Double Row Different Diameter Ball Slewing Bearing

Product description of double row reducing ball slewing bearing

Double-row reducing ball slewing bearings are usually composed of four main parts: inner ring, outer ring, rolling elements and spacer blocks. Because the core component adopts slewing bearing, it can bear axial force and radial force at the same time. There are many forms, but the structure is basically the same.
The double-row reducing ball slewing bearing has three races, and the steel balls and spacers can be directly discharged into the upper and lower races. According to the stress conditions, two rows of steel balls with different diameters are arranged. This kind of open assembly is very convenient. The load-bearing angle of the upper and lower arc raceways is 90°, which can bear larger axial force and overturning moment. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. The double-row reducing ball slewing bearing has larger axial and radial dimensions and compact structure. It is particularly suitable for loading and unloading machinery that requires medium or larger diameters, such as tower cranes and truck cranes.
