The bearings of industrial robotics have important influence on the performance of running stability, repetitive positioning accuracy, motion precision and reliability of the robot. At present, there are many types of bearings used for robots, such as thin-section bearings, cross-roller bearings, harmonic reducer bearings and spherical plain bearings.



Bearing used for the waist of industrial robots required high accuracy and high rigidity; When for elbow and wrist, bearing is required compact, lightweight and adaptable to hostile environments. Same to other types of robots, the bearing capacity, speed capacity, service life, rotation accuracy and other mechanical properties, environmental requirements must take into accont when design a robotics bearing.


After continuous technical research, "luoyang huigong bearing" have work out a full set of production processes of cross-roller bearing. The size of the inner and outer rings of the crossed roller bearing is minimized, especially the ultra-thin structure is a small size close to the limit, and has high rigidity, and the accuracy can reach P5, P4, P2, the rotation accuracy of 1.5 microns, but the wall thickness only have 3 mm. So this series crossed roller bearing is most suitable for industrial robots rotary table of a mechanical machining center, a rotating part of a manipulator, precision rotary table, medical instrument, measuring instrument, and IC manufacturing device. With continuously enrich the types of bearings, improve bearing quality and performance. "luoyang huigong bearing company" has also developed a special harmonic reducer machine bearings, RV reducer bearings and other special bearings.
