Description
Slewing bearings
To "slew" means to turn without change of place; a "slewing"
bearing 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.
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
"halves" 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.
