Industrial robot bearings-application advantages of crossed roller bearings

Excellent rotational accuracy

Spacers or isolation blocks are installed between the rollers, which can prevent the tilt of the rollers or the mutual friction between the rollers, effectively preventing the increase in rotation torque; and there will be no contact or locking of one side of the rollers; At the same time, because the inner and outer rings are divided structures, the gap can be adjusted, and high-precision rotation can be obtained even if preload is applied.

Simplified operation and installation

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

bear heavy load

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

Significantly save installation space

The dimensions of the inner and outer rings of crossed roller bearings are miniaturized, and the ultra-thin structure in particular is close to the limit of small size and has high rigidity, so it is very suitable for joints or rotating parts of industrial robots.
