Various embodiments of the present technology generally relate to precise rotary motion control systems. More specifically, some embodiments relate to systems, methods, and means for providing pressure to a non-contact rotary system. In some embodiments, the rotary system comprises a rotary shaft that can rotate three hundred and sixty degrees continuously. In order for the rotary system to be entirely non-contact with any surfaces of surrounding components or housing, pressure must be supplied to a rotary air bearing that floats the rotary unit above a surface. In some examples, the bottom air bearing is a vacuum preloaded (VPL) air bearing. As such, the VPL air bearing requires a supply of positive pressure and a supply of negative pressure to stabilize the rotary unit. The present technology provides a mechanism for providing pneumatic air to the air bearing without a physical connection to the rotary shaft or air bearing.
