Ball Slewing Rings

single row

This type of slewing ring is composed of one inner ring, one outer ring, steel balls, and spacer retainers. It has a relatively compact structure, lightweight, four-point contact between the steel ball and the arc raceway, and can simultaneously bear axial and radial forces. Compared with the cross roller slewing bearing, its characteristic is that the steel balls and the raceways are in four-point contact, so its rotation is more flexible. However, its load-carrying capacity and accuracy are not as good as the cross roller slewing ring.
