LYHY slewing ring bearings Three-row roller slewing bearing combination

Slewing ring bearings

Three-row roller slewing ring has three seat down and radial raceways separately from each other, so that each row roller load can be determined exactly, can withstand all kinds of loads, is the carrying capacity of the four products the largest one, axial and radial dimensions are larger firm structure, particularly cross roller bearings‍ for applications that require larger diameter heavy machinery, such as bucket wheel excavators, wheeled cranes, ship cranes, ladle turret and large-tonnage truck cranes and other machinery on.

5.2 double row angular contact ball slewing ring bearings

Double row slewing bearing has three seat, ball and isolation block can be directly discharged into the upper and lower raceway, according to the situation by force, arranged up and down two rows of balls of different diameters.

This assembly is very convenient, carrying angle of both the upper and lower circular raceway is 90 °, can withstand large axial forces and tilting moments. When the axial force is greater than 0.1 times the radial force to be specially designed raceway. Double row slewing bearing axial, radial size was high precision bearings‍ relatively large, solid structure, particularly suitable to the requirements of the above average diameter of tower cranes, truck cranes and other handling machinery.

5.3 Single-row cross roller slewing ring bearings

Single row cross roller slewing ring, consisting of two races, compact, light weight, high manufacturing precision, small assembly space for installation high precision roller 1: a cross arrangement, can withstand axial force, greater radial force and tilting moment. Is widely used in material handling, construction machinery and military products.

5.4 Single-row four point contact ball slewing ring bearings

Single-row four-point contact ball taper roller bearing‍ bearing slewing ring composed by two seats, compact, light weight, and circular raceway ball four point contact, can withstand the axial force, radial force and tilting moment. Rotary conveyors, welding operation machine, small cranes and excavators and other construction machinery can be selected.
