Airstar Bearings

AirStar is a supplier of premium hydrostatic separator rolls often used on synthetic filament, fiber, film, and yarn production equipment. The AirStar Separator Roll (sometimes called an air bearing) is a hydrostatic bearing. The rotating roll and stationary shaft are separated by a thin film of pressurized air, which is supplied through the hollow shaft. The unique carbon-against-carbon construction used within the AirStar bearing tolerates intermittent overloads from excessive wraps, tension, vibration, or transient loss of air supply. The Result is a superior separator roll with the following benefits. • Extremely long bearing life • Very low friction and bearing torque • Ability to operate at very high speeds • Ability to operate in high temperature environments • Ability to operate in adverse chemical environments
