ABSTRACT:
A piston casting for forming a piston for an internal combustion engine or compressor comprises a generally cylindrical crown (10) having a ring belt (11) extending around the crown for the formation therein of one or more piston ring grooves. A gudgeon pin bore (14) extends through the piston casting in a direction normal to the piston axis and two opposed skirt thrust surfaces (17) depend from the ring belt and are symetrically disposed about a plane including the piston axis and normal to the gudgeon pin bore axis. The surfaces extend only part the way around the piston casting and terminate in respective spaced generally axially extending edges (18), each skirt thrust surface being extended circumferentially beyond the associated edges (at 19) at the ends of the edges remote from the crown.
