Slewing bearing is a kind of large bearing which can bear the combined load, and can bear large axial, radial load and overturning moment at the same time.
Slewing bearing is widely used in the real industry, known as the "machine joint", this is between the two objects required for relative rotary movement, and also need to bear the axial force, radial force and torque required to turn tilting machinery important transmission parts. With the rapid development of the machinery industry, slewing bearings have been widely used in ship equipment, construction machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.
Type:
01 series
Single row four point contact ball slewing bearing
It consists of two rings, compact, light weight, steel ball and arc raceway four points contact, which can bear axial force, radial force and overturning moment. Rotary conveyors, welding machines, small and medium-sized cranes and excavators and other construction machinery are available.
02 series
Double row reducer ball slewing bearing
The double volleyball type slewing bearing has three seat rings, and the steel ball and the isolating block can be directly discharged into the upper and the lower rolling paths. According to the force condition, the two rows of steel balls with different diameters are arranged. This open assembly is very convenient, upper and lower arc raceway bearing angle is 90 degrees, can bear large axial force and overturning moment. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. Double row radial ball slewing bearings are of relatively large axial and radial sizes, and the structure is tight. The utility model is especially suitable for tower cranes, automobile cranes and other loading and unloading machines requiring medium or more diameters.
11 series
Single row cross roller slewing bearing
Hjw, composed of two seats, compact structure, light weight, high manufacturing precision, assembly gap is small, the installation of high precision roller for 1:1 cross arrangement, can withstand the axial force, overturning moment and large radial force, is widely used in hoisting and transportation. Engineering machinery and military products.
13 series
Three row roller slewing bearing
The three row roller slewing bearing has three rings, the upper and lower and the radial raceways separate, so that the load of each row of rollers can be accurately determined. At the same time can withstand all kinds of load bearing capacity of four kinds of products in one of the largest, the axial and radial dimensions are larger, firm structure, especially suitable for heavy machinery with larger diameter, such as bucket wheel excavators, wheeled crane, crane, port crane, steel water table and large tonnage truck cranes.
Light series slewing bearing
Light slewing bearing
The light slewing bearing has the same structural form as the ordinary slewing bearing, which is light in weight and flexible in rotation. Widely used in food machinery, filling machinery, environmental protection machinery and other fields.
HS series
Single row four point contact ball slewing bearing
The single row four point contact ball slewing bearing consists of two rings. The structure is compact, and the steel ball contacts the arc raceway at four points. Mainly used in automobile cranes, tower cranes, excavators, pile drivers, engineering vehicles, radar scanning equipment to withstand overturning moment, vertical axial force, horizontal tilt force on the machine.
HJ series
Single row cross roller slewing bearing
Hjw, composed of two seats, compact structure, high manufacturing precision, assembly gap is small, the installation of high precision roller for 1:1 cross arrangement, can withstand the axial force, overturning moment and large radial force, which is widely used in transportation, engineering machinery and military product.
