Face mount crossed roller bearing are a special type of bearing

Face mount crossed roller bearing are a special type of bearing with a split inner ring and a rotating outer ring. Due to their special structure, they are often used as spherical bearings in industrial robots.
Main features of face mount crossed roller bearing

1. Excellent rotation accuracy
The internal structure of the face mount crossed roller bearing adopts rollers arranged perpendicularly at 90°, and spacers or spacers are installed between the rollers to prevent the rollers from tilting or rubbing against each other, effectively preventing the increase of rotation torque. In addition, there will be no contact or locking of the rollers; at the same time, because the inner and outer rings are divided, the gap can be adjusted, and high-precision rotation can be obtained even if preload is applied.
2. Simplified operation and installation
The face mount crossed roller bearing outer ring or inner ring divided into two parts is fixed together after the rollers and retainers are installed, so the operation is very simple during installation.
3. Bear large axial and radial loads
Because the rollers are arranged perpendicularly to each other on the 90° V-groove rolling surface through the spacer retainer, this design enables the cross roller bearing to withstand large radial loads, axial loads, moment loads and other loads in all directions.

4. Greatly save installation space
The inner and outer ring sizes of the face mount crossed roller bearing are minimized, especially the ultra-thin structure is close to the limit of small size, and has high rigidity, so it is most suitable for a wide range of uses such as the joints or rotating parts of industrial robots, rotary tables of machining centers, rotating parts of manipulators, precision rotary tables, medical instruments, measuring instruments, IC manufacturing equipment, etc.
