Crossed Roller Bearing introduction
Features of the Crossed Roller Ring
Structure and Features
With the Cross-Roller Ring, cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90° V groove, separated from each other by a spacer retainer. This design allows just 1 bearing to receive loads in all directions including radial, axial and moment loads. Since 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 and IC manufacturing machines.
Types of the Cross-Roller Ring
Types and Features
Model RU (Integrated Inner/Outer Ring Type)
Since holes are drilled for mounting, the need for a presser fl CHINAMFG and a housing is eliminated. Also, owing to the integrated inner/outer ring type stryucture with washer, there is almost no effect from installation on performance, allowing stable rotational accuracy and torque to be obtained. Can be used for both outer and inner ring rotation.
Model RB (Separable Outer Ring Type for Inner Ring Rotation)
Cross-Roller Ring basic type, with a separable outer ring, and an inner ring integrated with the main body.It is used in locations where the rotational accuracy of the inner ring is required. It is used, for example, in the swivel portions of index tables of machine tools.
Model RE (Two-piece Inner Ring Type for Outer Ring Rotation)
Main dimensions are the same as model RB. This model is used in locations where the rotational accuracy of the outer ring is required.
Model RA (Separable Outer Ring Type for Inner Ring Rotation)
A compact type similar to model RB with the thinnest possible inner and outer rings. Optimal for locations requiring a light-weight and compact design such as the swivel portions of robots and manipulators.
