Contacting bushing seals feature very low gas consumption for both dynamic and static operation modes. In static operation the carbon segments will contact the shaft reducing gas consumption to a minimum. In dynamic operation, the profiled inner surface of the segmented ring will ensure an aerodynamic lift-off at circumferential speeds >10 m/s (33 ft/s). The segmented carbon rings float on a very thin gas film of few µm.
