2.General Introduction of slewing ring 

1:Three row roller type slewing bearing

Three-row roller (three-row roller slewing bearing has three seats, upper and lower and radial raceways Separate each row of rollers so that the load of each row of rollers can be accurately determined. It can bear various loads at the same time, and is the largest of the four products. The shaft, radial and radial dimensions are large, and the structure is firm. It is suitable for heavy machinery requiring larger diameters, such as wheeled excavators, wheeled cranes, marine cranes, port cranes, steel transfer platforms and large tonnage truck cranes, etc.). 

2:Double row ball type slewing bearing

Double-row ball type (double-row ball type slewing bearing has three seat rings , The steel balls and spacers can be directly discharged into the upper and lower raceways. According to the stress conditions, two rows of steel balls with different diameters are arranged. This open assembly is very convenient and can withstand large axial forces and tilting moments. , The structure is tight, suitable for loading and unloading machinery such as tower cranes and truck cranes with medium and above diameters.)
3:Single-row cross-roller type slewing bearing
Single-row cross-roller (single Row cross roller slewing ring, composed of two seat rings, compact structure, light weight, high manufacturing accuracy, small assembly gap, high installation accuracy requirements, rollers are arranged in a 1:1 cross, which can bear axial force at the same time , Tipping moment and large radial force, are widely used in lifting and transportation, construction machinery and military products.);
4:Single-row ball type slewing bearing
Single-row ball type (single-row four-point contact ball slewing bearing is composed of two seat rings, compact structure, light weight, four-point contact between the steel ball and the arc raceway, and can bear the axial force at the same time , Radial force and tipping moment. Suitable for rotary output conveyors, welding manipulators, medium and small cranes and excavators and other construction machinery can be selected).
