Whether your challenge is precision, speed or environment, we can offer unmatched experience.
Our Air Bushings are designed to make Air Bearing technology readily available to engineers with pre-existing designs based on round shaft guides.
Air Bushings are, essentially, a tube of Porous Media. Applying an air pressure of 0.41 MPa creates a 4 µm layer of air between the Air Bushing and a shaft. The Air Bushing is designed so that a self centering force is created by the air flow, allowing for true 360° non-contact motion on round shafting. The paralleling force over the length of the bushing centers the shaft naturally, creating precise, non-contact motion in one axis.
The resulting frictionless motion eliminates the heat and vibration commonly associated with roller contact or recirculating ball linear way arrangements. The self centering force also allows for higher than standard rotational speeds.
