Slewing Ring 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.
Slewing bearings offer a wide variety of solutions for the most demanding specifications in a variety of applications, including:
Aerospace and defense
Oil & gas
Semiconductor manufacturing equipment. .
