Crossed cylindrical roller bearings can be widely used in precision rotary indexing tables for machine tools, vertical and horizontal boring machines, vertical grinders, rotary surface grinders, large hobbing machines, guns and radar turntables, large radio and optical telescopes, rotary cameras , Steering Pivot and Continuous Casting Machine, Pivot Microscope Table with Limited Height, Rod Center Pivot, Rotary Bogie, Welding Bracket, Swivel Assembly Fixture, Industrial Robot, Precision Rotary Table, Medical Instrument, Measuring Instrument, IC Manufacturing Device and more.
1.With rotation accuracy
The internal structure of the crossed roller bearings adopts the rollers arranged at 90 ° to cross each other vertically. Spacers or spacers are installed between the rollers, which can prevent the tilting of the rollers from mutual inspection between the cargo rollers and effectively prevent the rotating torque. Increase. In addition, one side of the roller will not contact or lock up;
Non-standard Crossed Roller Bearings Because the inner and outer rings have a split structure, the gap can be adjusted, and even if preload is applied, high-precision rotary motion can be obtained.
2.Simplified operation and installation
The outer ring or inner ring that is divided into two parts is fixed together after the roller and cage are installed, so the operation is very simple during installation.
3.Withstand large axial and radial loads
Because the rollers are arranged perpendicular to each other on the V-shaped groove rolling surface at 90 ° through the spacer, this design enables the crossed roller bearing to bear all the large radial load, axial load and moment load. Directional load.
4. Significantly save installation space
The size of the inner and outer ring of the crossed roller bearing is minimized, especially the ultra-thin structure is a small size close to the limit, and it has high rigidity, so it is most suitable for the joints or rotating parts of industrial robots and the rotation of machining centers A wide range of applications include worktables, robotic rotating parts, precision rotary worktables, medical instruments, measuring instruments, and IC manufacturing equipment.
