?
A slewing bearing or slewing?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 & quot;slew& quot; means to turn without change of place.)
Compared to other rolling-element bearings, slewing bearings are thin in section and are often made in diameters of a metre or more; the slewing bearings on the [Falkirk Wheel] are 4 metres diameter and fit over a 3.5 metre axle. Slewing bearings resemble oversize aircraft control surface bearings.
Slewing bearings often use two rows of rolling elements. They often use three [race] elements, such as an inner ring and two outer ring & quot;halves& quot; that clamp together axially.
Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.
As for other bearings that reciprocate, rather than rotating continuously, lubrication can be difficult. The [oil wedge] built up in a continuously rotating bearing is disrupted by the stop start motion of slewing. Instead, a [hydrostatic bearing] with pumped oil flow may be used.
