What is a Rotor Delevitation System?


The Rotor Delevitation System® (RDS®) is an advanced auxiliary bearing design. The RDS is comprised of a dry lubricated bushing mounted in a stator component and a special rotor component designed to reduce and dissipate heat during contact and coast-down.

For small machines, the radial and axial bushings are full 360-degree components; this technology is typically utilized in turboexpanders and air compressors. For larger machines, such as centrifugal gas compressors and turbines, a tilting pad bearing technology is used.

This design provides adjustable bearing stiffness and damping performance for rotor stability and imparted load control. Unlike other auxiliary bearings, the RDS is capable of operating in harsh environments, including those with arduous process fluids or elevated temperatures.
