The single row four point contact ball slewing bearing is composed of two seat rings, which is compact in structure and light in weight. The steel ball is in four point contact with the circular arc raceway, and can bear the axial force, radial force and tipping moment at the same time. Rotary conveyors, welding operators, small and medium-sized cranes, excavators and other engineering machinery can be selected.

Consist of two ring seats. Compact structure, light weight, steel ball and arc track contact at four points, can bear axial force, radial force and overturning moment at the same time, has strong dynamic load.

2.Changzhou Aoxuan Heavy Bearing Co., Ltd. is located in the beautiful and rich Yangtze River Delta region, with convenient transportation and obvious industrial advantages. The company covers an area of 33000 square meters, with a building area of 23000 square meters. It has more than 150 sets of production and processing equipment and testing equipment. The main products are: slewing ring, slewing drive and precision grade cross roller bearing. It is mainly used in engineering machinery, industrial robots, port machinery, construction machinery, truck cranes, metallurgical machinery, single and double axis tracking systems for solar photovoltaic power generation systems and small wind power stations.

3. Slewing bearing is also known as rotary bearing and slewing bearing. Slewing bearing is widely used in real industry and is called "machine joint" by people. It is an important transmission component for machinery that needs to make relative rotary motion between two objects, and also needs to bear axial force, radial force and tipping torque. Its main role is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotary accuracy. The rotation speed of slewing ring is lower than that of general bearings.

According to the different friction properties of moving elements, slewing bearings can be divided into rolling bearings and sliding bearings. The rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial size, vibration and noise are larger, and its price is higher. Its basic structure is generally composed of four parts: outer ring, inner ring, rolling element and cage. According to the shape of rolling element, rolling bearings are divided into ball bearings and roller bearings.

The application of this type of bearing is common in the structural composition of large construction machinery, such as earthwork machinery, excavator, stacker reclaimer, grader, roller, rock drilling machinery, roadheader, etc. Others include concrete machinery, hoisting machinery, engineering ships, aerial work platforms, etc.

In addition to various engineering machinery, the application scope of slewing ring has been gradually expanded. At present, similar equipment platforms such as port equipment, metallurgical equipment, wind power generation equipment, drilling platforms, etc. have begun to use slewing ring to replace the original bearing in a large range. In practical application, the specification, size, accuracy and other conditions of the bearing shall be selected according to the use position, use conditions and environment of the bearing. The suitable bearing can effectively ensure the life of the slewing ring, which is the premise of the life and feasibility of the slewing ring.
