PIglide HB series spherical air bearings range in size from 50mm up to 300mm and can carry payloads from less than 10kg up to 635kg when supplied with compressed air at 80 psi. This wide range of sizes offers a solution for nearly any small satellite, from 1U picosatellites up to half-ton minisatellites.
The moving element of the PIglide HB spherical air bearing is made as lightweight as possible so as to reduce moving mass and moment of inertia. This helps ensure that the test system simulates the actual satellite behavior and characteristics as closely as possible.
The spherical air bearing is often used with a pedestal mount to raise the test platform off the ground and to provide clearance for the satellite under test to rotate and tilt freely.
