GERB Vibration Control System, Inc., GERB's U. S. A. subsidiary, was founded in Chicago in 1988. Since 2000, GERB USA has been conveniently located in Lisle, a western suburb of Chicago.

GERB USA is responsible for the North American market, also serving customers in Canada and Mexico. We design and supply vibration control systems based upon helical steel springs and viscous fluid dampers, especially for the metalworking industry, focusing on forging and press applications, for the electric power industry, and for the vibration or seismic protection of buildings, structures and rail track beds.

For more than 20 years, we have worked successfully with LASCO Engineering, Detroit, (formerly Letts Equipment Division) to elastically support forging hammers and presses. In 2000, we joined forces with Kinetics Noise Control, Columbus, Ohio, to market spring-supported protection for buildings and rail track beds.

Other spring supported applications include measurement and test equipment, automotive shredders, centrifuges and fans, as well as viscous fluid dampers for piping in power plants and other industrial applications.

GERB USA offers the following services:

• Consultation, concept design, and preparation of machine foundation drawings, including static and dynamic calculations.
• Design and supply of spring elements and VISCODAMPERS® to elastically support machines, equipment and structures.
• Installation supervision.
