Industrial robots are multifunctional, multi-degree-of-freedom mechanical devices that can be repeatedly programmed to complete certain operations or mobile operations under automatic control. They are important engineering automation equipment in modern manufacturing.

As one of the key accessories of industrial robots, industrial robot bearings are most suitable for the joints or rotating parts of industrial robots, rotary tables of machining centers, rotating parts of manipulators, precision rotary tables, medical instruments, measuring instruments, IC manufacturing devices, etc.

Features of industrial robot bearings

1. Can withstand axial, radial, overturning and other direction combined loads; 2. Thin-walled bearings; 3. High rotation positioning accuracy.

Classification of industrial robot bearings

There are mainly two types of bearings for industrial robots, one is equal-section thin-walled bearings, and the other is cross-roller bearings. In addition, there are harmonic reducer bearings, linear bearings, spherical bearings, etc., but equal-section thin-walled bearings and cross-roller bearings are mainly used.

Crossed roller bearings are cylindrical rollers or tapered rollers arranged perpendicularly to each other on a 90-degree V-groove rolling surface through a spacer block, so the crossed roller bearings can withstand multi-directional loads such as radial loads, axial loads and moment loads. The size of the inner and outer rings is miniaturized, and the ultra-thin form is close to the limit of small size, and has high rigidity, and the accuracy can reach P5, P4, P2 level. Therefore, it is suitable for the joints and rotating parts of industrial robots, the rotary table of machining centers, precision rotary tables, medical machines, calculators, military industry, IC manufacturing equipment and other equipment.
