ABSTRACT:
A bearing assembly comprises a piston mounted within and capable of reciprocating with respect to a fixed bearing shell. The bearing shell is provided with openings for the supply of a bearing medium, such as compressed air, into a clearance between the piston and the bearing shell. The bearing shell is tapered circumferentially which renders the bearing shell flexible. As the diameter of the piston increases due to thermal expansion, the diameter of the bearing shell changes automatically to maintain the clearance therebetween.
