<p>A standard (102) and method for supporting a bearing (142) for a rotating shaft (108) of a machine (100) including a plurality of casings having different gas pressures greater than atmospheric pressure includes a sealed chamber (140) for fluidly coupling to an end packing of a first casing (104) and a second casing (124) of the machine (100), the sealed chamber (140) having a pressure greater than atmospheric pressure. The pressure in the sealed chamber (140) reduces the leakage from the casing making more pressurized gas available for producing work in the machine (100).
