Connecting rod is a component of a piston engine that joins the piston to the crankshaft. It is used in conjunction with the crank, transforms the piston's reciprocating motion into the crankshaft's rotation. In addition to this, the said product is ideal for changing the piston's sliding motion into a rotational motion. At the front of the crankshaft are attached the distribution, a crankshaft pulley, and frequently a vibration damper. A plain bearing is used to mount the connecting rod to the crankshaft's crank pin. Most of the time, it is hollow or equipped with an internal cast oil duct to deliver lubricant to the gudgeoned pin.
