BEARING, BUSH - A plain bearing in which the lining is closely fitted into the housing in the form of a bush, usually surfaced with a bearing alloy. 

BEARING, SLEEVE - A cylindrical plain bearing used to provide radial location for a shat, which moves axially. Sleeve bearings consist of one or more layers of bearing alloys, bonded to a steel backing. 

The common rotor shaft of HP turbine and HP compressor was supported on two bearings provided with multiple plain surfaces. The compressor section of the rotor shaft was made of one forged piece using low-alloyed steel. This semi-finished forging was then machined to a...
