What is a Connecting Rod?

A connecting rod is a vital mechanical component found in reciprocating engines, compressors, and pumps. It connects the piston to the crankshaft, transmitting the force from piston movement to create rotational output. This conversion is essential in internal combustion engines, making the connecting rod a cornerstone of engine mechanics.

Designed to withstand high stress, connecting rods must balance strength, weight, and durability. They are commonly made from forged steel, aluminum, or titanium, depending on the application requirements.
