A slipper bearing such as used in a coupling in a drive line of a blooming mill comprises a replaceable bearing forming part of the coupling. The slipper bearing disclosed is of conventional size and shape and is a composite structure having a cast ferrous metal core and softer bronze alloy wearing surfaces. The soft shell construction uses the harder ferrous metal core usually cast steel for its ability to resist breakage and for maintaining the shape and insuring the positioning of the slipper bearing in the coupling of the drive line of the blooming mill while the softer bronze alloy metal forming the wearing surfaces contributes to an unusually long trouble free life.
