Industrial robot bearings mainly include thin-walled bearings, cross cylindrical roller bearings, harmonic reducer bearings and joint bearings, but mainly cross roller bearings.Structural characteristics of cross roller bearings in welding robot joints: cylindrical rollers are arranged vertically and cross each other in the inner and outer circular raceways of the bearings, and a single bearing can bear the common load of radial force, bidirectional axial force and overturning moment at the same time.Large bearing capacity, good rigidity, high rotation accuracy, easy installation, save space, reduce weight, significantly reduce friction, and provide good rotation accuracy.Make the mainframe light, miniaturization become possible.

Bearing is one of the important and key parts of the industrial robot. Its localization is related to the overall economic competitiveness of the domestic robot industry.The robot industry continuous development of social demand in China, is an urgent need to develop industrial robots form a complete set of bearing development and industrialization of key information technology innovation research and development, to ensure the bearing performance indicators have reached the international advanced socialist culture analysis level under the premise of production and business operation can reduce the product cost, in order to further establish and improve the industrial robot industry structure system,We will strive to cultivate 3 ~ 5 leading enterprises with international trade competitiveness and 8 ~ 10 supporting service industrial clusters in 2020, so as to improve the market competitiveness of domestic robots and promote the rapid development of artificial intelligence equipment industry.

The continuous development of modern enterprise industrial robots has tended to be lightweight, which requires us to support the relevant bearings with a more lightweight structure in China.Attributed to bearing in technology limited installation space can meet the social host industrial robot, the precision and the carrying capacity of bearing stiffness and friction torque performance requirements and selection standards of general bearing it is difficult to satisfy the teaching requirements, students pursuing shape and thin wall bearing limit of size, with light weight, small size, high precision, long life and other excellent properties,Can achieve a good solution to this important problem.

KOYO Special bearings for industrial robots mainly include uniform section thin-walled bearings, thin-walled cross cylindrical roller bearings, RV reducer bearings and harmonic reducer flexible bearings.As one of the key components of industrial robots, industrial robot bearings mainly include two kinds of bearings for industrial robots, one is the thin-wall bearing of equal section, the other is the cross cross cylindrical roller bearing.There are harmonic reducer bearings, linear bearings, joint bearings, but mainly the first two bearings.
