Abstract
An adjustable bearing assembly for mounting a rotor in a rotary gas machine includes a tapered roller bearing at the high pressure end to bear the combined axial thrust and radial loads induced on the high pressure end by the working fluid therein and an axially floating bearing at the low pressure end to bear radial load. No axial bearing adjustment or bearing preload is applied to the radial load bearing at the low pressure end to maintain proper internal clearance in the bearing at the high pressure end. To obtain simplified assembly and improved bearing life, initial bearing clearance is provided simultaneously during adjustment of rotor end clearance.
