Slewing bearings, also known as slewing bearings, are large bearings that can withstand large axial loads, radial loads and overturning moments at the same time. Slewing bearings are generally equipped with mounting holes, internal gears or external gears, lubrication holes and sealing devices, which can make the mainframe structure design compact, reliable, and convenient maintenance.
Slewing bearings are available with four-point contact ball bearings without gear, external gear and internal gear, double-row angular contact ball bearings, cross-cylindrical roller bearings, crossed-tapered roller bearings and three-row cylindrical roller combination bearings, etc. Structure type. The four-point contact ball bearing has a higher static load capacity; the cross-cylindrical roller bearing has a higher dynamic load capacity; the crossed-tapered roller bearing allows the bearing to have a greater support rigidity and higher rotation through the pre-energizer. Accuracy.
Slewing bearings are widely used in large rotary devices such as lifting machinery, mining machinery, construction machinery, port machinery, marine machinery, and high-precision radar machinery and missile launchers.
Slewing Rings - Single Row Four Point Contact Ball Slewing Rings (01 Series)
Structural features. Performance.
The single-row four-point contact ball slewing bearing is composed of two seat rings. The structure is compact and light in weight. The steel ball and the arc raceway are in contact at four points and can simultaneously bear axial force, radial force and tilting moment. Rotary conveyor welding manipulators can be selected for construction machinery such as small and medium sized cranes and excavators.
Slewing Rings - Single Row Cross Roller Slewing Rings (HS Series)
Structural features. Performance.
Single-row four-point contact ball type slewing bearing consists of two seats, compact structure, light weight, steel ball and four arc contact race, can simultaneously withstand the axial force, radial force and tilting moment, rotary type Conveyors, welding manipulators, small and medium-sized cranes and excavators and other construction machinery can be selected.
