylindrical roller bearing is divided into three types of outer ring split type, inner ring split type and inner and outer ring integrated type. The rolling elements are short cylindrical rollers arranged at 90 ° to each other in a V-shaped raceway. The rollers are separated by a spacer.

This structural design allows a single bearing to withstand axial loads, radial loads, and overturning moments. At the same time, bearings have high rigidity, high rotation accuracy and high bearing capacity, so they are suitable for rotary joints of industrial robots, rotary tables of machining centers, precision rotary tables, medical machines, measuring instruments, etc.

Because the rollers are arranged in a cross, 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. Due to its special structure, it is usually used as an articulated bearing in industrial robots.
