Linear Air Bearings for Precision Motion
PI Nelson Air's linear air bearings and air bearing slides provide smooth, accurate linear and multi-axis motion. You can purchase air bearing component parts for passive systems, build your own air bearing stage, or buy a complete air bearing stage with integrated motor, encoder and high-performance motion controller.
