Slewing rings may be small, but they help do some of the largest jobs in the business. From swing arm rotation on cranes to the platform on a wind turbine, slewing rings are an integral part of many machinated processes. 

silver thin slewing rings 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.

slewing rings are a cost-effective, performance-enhancement option for rotary devices carrying heavy loads. Slewing rings have a compact design and can be manufactured without teeth, with internal or external teeth, with balls, and/or with rollers. Slewing rings are used across industries for several applications, including construction equipment, waste water treatment machinery, wind-power generation, drilling equipment, logging industry machines, mining equipment, revolving grabbers and winches, and steering applications. Slew rings are a critical component in industries such as aerospace, forestry, power, automotive, military, manufacturing, medical, robotics, nautical, and surveillance.
