Connecting Rod
Daihatsu, Yanmar, MAK, Bergen and Other Marine Engine
Refurbished
The Connecting Rod is one of the most important mechanical components in marine diesel engines. It serves as the critical link between the piston assembly and the crankshaft, transmitting combustion forces generated inside the cylinder into rotational motion that drives the ship's propeller.
In large two-stroke marine engines manufactured by MAN B&W, Sulzer, Wärtsilä, Mitsubishi, Hyundai Himsen, Daihatsu, Yanmar, Mak, Bergen, and Pielstick, the connecting rod is engineered to withstand extremely high compression loads, tensile forces, vibration, and continuous operation over thousands of running hours.
A properly maintained connecting rod assembly ensures smooth power transmission, reduced engine wear, improved fuel efficiency, and reliable vessel propulsion. Failure of a connecting rod can result in severe engine damage, making regular inspection and maintenance essential for ship operators and marine engineers.
SM MARINE SERVICE™ supplies connecting rods and associated spare parts for a wide range of marine diesel engines operating onboard commercial vessels worldwide.
A connecting rod converts the reciprocating motion of the piston into rotational motion through the crankshaft system. In low-speed two-stroke marine diesel engines, the connecting rod typically connects the crosshead assembly to the crankshaft via the crankpin bearing.
The connecting rod assembly generally includes:
Modern marine connecting rods are manufactured using forged steel materials and undergo extensive machining and quality control procedures to ensure durability under extreme operating conditions.
SM MARINE SERVICE™ supplies complete connecting rod assemblies, reconditioned units, replacement bearings, bolts, bushes, and overhaul components according to customer requirements.
MAN B&W engines are among the most widely installed propulsion engines in the world.
Popular engine models include:
These engines use heavy-duty connecting rods specifically designed for long service intervals and high-load marine operation.
SM MARINE SERVICE™ can source connecting rods and spare parts for both active and obsolete MAN B&W engine models.
Sulzer and Wärtsilä engines remain common aboard bulk carriers, tankers, and container vessels.
Frequently supported models include:
These engines require precision-engineered connecting rods capable of handling high combustion pressures and long operating cycles.
Marine operators continue to rely on:
SM MARINE SERVICE™ supports sourcing and supply of connecting rods for these engine platforms worldwide.
Marine connecting rods are manufactured from forged alloy steel to withstand extremely high combustion and inertia loads.
Critical surfaces are machined to strict tolerances to ensure proper alignment and bearing performance.
Proper lubrication and maintenance enable connecting rods to operate reliably for extended service periods.
Internal lubrication passages help ensure adequate oil distribution to bearings and moving components.
High-quality connecting rods contribute to smoother engine operation and reduced wear of associated components.
