ABL1500 linear air bearing stage

active preload for excellent positioning

Aerotech Ltd

The ABL1500 air bearing linear positioning stage features active air preload, direct drive zero-cogging servomotors and sub-micron linear encoders for high throughput scanning and inspection applications dealing with high resolution microstructures. The air preload is applied and averaged across the entire bearing surface resulting in excellent vertical and horizontal stiffness for a superior pitch, yaw, roll, straightness and flatness performance, even under heavy load conditions. With virtually zero friction, the working life is extended, and inherently minimal maintenance results in low overall cost of ownership.
