Abstract: A system for positioning, a stage system, a lithographic apparatus, a method for positioning and a method for manufacturing a device in which use is made of a stage system. The stage system has a plurality of air bearing devices. Each air bearing device has: a gas bearing body which has a free surface, a primary channel which extends through the bearing body and has an inlet opening in the free surface, and a secondary channel system which extends through the bearing body and which has a plurality of discharge openings in the free surface. The flow resistance in the secondary channel system can be higher than the flow resistance in the primary channel.
