AUBURN, Mass., April 2, 2020 /PRNewswire-PRWeb/ — PI (Physik Instrumente), a leader in precision motion control and nanopositioning solutions, announces a new large motorized rotary air bearing added to its existing families of PIglide air bearing rotary stages.

Why Air Bearings
Air-bearings have no rolling or sliding elements and deliver frictionless, non-contact motion, resulting in negligible reversal error, better flatness, and minimal wobble and eccentricity. All these are ideal prerequisites for applications such as inspection and metrology, calibration, and scanning of high-end parts (i.e., infrared and precision optics, turbine blades, shafts and bearings) in industries like aerospace, aircraft, automotive, semiconductors and photonics.

Nanopositioning in Any Aspect
Air bearings replace mechanical contact by a thin film of air which is completely frictionless, resulting in no breakaway stiction or drag friction during operation. Featuring high performance, low-cogging frameless slotless torque motors and optical encoders, these stages can be used in any orientation. The A-688 is customizable with options to create a solution for point-to-point indexing or constant velocity scanning. Coupled with no required maintenance or lubrication, these rotary positioners have a virtually unlimited life.
