Application areas of small crossed roller bearings

Cylindrical Roller Bearings

Small Crossed Roller Bearings

Have their rollers arranged at right angles to each other between the inner and outer wheels at intervals. They can simultaneously withstand the load from all directions (such as axial, thrust or momentum load, etc.). Since the rollers are in contact with the track surface, the possibility of elastic deformation of the bearing due to the load is very small. In crossed roller bearings, because the cylindrical rollers are arranged perpendicular to each other through the spacing keeper on the rolling surface of the 90° V groove, so one crossed roller bearing can withstand radial load, axial load and moment load in all directions.

CRBT Crossed Roller Bearings

The small crossed roller bearings have high accuracy and prevent the increase of rotating torque because they are equipped with spacer keepers between the vertically arranged rollers, which prevent the rollers from falling sideways or the rollers from rubbing against each other. In addition, compared with the conventional type of iron plate retainer, there is no contact or locking of the rollers on one side. Stable rotational motion can be obtained even when preload is applied. Also, since the inner ring or outer ring is divided into two parts, it is possible to adjust the preload, so that rotational motion can be obtained.

The size of the inner and outer rings of the small crossed roller bearings is minimized, and the crossed roller bearings are particularly thin, so they are ideal for use in the joint or rotating part of industrial robots, the rotary table of machining centers, the rotary part of robots, precision rotary tables, medical equipment, measuring instruments, and IC manufacturing equipment.

Characteristics of small crossed roller bearings:

Since the divided inner or outer ring is fixed with the crossed roller ring after installing the roller and spacer keeper to prevent separation from each other, it is easy to operate when installing the crossed roller ring. Since the rollers are arranged crosswise, only one set of crossed roller rings can bear the load in each direction, and the rigidity is increased 3~4 times compared with the conventional type. At the same time, NTN imported bearings fork roller bearings because of cross roller bearing inner ring or outer ring is two split structure, bearing clearance can be adjusted, even if the preload is applied, but also can get high precision rotational movement.

Small crossed roller bearing use:

This type of bearing is widely used in such as industrial automatic robot, work machinery and medical facilities, etc., need high rigidity, tight and high speed can still ensure the accuracy of the occasion.
