Summary:A dead-shaft roller having a shaft and a roll with a fluid circulation passage therein, and at least two bearings support the roll on the shaft. A rotary union is positioned at least one end of the roll, possibly both. The rotary union has a rotatable sleeve and a non-rotating sleeve. The rotatable sleeve has a fluid conducting path therein, such that the fluid conducting path is in fluid communication with the fluid circulation passage in the roll. The non-rotating sleeve is positioned adjacent and internal to the rotatable sleeve. The non-rotating sleeve has a first fluid port therein such that the fluid conducting path is in fluid communication with the first fluid port at a first fluid transfer zone. At least two air bearings are present, mounted between the rotatable sleeve and the non-rotating sleeve, such that the air bearings are on opposite sides of the first fluid transfer zone.
