Industrial robot bearings are key components of industrial robots. Industrial robot bearings mainly include thin-walled bearings, crossed cylindrical roller bearings, harmonic reducer bearings and spherical bearings, but mainly crossed roller bearings.

The structural features of the crossed roller bearings in the welding robot joints: The cylindrical rollers are arranged vertically and crosswise in the inner and outer raceways of the bearings, and a single bearing can simultaneously withstand the combined loads of radial force, bidirectional axial force and overturning moment.

The bearings have large load-bearing capacity, good rigidity, high rotation accuracy, easy installation, space saving, reduced weight, significantly reduced friction, and provide good rotation accuracy. It makes it possible to lighten and miniaturize the host. RCL specializes in the production, supply and sales of deep groove ball and thin-walled bearings, especially in the thin-walled series.
