Piston Pins

This pin is typically found in a sliding crosshead that is connected to the piston by a rod in most engine configurations, including steam-powered engines, huge stationary engines, and/or engines used in ships.

A high-strength steel alloy is typically used to forge this pin, which is a small hollow rod. In the case of small, high-revving car engines, the pin design is difficult. Let's see how the piston pin functions.
