Cross 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 turrets, large radio and optical telescopes, rotating cameras , steering pivot and continuous casting machine, height-limited pivot microscope stage, rod center support shaft, rotary bogie, welding bracket, rotary assembly fixture, industrial robot, precision rotary table, medical equipment, measuring instruments, IC manufacturing Devices and so on.
1, with excellent rotation accuracy
Crossed roller bearing
The internal structure of the crossed roller bearing is arranged at 90° perpendicular to each other by rollers. The spacers or spacers are arranged between the rollers to prevent the rollers of the rollers from being mutually inspected and prevent the rotational torque. Increase. In addition, the phenomenon of contact or locking of the roller does not occur;
Non-standard cross roller bearings are also available because the inner and outer rings are divided and the gap can be adjusted to obtain high-precision rotary motion even when preloading is applied.
2, the operation is simplified
The outer ring or inner ring that is divided into two parts is fixed after being loaded into the roller and the retainer, so the operation is very simple to install.
3. Withstand large axial and radial loads
Because the rollers are vertically aligned with each other through the spacers on the 90° V-groove rolling surface, this design allows the crossed roller bearings to withstand large radial loads, axial loads and moment loads. Directional load.
4, greatly save installation space
The size of the inner and outer rings of the crossed roller bearing is miniaturized to a small extent. The ultra-thin structure is a small size close to the limit and has high rigidity, so it is suitable for the rotary work of the joint or rotating part of the industrial robot and the machining center. Wide range of applications such as table, robot rotating parts, precision rotary table, medical instruments, measuring instruments, and IC manufacturing equipment.
