Piston Pins

Piston Pins or Gudgeon Pins are used in all combustion engines and are arguably one of the most highly stressed components of an engine.  To achieve the specification demanded by the industry, the pins are highly engineered and have come to be a speciality of Coker Engineering.

The piston pin or gudgeon pin is a hollow rod with a small diameter that is typically made of an alloy steel exhibiting high strength and hardness properties.The pins are manufactured to withstand very high temperatures whilst being small and light and crucially need to be able to withstand heavy loads and bending forces.

With many years experience of manufacturing piston pins for the motorsport market and various other industries, Coker Engineering have built up a wealth of experience and skill in this crucial area.
