Lower Inertia Spherical Air Bearing. Additional facts http://www.pi-united states of america.us/weblog/employing-spherical-air-bearings-in-satellite-tests/ These bearings are generally utilised for zero-gravity simulation in satellite investigate and tests.
Other apps include precision optical alignment, precision spindle alignment and semiconductor chip bonding.
PI spherical air bearings present all a few rotational degrees of freedom with pretty much frictionless motion, combining significant load potential and stiffness
