This paper elucidates a method of using shop air to seal oil lubricated bearings. A graphical solution of Rayleigh’s equation is presented as a design aid. The efficacy of this sealing method is supported by experimental evidence derived during the development of an ultrahigh-vacuum high-speed rotary feedthrough.
