Cross Roller Slewing Bearings without Teeth

General introduction:

Crossed cylindrical roller slewing bearing is a kind of slewing bearing with vertical cross arrangement of cylindrical rollers between the inner and outer rings of the bearing. The rollers are in line contact with the raceway, with good rigidity. The elastic deformation of the bearing under load is very small, and it can bear radial load, axial load and torque load at the same time. It is especially suitable for occasions requiring high rigidity and high rotation accuracy.

Characteristics of cross roller slewing bearing:

1. Excellent rotation accuracy

The internal structure of the cross roller slewing bearing adopts rollers arranged in 90 ° perpendicular to each other, and the rollers are equipped with spacing retainers or isolation blocks, which can prevent the tilt of the rollers from rubbing each other and effectively prevent the increase of rotation torque. In addition, one side of the roller will not contact or lock;

2. Simplified operation and installation

The outer ring or inner ring that is divided into two parts is fixed together after the roller and retainer are installed, so the operation is very simple during installation.

3. Bear large axial and radial loads

Because the rollers are arranged vertically with each other on the V-groove rolling surface at 90 ° through the spacing retainer, this design enables the cross roller bearing to bear large radial load, axial load, torque load and other loads in all directions.

4. Significantly save installation space

The size of the inner and outer rings of the cross roller slewing bearing is minimized, especially the ultra-thin structure is close to the limit of small size, and has high rigidity.
