Piston Rod
Daihatsu, Yanmar, MAK, Bergen and Other Marine Engine
Refurbished
The Piston Rod is one of the most important components in large marine diesel engines, particularly crosshead-type low-speed propulsion engines. It serves as the critical connection between the piston assembly and the crosshead mechanism, transmitting combustion forces from the piston to the crankshaft system.
Marine piston rods operate under extremely demanding conditions involving high combustion pressure, elevated temperatures, continuous cyclic loading, and constant exposure to lubrication systems. Therefore, piston rods are manufactured using high-strength forged steel and precision-machined surfaces to ensure long-term reliability.
A properly maintained piston rod contributes significantly to engine performance, fuel efficiency, operational safety, and overall engine lifespan.
SM MARINE SERVICE™ supplies new, used, and reconditioned piston rods together with repair, reconditioning, inspection, chrome plating, and worldwide technical support services.
MAN B&W low-speed engines utilize heavy-duty piston rods designed to withstand continuous operation in large commercial vessels.
Common applications include:
These piston rods are manufactured with precision tolerances to ensure smooth crosshead movement and reliable power transmission.
WinGD and Sulzer engines use high-strength piston rods specifically designed for large two-stroke propulsion engines.
Benefits include:
Proper inspection and maintenance are essential to prevent wear and corrosion.
Wärtsilä marine engines utilize advanced piston rod designs that provide dependable operation under demanding marine conditions.
Applications include:
Medium-speed and auxiliary marine engines use precision-machined piston rods designed to provide reliable force transmission between pistons and crank mechanisms.
These piston rods contribute to:
Bergen, MAK, Mitsubishi, Akasaka, Hanshin and Niigata engines also utilize robust piston rod assemblies engineered for continuous marine service.
These components are critical for:
A marine piston rod connects the piston assembly to the crosshead or connecting rod mechanism.
