The light slewing bearing has the same structure with four point contact ball slewing bearing, but the weight is light and could be used for some light type machinery applications.
The light slewing bearing ring has been widely used in many applications:
A slewing bearing ring is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, or the wind-facing platform of a horizontal-axis windmill. And many food machinery, packing machinery and environmental machinery etc.
Light type slewing bearing has its own features compared with normal slewing bearing,as its weight is lighter compared to other type slewing bearing. So it can be used in many industrial categories.
