Slewing bearing model and features

1. Single row four point contact ball type slewing ring (01 series)

The single-row four-point contact ball slewing ring consists of two races. It is compact and lightweight. The steel ball is in contact with the arc track at four points and can withstand axial force, radial force and tipping moment. Construction machinery such as rotary conveyors, welding operators, small and medium-sized cranes and excavators are available.

2, double row ball slewing ring (02 series)

The double volleyball slewing bearing has three races. The steel ball and the spacer block can be directly discharged into the upper and lower raceways. According to the force condition, two rows of steel balls with different diameters are arranged. This open assembly is very convenient, the upper and lower circular races have a bearing angle of 90° and can withstand large axial forces and tipping moments. The axial and radial dimensions of the bearing are relatively large and the structure is fastened. It is especially suitable for loading and unloading machines such as tower cranes and truck cranes that require medium and large diameters.

3. Single row cross roller type slewing ring (11 series)

Single row cross roller type slewing ring consists of two races. It is compact in structure, light in weight, high in manufacturing precision, small in assembly clearance, high in installation accuracy, and 1:1 cross-arrangement of rollers. Force, tipping moment and large radial force are widely used in hoisting transport, construction machinery and military products.

4, three rows of roller slewing bearings (13 series)

The three-row roller type slewing bearing has three races, and the upper and lower and the radial raceways are separated, so that the load of each row of rollers can be accurately determined. It can withstand various loads at the same time. It is the most load-bearing type among the four products. It has large shaft and radial dimensions and is firm in structure. It is especially suitable for heavy machinery requiring large diameter, such as bucket wheel excavator and wheel. Cranes, marine cranes, port cranes, steel running tables and large tonnage truck cranes.
