Abstract
In a preferred embodiment, a crosshead piston assembly for four-stroke cycle engines includes a novel piston pin bearing assembly having opposed less than semicylindrical insert bearings retained by engagement of arcuately opposite coplanar edge surfaces with like mating surfaces of respective recesses to provide an assembly capable of being practically manufactured to close dimensional tolerances. Broad potential application of the bearing concept is suggested.
