RB cross roller ring belongs to the basic model of high precision cross roller bearings. Its cylindrical rollers are placed in a 90°V groove, with each roller arranged perpendicular to the adjacent one, and separated from each other by a space retainer. RB crossed roller ring `s outer ring is designed to be separable, and fixed by screw, suited for locations where the rotation accuracy of the inner ring is required.

RB Series Crossed Roller Bearing Features

1、Sustain radial, axial ,and moment loads at the same time
2、High rotation accuracy is ensured by adjusting the bearing clearance to preload
3、Stable rotation, spacer retainer keeps rollers in the proper position, preventing them from skewing, thus eliminates friction between rollers.

Applications

RB cross roller rings are especially suitable for applications where space is limited, while high rigidity and high rotation accuracy are required. 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, and IC manufacturing machines.
