Double row angular contact ball slewing ring bearings
Slewing bearing has three seat double, steel ball and isolation block can be directly

discharged into rolling up and down,Roller Bearing according to the stress state, arranged up and down two

different diameter of steel ball.
This open assembly is very convenient, and arc raceway of bearing Angle is 90 °, can bear a

large axial force and overturning moment. When the axial force of the radial force is greater

than 0.1 times the race must be specially designed. Slewing bearing pairs of axial and radial

size is larger, solid structure, especially suitable for the requirements above medium

diameter of tower crane, truck crane loading and unloading machinery, etc.
Single row cross roller slewing bearings
Single row cross 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 larger axial force and radial

force and overturning moment. Is widely used in hoisting, transportation, engineering

machinery and military products.
Single row four-point contact ball slewing ring bearings
Single row four-point contact ball bearing slewing bearing is composed of two seat, compact

structure, light weight, rolls four point contact ball and circular arc, can withstand the

axial force and radial force and overturning moment. Rotary conveyor, welding CaoZuoJi, small

and medium-sized crane and excavators and other construction machinery are optional.
