RB Series Thin Section Robot Arm Slewing Cross Roller Bearing RB17020

Cross roller bearing

With the Cross-Roller Ring, cylindrical rollers are arranged crosswise, 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 one 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.

RB slim type crossed roller bearing provides high and stable running accuracy, suited for precision detecting instrument, robot joints, direct drive torque motor, high-precision turntable, etc.

Features of cross roller bearing:

1.with excellent rotational accuracy

2. Installing simplifies operation

3. Bear large axial and radial loads

4.Significant savings in installation space

5. High speed capability is limited to changes .

6. Shaft length and reduce processing costs, the geometry of thermal expansion

7. Nylon spacer, low inertia, low starting torque, easy to control angle indexing

8. Optimization of preload, rigidity, high precision guide rollers running  

9. Carburizing steel provides excellent impact resistance and su
