ABSTRACT:
An air bearing is coaxially mounted around a rotatable shaft, such as an engine crankshaft, by means of a flexible ring of open cell foam. Air flows through the foam cell ring to the bearing face. In this manner, continuous streams of air will flow past the seal to prevent oil or contaminants from moving in a direction opposite to the air flow direction.
