1. Save installation space

The size of the inner and outer rings of the crossed roller bearing is miniaturized to a minimum, especially the ultra-thin structure is a small size close to the limit, and has high rigidity, so it is suitable for the joint parts or rotating parts of industrial robots, and the rotating work of machining centers Tables, rotating parts of manipulators, precision rotary tables, medical instruments, measuring instruments, IC manufacturing equipment, etc.

2. Simplified operation and installation

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

3. Excellent rotation accuracy

The internal structure of the crossed roller bearing adopts rollers arranged vertically and intersecting each other at 90°. There are spacers or spacers between the rollers, which can prevent the rollers from tilting or rubbing against each other, and effectively prevent the rotation torque. Increase.

4. Pre-bear large axial and radial loads

Because the rollers are vertically arranged on the 90° V-groove rolling surface through the spacer, this design enables the crossed roller bearing to withstand large radial loads, axial loads and moment loads, etc. direction load.

5. The crossed roller bearing can bear radial and axial loads at the same time, so it can be much simpler than the bearing structure of various combinations.

6. Due to high rotation efficiency and low heat dissipation, the consumption of lubricating grease is small.

7. The radial and axial dimensions of bearings can be maximized, so the space is saved, and it can be used in high-precision and high-rigidity occasions with small space requirements.

8. Bearings can be easily assembled in all directions of the main shaft, and mass production can be realized through standardization and serialization, and the assembly and use are more convenient.
