AirStar Separator Roll - Air Bearing

Description

This is a new AirStar Separator Roll: the AirStar part number is XB-27301 .  The outer ring is made from case hardened D2 tool steel.  It is 2 1/8" in diameter and 3" long with two pulley type grooves.  The compressed air connection is 1/8-27 NPTF.
AirStar hydrostatic separator rolls are often used for guidance and directional change of synthetic filaments, fibers, yarns, cords, and films in extrusion, spinning, drawing, draw-twisting, winding, and texturing machinery.
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
