Linear Servo Motor Air Bearing Stage has 38 mm overall height.

Press Release Summary:



Floating on air cushion without rollers or sliding components, frictionless PIglide A-141 delivers vibration-free motion with velocity stability and zero mechanical component wear. Miniature linear positioner has preloaded air bearings and integral optical linear encoder. Latter provides position information down to 20 nm resolution. Smooth motion, without any cogging or attractive forces, is provided by ironless linear motors, which reach velocities up to 0.5 m/sec and acceleration to .75 g.



Original Press Release:



PI Introduces Its Miniature Linear Servo Motor Air Bearing Stage



Auburn, MA – PI (Physik Instrumente) L.P., a leading developer and manufacturer of precision motion systems and solutions, recently released the A-141 miniature air bearing linear positioner, the newest member of the frictionless PIglide family of air bearing stages. Air bearings provide advantages over mechanical bearings when vibration-free motion is required, highly constant velocity control is crucial, and when angular repeatability and geometric performance must be optimal.



Why Use Air Bearings?

Designed to float on a cushion of air without rollers or sliding components, air bearing positioners deliver extremely precise and vibration-free motion, with excellent velocity stability, and zero wear of mechanical components, which are ideal for high-end industrial inspection and manufacturing operations. Air bearing stages are ideally suited for many high precision applications, such as metrology, photonics alignment, semiconductor, flat panel display, precision scanning applications, and cleanroom applications.

Linear Motor and Encoder Deliver Ultra-Precision, High Speed, and Acceleration

The compact A-141 features preloaded air bearings and an integral optical linear encoder. With an overall height of only 38mm, it is one of the smallest air bearing stages on the market and is well-suited to fit in small spaces. There are no electrical cables to manage. Smooth motion with no cogging or attractive forces is provided by ironless linear motors; position information down to 20nm resolution comes from integrated linear encoders. The powerful linear motors reach velocities up to 0.5m/sec and acceleration to .75g.
