SK60 SK60-5 SK60-6 Excavator Slewing Bearing for Kobelco

A slewing bearing or slew[ing] 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, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. (To “slew” means to turn without change of place.)
