Abstract
A piston carries on its skirt surface a number of separate strips of a plastics material, such as a polyetheretherketone alloy, so that the strips are hydrodynamically lubricated and transmit lateral thrust from the piston to an associated cylinder or liner. The strips are just proud of the skirt surface and may be contained in recesses formed in the skirt surface.
