An air bearing assembly includes a split bearing with a first portion and a second portion configured to join and form a female tapered section with distal ends of a larger diameter than a joining central portion. A shaft with a male section including distal ends of a larger diameter than a central portion mates with the female tapered section formed by the joined split bearing. In order to provide adequate lubrication, support, and cooling, one or more an passages in the split bearing fluidly communicates a supply of pressurized air to the shaft. The air pressure provides a cushion of air for the shaft to float on during operation.
