Four-point contact ball slewing turntable bearings
consist of two ring seats. Compact structure, light weight, steel ball and arc track contact at four points, can bear axial force,radial force and overturning moment at the same time, has strong dynamic load.


Single row cross roller slewing bearing
Composed of two or three rings. compact structure, light weight, high manufacturing accuracy, small assembly gap and highrequirement for installation accuracy. Rollers are 1:1 cross-arranged. Can be bear axial force, overturning moment and large radial force at the same time,and widely used in lifting transportation,construction machinery and precesion products.



Double row ball slewing bearings
This kind of bearings can support high static loads with simple structures. They are mainly used in situations with variation load position and direction and continuously rotating. Main applications of this kind of bearings are deck hoisting, mining and material handling etc.
