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 raceways. According to the stress conditions, two rows of steel balls with different diameters are arranged. This kind of open assembly is very convenient. The bearing angles of the upper and lower arc raceways are all 90 °, which can bear large axial force and overturning moment. When the radial force is greater than 0.1 times of the axial force, the raceway must be specially designed. The axial and radial dimensions of the double volleyball slewing bearing are relatively large, and the structure is tight. It is especially suitable for tower crane, truck crane and other loading and unloading machinery requiring medium or above diameter.There are three types of products:No teeth(020),Outer teeth(021.002) and Inner teeth(023.024). This product is a tight structure,large axial radial dimensions slewing bearing, it is also a loading unloading machinery slewing bearing.What is more ,it is a No teeth,Inner teeth and Outer teeth slewing ring.

Many people don't know. In fact, the application fields of slewing bearings and slewing bearings can be described as high and complete. On our well-known key heavy-duty equipment, we can see huge slewing bearings and slewing bearings, up to 300mm to 10 meters. The carrying capacity ranges from several hundred tons to thousands of tons, and the turning diameter is more than 100 meters. It reflects the throughput and lifting capacity of a port. Among them, the current one is the most, and the slewing bearing and slewing bearing capacity are all obvious.

The double row ball type slewing bearing has large axial and radial dimensions and a solid structure, and is particularly suitable for loading and unloading machines such as tower cranes and truck cranes that require medium and large diameters.
