Product Description
Heavy-Duty Construction Machinery Turntable Bearing 12-50 2240/2-06520 Large Size Swing Bearing
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 high requirement 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.
Three row roller slewing bearing
Three row roller bearing able to bear all kinds of loads at the same time, it is the largest one of the four structural products with large axle and radial dimensions and firm structure. Especially suitable for heavy machinery requiring larger diameter, such as bucket wheel stacker and reclaimer, wheel crane, marine crane, port crane, ladle turret,large tonnage truck crane,heavy machinery and so on.
