Abstract
An asymmetric split bearing with a geometrically contoured work surface is provided that has an upper segment and lower segment and a plurality of spaced, recesses in the sidewall of the bearing segment, which are joined together by means of bearing surfaces or lands. The asymmetric split bearing allows for a greater range of applications, such as reciprocating engine crankshafts, which require split bearings for support. The number of bearing surfaces on each segment can be optimized for load conditions and to minimize friction. The bearing utilizes powdered metal manufacturing and is self-cleaning.
