PI (Physik Instrumente) L.P. Hemispherical Air Bearing, PIglide HB A-65x

The PIglide HB series spherical air bearing enables unique positioning and simulation applications in both research and industrial fields. These bearings provide excellent load capacity and stiffness while allowing three axes of inherently frictionless rotational motion. Commonly used for zero-g satellite research, spherical bearings are also used in systems for precision chip bonding and optical alignment. Extremely rigid spindles can be made using a spherical bearing at each end of the spindle shaft. This arrangement also allows precision alignment of the spindle shaft on the fly by moving one spherical bearing relative to the other. Sizes from 50mm to 300mm Diameter Load to 635kg Tilt to ±45 degrees Zero Stiction, Low Inertia for Simulation Table Top and Floor Mount Pedestals Available
