Spherical Air Bearings for Satellite Attitude Control Test / Zero Gravity Simulation
3-DOF Low Inertia Spherical Air Bearings are often used for satellite attitude control testing and zero-gravity simulation. Other applications include precision optical alignment, precision spindle alignment and semiconductor chip bonding. PI spherical air bearings provide all three rotational degrees of freedom with virtually frictionless motion, combining high load capacity and stiffness. Read more here .
