 technology company specializing in integrating advanced oil-free compliant foil bearing
Foil bearing
Foil bearings, also known as foil-air bearings, are a type of air bearing. A shaft is supported by a compliant, spring-loaded foil journal lining. Once the shaft is spinning quickly enough, the working fluid pushes the foil away from the shaft so that there is no more contact...

Turbocharger
A turbocharger, or turbo , from the Greek "τύρβη" is a centrifugal compressor powered by a turbine that is driven by an engine's exhaust gases. Its benefit lies with the compressor increasing the mass of air entering the engine , thereby resulting in greater performance...

s, compressors
Gas compressor
A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume.Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas...

Heshmat is a fellow in both the American Society of Mechanical Engineers , and the Society of Tribologists and Lubrication Engineers....

  and three other principals, James F. Walton II, Melissa Heshmat and Michael J. Tomaszewski. The company vision called for developing a new class of oil-free, high-speed rotating machinery. Oil-free air or process gases are essential for pharmaceutical, food and beverage processing, in medical equipment or devices and many industrial processes. The company initially conducted research and development programs for the United States Department of Defense

Magnetic bearing
A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact; for example, they can levitate a rotating shaft and permit relative motion with very low friction and no mechanical wear...

s, auxiliary or backup bearings and advanced seals.

The company has applied its oil-free bearing and seal technologies to rotating machinery systems with both domestic aerospace and major international companies. Developed oil-free systems have included motor driven air compressors for industrial use, cryogenic turboexpanders for generation of liquid oxygen and nitrogen, motor driven air blowers for automotive fuel cell
Fuel cell
A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel, but hydrocarbons such as natural gas and alcohols like methanol are sometimes used...

 and more recently microturbine generators for distributed electricity generation using either natural gas or a variety of renewable energy sources. While conducting many of these research programs and working to apply the technology to product, alternative bearing coatings and test machine products have resulted. New high temperature, long life and low friction coefficient coatings were developed to support the bearing product. Also a special high precision Tribometer
