What’s the Feature of Cross Roller Bearing?

Cross-roller bearings, because of the split inner ring or outer ring, are fixed with the cross roller collar after loading the roller and spacer, to prevent separation from each other, so when installing the cross roller collar simple. Since the rollers are arranged in a cross arrangement, only one set of crossed roller collars can withstand loads in all directions, and the rigidity is increased by 3 to 4 times compared with the conventional model. At the same time, since the inner ring or the outer ring of the crossed roller bearing has a two-divided structure, the bearing clearance can be adjusted, and even if a preload is applied, a high-precision rotational motion can be obtained.

1. With excellent rotation accuracy

The internal structure of the crossed roller bearing is arranged at 90° perpendicular to each other by rollers.

A spacer or spacer is placed between the rollers to prevent the rollers from tilting between the rollers. In addition, the contact phenomenon or the locking phenomenon of the roller does not occur; at the same time, since the inner and outer rings are divided structures, the gap can be adjusted, and even if a preload is applied, a high-precision rotational motion can be obtained.

2. The operation is simplified

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

3. Withstand large axial and radial loads

Since the rollers are vertically aligned with each other by the spacers on the V-shaped groove rolling surface of 90°.

4. Greatly save installation space

The size of the inner and outer rings of the crossed roller bearing is miniaturized to a minimum. In particular, the ultra-thin structure is a small size close to the limit and has high rigidity, so it is most suitable for the rotation of the joint or the rotating part of the industrial robot and the machining center. A wide range of applications such as work tables, robot rotating parts, precision rotary tables, medical instruments, measuring instruments, and IC manufacturing equipment.

5. High speed capability

6. Reduce shaft length and machining cost, thermal expansion leads to limited variation in geometry

7. Nylon separator, low moment of inertia, low starting torque, easy to control angular division

8. Optimize the pre-tightening force, the rigidity is high, and the guiding roller has high running precision.

9. Carburized steel provides excellent impact resistance and surface abrasion resistance

10. Simple but fully lubricated
