Slewing Bearing Type
- Sep 06, 2018 -

Three rows of combined roller slewing bearings

The three-row roller slewing bearing has three races, the upper and lower and the radial raceways are separated, so that the load of each row of rollers can be accurately determined, and can bear various loads at the same time, which is the bearing capacity of four products. The largest one, with large shaft and radial dimensions, is particularly suitable for heavy machinery requiring large diameters, such as bucket wheel excavators, wheeled cranes, marine cranes, ladle slewing and large tonnage truck cranes. on.

Double row angular contact ball slewing bearing

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. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. The double volleyball type slewing ring has large axial and radial dimensions and a solid structure. It is especially suitable for loading and unloading machines such as tower cranes and truck cranes that require medium and large diameters.

Single row cross roller slewing bearing

Single row cross roller type slewing ring, consisting of two races, compact structure, light weight, high manufacturing precision, small assembly clearance, high requirements for installation accuracy, roller 1:1 cross arrangement, can simultaneously bear axial Force, large radial force and tipping moment. It is widely used in lifting transportation, construction machinery and military products.

Single row four point contact ball slewing bearing

The single-row four-point contact ball bearing slewing ring consists of two races. It is compact in structure, light in weight, and the steel ball is in contact with the arc track at four points. It can simultaneously 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.
