Introduction of Crossed Roller Bearing
Crossed roller bearings are cylindrical rollers or tapered rollers that are arranged perpendicular to each other through spacers on the 90-degree V-groove rolling surface, so crossed roller bearings can bear radial loads, axial loads and moments Loads such as loads in multiple directions. The size of the inner and outer ring is miniaturized, the ultra-thin form is closer to the limit of the small size, and has high rigidity, and the accuracy can reach P5, P4, P2 level. Therefore, it is suitable for joint parts and rotary parts of industrial robots, rotary tables of machining centers, precision rotary tables, medical machines, calculators, military industry, IC manufacturing equipment and other equipment.(HONBbearing02)
The inner and outer rings of this series of models are of integrated structure and are used for the rotation of the outer and inner rings.
This series of models is a compact type that reduces the thickness of RB type inner and outer rings to the limit. Suitable for parts that require light weight and compact design, such as industrial robots and manipulator rotation parts.

Characteristics of crossed roller bearings:
1. Excellent rotation accuracy:
The internal structure of the crossed roller bearing adopts the rollers to be vertically crossed at 90 °, and the rollers are equipped with spacers or spacers to prevent the tilting of the rollers or friction between the rollers, which effectively prevents the rotation torque increase. In addition, there will be no contact or locking phenomenon of the roller; at the same time, because the inner and outer rings are divided structures, the gap can be adjusted, and even if preload is applied, high-precision rotational movement can be obtained.
2. Simplified operation and installation:
The outer ring or inner ring, which is divided into two parts, is fixed together after the roller and the cage are installed, so the operation is very simple during installation.
3. Withstand large axial and radial loads:
Because the rollers are arranged vertically on the rolling surface of the 90 ° V-groove through the spacers, this design allows the cross roller bearings to withstand all radial loads, axial loads and moment loads. Directional load.
4. Significantly save installation space:
The size of the inner and outer rings of the crossed roller bearing is minimized, especially 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 part or rotating part of the industrial robot, and the machining center It is widely used in worktables, manipulator rotating parts, precision rotating worktables, medical instruments, measuring instruments, and IC manufacturing equipment.

Crossed roller bearing type:
1. RB type cross roller bearing (outer ring split type, inner ring rotation)
1. RB type cross roller bearing (outer ring split type, inner ring rotation)
This series of models is the basic type of crossed cylindrical roller bearings. The size of the inner and outer rings is minimized. Its structure is that the outer ring is divided and the inner ring is a one-piece design. .
2. RU type (integrated inner and outer ring)
Since this series of models have been processed with mounting holes, there is no need for fixing flanges and supporting seats. In addition, due to the integrated inner and outer ring structure with a seat, the installation has almost no effect on performance, so stable rotation accuracy and torque can be obtained. Can be used for outer ring and inner ring rotation.

3.CRBH type (integrated inner and outer ring)
The inner and outer rings of this series of models are of integrated structure and are used for the rotation of the outer and inner rings.
4.RA type (outer ring split type, inner ring rotation)
