Double row ball type Series 07

What is Double row ball type Series 07? The structure of the double row ball slewing bearing is basically the same as that of the single-row four-point contact ball slewing bearing, the difference is that the slewing bearing has two rows of rolling elements. It can bear large axial load and radial load overturning moment at the same time. The axial and radial dimensions of the double-row reducing ball slewing bearing are relatively large and the structure is tight. It is especially suitable for loading and unloading machinery such as tower cranes and truck cranes that require medium or larger diameters.

 

Zhiyuan machinery is a professional Chinese double row ball slewing bearing manufacturers and suppliers of double row ball slewing bearing, committed to the design, manufacture, production and sales of all kinds of slewing bearing. Product specifications are diverse and models are complete. The basic structure of slewing bearing slewing drive usually consists of worm, slewing bearing, shell, motor and other components. Because the core component adopts slewing bearing, it can bear axial force, radial force and tipping moment at the same time. There are many forms, but the structure is basically the same.

 

The double row ball slewing bearing has three seat rings. The steel balls and isolation blocks can be directly discharged into the upper and lower raceway. According to the force condition, the upper and lower two rows of steel balls with different diameters are arranged. This kind of open assembly is very convenient, the bearing angle of upper and lower arcs raceway is 90°, which can bear great axial force and tipping moment. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. The axial and radial dimensions of the double diameter ball slewing bearing are large and the structure is tight. It is especially suitable for tower cranes, truck cranes and other loading and unloading machinery requiring medium diameter or above.

 

Double row ball slewing bearing is widely used, construction machinery is the first application of slewing bearing is also the most widely used place, such as earthmoving machinery, excavators, stacker and retractor, grader, roller, rock drilling machinery, riding machine, etc. Other concrete machinery, lifting machinery, engineering ships, aerial work platforms and so on. In addition to all kinds of construction machinery, the application scope of double row ball slewing bearing has been gradually expanded. At present, equipment platforms such as port equipment, metallurgy equipment, wind power generation equipment and drilling platform have begun to use slewing bearing to replace the original bearing in a large range.
