RU type is two pieces Inner Ring Type for Rotation.
RU series crossed roller bearing is an integrated inner and outer ring type crossed roller bearings that can be used for both inner ring rotation and outer ring rotation. with the Cross-Roller Ring, cylindrical rollers are arranged with each roller perpendicular to the adjacent roller,in a 90 degree V groove, separated from each other by a spacer retainer.This kind of design allows just one bearing will be to receive loads in all directions including radial load, axial load and moment load.Because the Cross-Roller Ring achieves high rigidity despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications
such as joints and swiveling units of industrial robots,swiveling tables of machining centers,rotary units of manipulators,precision rotary tables,medical equipment,measuring instruments,IC manufacturing achines,high precision machine tools and other precision machine. High Rotation Accuracy of RU crossed roller bearing :
The spacer retainer fitting among cross-arrayed rollers prevents rollers from skewing and the rotational torque from increasing due to friction between rollers.Unlike conventional types steel sheet retainers,the Cross-Roller Ring does not cause unilateral contact of roller or seize. Thus,even under a preload, the Cross-Roller Ring provides stable otation.Because the inner and outer rings are designed to be separable, the RU crossed roller bearing clearance can be adjusted. In addition, a preload can be applied. These features enable accurate rotation.
