Crossed Roller Bearing
What is Crossed Roller Bearing?
Crossed roller bearings, including crossed cylindrical roller bearings and crossed tapered roller bearings, are 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, moment load, and other combined load.
Classification Of Crossed Roller Bearing
Cross Cylindrical Roller Bearing
Component structure: outer ring, inner ring, cylindrical roller, and isolation block. Cylindrical rollers are crossed between V-races, crossed roller bearing is suitable for various high precision and high rigidity applications.
Cross Tapered Roller Bearing
Component structure: outer ring, inner ring, cylindrical roller, and isolation block. Cylindrical rollers are crossed between V-races, crossed roller bearing is suitable for various high precision and high rigidity applications.
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, and rings and rollers have small elastic deformation when the bearing achieves 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 Installation
THB cross roller ring bearing is with two types of two-piece outer rings, inner rings, and 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 with the minimum possible dimensions of the inner and outer rings, the cross roller slewing bearing is the optimal option for the 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.

FAQ Of Crossed Roller Bearing
Due to their internal design, ball bearings cannot usually be disassembled down to the component level; therefore, they cannot usually be refurbished.
The two biggest factors affecting the starting and running torque of the bearing are the seal design and lubricant selection. The shaft and bearing seat fit, component accuracy and surface finish, and retainer design also have some influence.
In higher speed applications, non-contact sealing devices are usually required to minimize operating torque and heat generation, so oil baffle rings and secondary sealing devices are usually required. Flowing oil lubrication systems are usually the best solution.
After proper installation, most seated bearings only need to be relubricated regularly with a small amount of grease and checked to ensure that they operate at low temperatures, quietness, and sufficient accuracy.
This depends on many factors, such as the application’s load conditions, operating speed, duty cycle, temperature, and operating environment. The technical information section of this website provides some basic information. Our engineers can help you determine more specific theoretical life calculations.
When noise and/or operating temperature increase or operating accuracy decreases, bearings should be replaced.
