The A-62x PIglide series of rotary air bearing stages

Release Time：18 May,2017

PI (Physik Instrumente) L.P., Air Bearings and Piezo Precision Motion The A-62x PIglide series of rotary air bearing stages from Physik Instrumente LP have no rolling or sliding elements and deliver frictionless, noncontact motion.&#160; <img src="http://www.bearing.com.cn/RecommendedCompany/國(guó)1.jpg"> Featuring high-performance, low-cogging frameless slotless torque motors and optical encoders, the 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 2500 rpm and extreme precision with radial motion errors as low as ±50 nm, axial runout as low as ±50 nm and tilt errors down to 0.3 arc-s. Coupled with no required maintenance or lubrication, the rotary positioners have a virtually unlimited life.&#160; Resulting in negligible reversal error, better straightness, wobble, eccentricity and velocity stability, the devices are ideal for high-end industrial applications such as inspection, metrology, calibration and scanning.
