Piston Pin, also known as gudgeon pin, is a hollow rod having a small diameter which is typically manufactured using diverse materials especially alloy steel that exhibits high strength and robust properties. The pins produced can withstand high temperatures though they are small, light and can crucially need to withstand heavy loads and bending forces as well. Each piston pin is worn, abrasion and corrosion resistant to provide a long life to the engine. These are prominently used in all types of combustion engines.
