Requirements of a Piston Pin

1. The pin must have sufficient strength and flexibility to withstand the load without damage. 2. It requires high surface hardness to achieve favorable wear behavior.
3. These pins must achieve high surface quality and size accuracy for optimum fit with their sliding parts, piston, and connecting rod.
4. To keep the inertia forces to a minimum, these pins must have a low weight.
5. The rigidity of the pin should match the design of the piston, so as to avoid overloading the piston.
6. Despite from above, the pin construction should be as simple and thus economical as possible.
