Introduction
The slew ring bearing is a rotational rolling-element
bearing that supports the heavy but slow-turning
upper structure. They often use three race elements,
such as an inner ring and two outer ring halves that
clamp together axially. Slew ring bearings are made
with gear teeth integral with the inner or outer race,
used to drive the platform relative to the base.
