Piston Pins

Piston pins are mainly used in the diesel engine industry and are cylindrical pins mounted on the piston skirt. Its middle part passes through the small head hole of the connecting rod and is used to connect the piston and the connecting rod. Its function is to transmit the gas force borne by the piston to the connecting rod or to make the small head of the connecting rod drive the piston to move together. To reduce weight, the piston pin is generally made of high-quality alloy steel and made hollow.

The piston pin bears a large periodic impact load under high-temperature conditions, and the design requires high enough mechanical strength, wear resistance, and fatigue resistance.
