As one of the key components of industrial robots, industrial robot bearings are suitable for joint parts or rotating parts of industrial robots, rotating tables of machining centers, manipulator rotating parts, precision rotating tables, medical instruments, measuring instruments, and IC manufacturing devices And other widely used. It mainly includes two types of bearings for industrial robots, one is the uniform cross-section thin-wall bearing, and the other is the crossed cylindrical roller bearing. There are also harmonic reducer bearings, linear bearings, joint bearings, etc., but mainly the first two types of bearings.

Classification of industrial robot bearings:

1. Crossed roller bearings

The characteristics of crossed roller bearings: crossed roller bearings, cylindrical rollers or tapered rollers are arranged perpendicular to each other on the 90-degree V-groove rolling surface through spacers, so the crossed roller bearings can bear radial Loads in multiple directions such as load, axial load and moment load. The size of the inner and outer rings is miniaturized, and the ultra-thin form is even closer to the limit of small size, and has high rigidity, and the accuracy can reach P5, P4, and P2. Therefore, it is suitable for joints and rotating parts of industrial robots, rotating tables of machining centers, precision rotating tables, medical machines, calculators, military industry, IC manufacturing equipment and other equipment.

Second, uniform section thin-walled bearings

The uniform section thin-walled bearing is composed of seven open series and five sealed series. There are three types of open series: radial contact type C, angular contact type A and four-point contact X type. Advantages of thin-walled constant-section bearings: Thin-walled bearings have realized extremely thin bearing sections, and also realized miniaturization and light weight of products. The variety of products expands its scope of use.

Product features of thin-walled constant-section bearing: In order to obtain the bearing's low friction torque, high rigidity, and good rotation accuracy, steel balls with small outer diameters are used. The use of hollow shafts ensures light weight and space for wiring. The thin-walled 6700 and 6800 series have various types of dust cover, flanged, stainless steel, and wide-format, etc., with a complete range.

The main use of thin-walled and other cross-section bearings: stepper motors, medical equipment, office equipment, testing equipment, speed reduction devices, robots, optical imaging equipment, rotary encoders.
