Squeeze film dampers are used to shift critical speeds and/or to increase the dynamic stability of the rotor-bearing system. One of the key features introduced by a squeeze film damper is the introduction of support flexibility and damping in the bearing/support structure. This translates to lower transmitted forces and longer bearing life, particularly for machinery that are designed to operate at super critical speeds. Our patented, integral centering spring-squeeze film dampers provide an accurate and simple approach to new and retrofit installations requiring a squeeze film damper. Our design, optimized with finite element methods and manufactured with wire EDM process, offers many advantages over other designs such as squirrel-cage or "O" ring squeeze film dampers.

Key Benefits

Bearing Plus's integral centering spring squeeze film damper is the only commercially available damper design which provides:

	Precise stiffness and damping to match rotordynamic requirements
	Minimal space requirement
	Shaft centering ability
	Split configuration for compliance with API specifications dictating split bearings configuration

Unlike "O" ring dampers, our design takes thrust loading and offers linear stiffness unaffected by temperature or age. And unlike squirrel cage dampers, our dampers maintain parallelism between the damper journal and housing.
