Connecting rods are essential components within the engine's crankcase, forming a critical link between the pistons and the crankshaft. These high-strength parts transmit the reciprocating motion of the pistons into the rotary motion driving the vehicle's drivetrain. Found in both passenger cars and commercial vehicles, connecting rods must withstand significant stresses and fatigue from combustion forces. Key characteristics include precise dimensions, material composition (typically forged steel or aluminum alloy), and bearing surface quality for smooth operation and longevity. Examples in this category include Scania connecting rods (MPN 1789713), MAN diesel engine rods (MPN 51.02400-6226), and MAHLE piston connecting rods (MPN 209PS20152000). Mercedes-Benz truck engine components are also available within this selection.
