1. Introduction to RB/RE/CRBC/CRBH/SX Thin Section Bearings
Single row crossed roller slewing bearing is a kind of thin section ball bearings, With the Cross-Roller Ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads. Since the inner and outer rings are designed to be separable, the bearing clearance can be adjusted. In addition, highly accurate rotary motion is ensured through adjusting the bearing clearance to provide a preload.
2. Structure
RU series, integrated inner/outer ring type
RB series, separable outer ring type for inner ring rotation
RE series, separable inner ring type for outer ring rotation
CRB series
SX series

3. Features
High precision: Precision at P4, P2.
High rigidity: These ball bearings are with preload.
High load capacity: These thin section bearings can support axial load, radial load, and tilting load.
Small volume: These slewing bearings can save space for the machine.

4. Application

Since the Cross-Roller slewing ring bearings 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.
