Robot bearing

Industrial robot bearing mainly include two kinds of bearings for industrial robots, one is thin-walled bearings with equal cross-section, the other is cross-section cylindrical roller bearings. In addition, there are harmonic reducer bearings, linear bearings, joint bearings and so on, which are most suitable for industrial robots’joint parts or rotating parts, rotating worktable of machining center, rotating part of manipulator, precision rotating worktable, medical instruments, measuring instruments, IC manufacturing devices and other widely used.

As one of the key components of industrial robots, bearings of industrial robots mainly include two kinds of bearings for industrial robots, one is thin-walled bearings with equal cross-section, the other is cross-section cylindrical roller bearings. In addition, there are harmonic reducer bearings, linear bearings, joint bearings and so on, but mainly the first two kinds of bearings.
Bearing characteristics of industrial robots: 1. Bearing comprehensive loads in axial, radial and overturning directions; 2. Thin-walled bearings; 3. High rotary positioning accuracy. Any bearing that meets the design requirements can be used in industrial robot arms, rotary joints, chassis and other parts.

A harmonic gear is a strain wave gear which can improve certain characteristics compared to traditional gearing systems, It is very commonly implemented in robotics today and used in aerospace as well, for gear reduction but may also be used to increase rotational speed, or for differential gearing

One part called wave generator is very important. The wave generator is made up of two separate parts: an elliptical disk called a wave generator plug and an outer ball bearing.

Cross-industry Application of Industrial Robot Bearings

Industrial robotic bearings are basically thin-walled high-precision bearings. The accuracy of these bearings is above P5 level, and some of them meet the requirements of P2 level. They belong to ultra-high precision bearings. It is very difficult to process and produce. At present, domestic demand largely depends on imports. With the development of robotic industry, robotic bearings are produced. The industry is also in a period of rapid development. Many professional precision thin-walled bearings manufacturers have appeared in Luoyang and other bearing industry bases, filling the gap in the domestic market. Industrial robotic bearings are not only used in the field of industrial robots, but also in high-precision measurement equipment, aerospace, astronomical research, medical equipment and other sophisticated fields.
