The features of Crossed Roller Bearing
1. High rigidity Flexible rotation Accurate location
With the cross-roller bearing, cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90° V groove, rollers, and grooves are linear contact, rings and rollers have small elastic deformation when the bearing achieve loads, thus, it has high rigidity. Separated from each other by a spacer or retainer to prevent rollers from skewing and the friction between rollers, improving flexible rotation and working speed.
2. Simple operation and Install
With the types of two-piece outer rings, inner rings type, integrated structure with roller putting holes type, which is very easy to operate and install.
3. Achieve loads in axial, radial, and tilting moment
With the structure of a 90° V groove, cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, this design allows just one bearing to receive loads in all directions including radial, axial, and moment loads.
4. Save installation space
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 manufacture machines.
What is Crossed Roller Bearing?
Crossed cylindrical roller bearing is between the inner and outer ring: configuration of the corresponding rollers and composition. Compact structure, rolling surface for the line contact, so the shaft with force when the collar and rolling body elastic deformation is small while carrying radial, axial load and moment load and other combined load. These bearings are widely used in applications requiring high rigidity and high rotational accuracy and small bearing size requirements, such as industrial Mk robots, machine tools and medical equipment and other rotary positions.
