High Precision in Any Aspect with PI's New Rotary Air Bearing Series

(Nanowerk News) PI (Physik Instrumente), a leader in precision motion control solutions, announces the new A-62x PIglide series of rotary air bearing stages. Air-bearings have no rolling or sliding elements and deliver frictionless, non-contact motion, resulting in negligible reversal error, better straightness, wobble, eccentricity and velocity stability ideal prerequisites for high-end industrial applications such as inspection, metrology, calibration, and scanning.

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. The PIglide RM series of motorized rotary air bearing stages are a complete positioning solution designed for accuracy, precision, high stiffness, and ease of use. Featuring high performance, low-cogging frameless slotless torque motors and optical encoders, these stages can be used in any orientation. Various options can be combined to create a solution ideal for point-to-point indexing or constant velocity scanning. The PIglide RM rotary positioners provide velocity to 2500rpm and extreme precision with radial motion errors as low as 50nm, axial runout as low as 50nm, and tilt errors down to 0.3arc-sec. Coupled with no required maintenance or lubrication, these rotary positioners have a virtually unlimited life.
