Abstract

An aerodynamically supported roller bearing is disclosed, having means for connecting a compressed gas supply and using the compressed gas to bring the roller up to a desired speed. The design of the roller then permits the compressed gas supply to be reduced or turned off while the roller continues to be aerodynamically supported. Advantageously, some minimal compressed gas is continued through the roller to purge the roller of potential dust particles interfering with the operation of the roller.
