Abstract
A scroll compressor has an orbiting scroll which has an end plate with a hub extending generally perpendicular from the end plate. The hub defines a bore within which a bearing is press fit. The machining of the bore in the hub is done in a conical manner to accommodate and compensate for the unequal distortion of the hub between the two ends of the hub. The conical shape and the unequal distortion provide an assembled bearing with a more cylindrically shaped inner surface.
