Geometrical design of a two-stroke marine diesel engine crosshead bearing with natural fibre composite material

Current two-stroke marine diesel engine crosshead bearings are steel backed with tin based white metal overlayed, similar to conventional journal bearings. With increased environmental pressure, the shift to more sustainable material industries globally including the maritime gained much attention a...
