Slewing bearings comprise an inner ring and an outer ring, one of which usually incorporates a gear. Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components. The bearing raceways, in conjunction with the rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination, and in any direction.

According to the stress conditions, the upper and lower rows of steel balls with different diameters are arranged. This open type assembly is very convenient. The bearing angle of the upper and lower circular arc raceways is 90 °, which can withstand large axial force and tipping moment.
