A-65x PIglide HB: Hemispherical Air Bearing Friction-free, ideal for rotary motion on three axes  Clean room compatible  Low inertia  Diameter up to 300 mm  Rotatable in three directions  Load capacity to 635 kg  Tip/tilt range to ±45°  Operating pressure of 30 psi to 90 psi (207 kPa to 621 kPa)  Ideal for satellite control and simulation of weightlessness Overview The PIglide HB series with spherical air bearings makes unique positioning and simulation applications possible in the fields of research and industry. The bearings offer excellent load capacity and stiffness, and at the same time, inherent friction-free motion on three rotational axes. The spherical bearings, which are often used in research on weightlessness in satellites, are also used in systems for precision chip contacting and optical alignment. Due to the use of spherical bearings at both ends of the drive screw shaft, it is possible to build extremely stiff drive screws. This arrangement allows precision alignment of the drive screw shaft due to the motion of one spherical bearing relative to the other.
