A piston pin (gudgeon pin), which is also known as a wrist pin, is an important component of an internal combustion engine. It establishes a link between the connecting rod and the piston. Gudgeon pins are also useful with connecting rods, wheels, and cranks.
This pin is located in a sliding crosshead that is usually connected to the piston via a rod in most engine arrangements, including steam-powered engines, large stationary and marine engines.
It can be fitted to the skirt of the piston and free to float and rotate, to limit axial movement. A gudgeon-pin must be positioned relative to the piston so that it does not rub against or damage the cylinder.
