Principle of crossed Roller slewing bearings: Cross rollers are arranged at right angles to each other at intervals between the inner and outer rings of the bearing. They can simultaneously support loads from all directions (such as axial, thrust, or momentum loads). The internal structure of the crossed roller bearing adopts the rollers arranged at 90 ° to cross each other vertically. Spacers or spacers are installed between the rollers, which can prevent the inclination of the rollers and friction between the rollers.

Crossed roller slewing bearing, is composed of two seat, compact structure, light weight, high accuracy of manufacture, assembly, small gap of installation accuracy requirement is high, the roller of 1:1 cross arranged, can bear axial force at the same time, the overturning moment and large radial force, is widely used in hoisting, transportation, engineering machinery and military products.There are three types of products:No teeth(110),Outer teeth(111,112) and Inner teeth(113,114). So, this product is a light weight high accuracy crossed roller slewing bearing and a two seat,compact structure slewing bearing.

In addition, one side of the roller does not contact or lock up. At the same time, because the inner and outer diameters are divided, the gap can be adjusted. Even if a preload is applied, a high-precision rotary motion can be obtained.This product is a high-precision rotary motion slewing bearing. Crossed roller bearings, from the perspective of external structure, there are inner ring split type, outer ring split type, inner and outer ring integrated type. In terms of internal structure, there are roller type and metal window type cage type. Therefore, it is widely used in a variety of occasions: joint parts or rotating parts of industrial robots, rotating tables of machining centers, rotating parts of manipulators, precision rotating tables, medical instruments, measuring instruments, IC manufacturing devices, etc.It is a widely used measuring instruments slewing ring and a slewing ring for rotating tables,manufacturing devices .
