New product
The Crosshead Bearing is one of the most critical components used in low-speed two-stroke marine diesel engines installed onboard commercial vessels worldwide. It forms the vital connection between the connecting rod and the crosshead pin, allowing the transfer of enormous combustion forces from the piston assembly to the crankshaft while maintaining smooth engine operation.
Crosshead bearings are designed to withstand extremely high dynamic loads, continuous vibration, fluctuating temperatures, and harsh marine operating conditions. Modern marine engines manufactured by MAN B&W, Sulzer, Wärtsilä, Mitsubishi, Hyundai Himsen, Daihatsu, Yanmar, Mak, Bergen, and Pielstick rely heavily on high-quality crosshead bearing assemblies for safe and efficient propulsion.
For shipowners, fleet managers, superintendents, and marine engineers, maintaining healthy crosshead bearings is essential for preventing costly engine damage, reducing downtime, improving fuel efficiency, and extending engine service life.
SM MARINE SERVICE™ supplies crosshead bearings and related spare parts for a wide range of marine diesel engines operating worldwide.
A crosshead bearing is installed between the connecting rod and the crosshead pin in low-speed marine diesel engines. Unlike trunk piston engines, low-speed crosshead engines separate piston side thrust from the crankshaft mechanism, significantly reducing wear and improving engine reliability.
The bearing normally consists of:
Crosshead bearings operate under hydrodynamic lubrication conditions where a thin oil film separates the bearing surface from the rotating pin. Proper lubrication is critical because bearing failure can lead to catastrophic engine damage.
Marine engineers routinely inspect crosshead bearings during major overhauls to monitor wear patterns, white metal condition, oil film quality, and bearing clearance.
SM MARINE SERVICE™ supports both new and reconditioned crosshead bearing assemblies depending on vessel requirements and maintenance budgets.
MAN B&W MC, MC-C, ME, ME-C, and ME-B engines are among the most common propulsion engines found on container vessels, bulk carriers, crude oil tankers, chemical tankers, LNG carriers, and LPG carriers.
Popular engine models include:
Crosshead bearings for these engines are engineered for long service intervals and high reliability.
Sulzer and Wärtsilä engines continue to operate on thousands of vessels worldwide.
Common engine families include:
These engines require precision-manufactured crosshead bearings capable of handling high combustion pressures and extended operating cycles.
Crosshead bearings are also widely used in:
SM MARINE SERVICE™ can source and supply bearings for both current and obsolete engine models.
Crosshead bearings are specifically designed to withstand the enormous combustion forces generated in large marine diesel engines.
Most marine crosshead bearings utilize white metal lining technology that provides excellent anti-friction performance and protection against seizure.
Internal oil passages ensure continuous lubrication and cooling during engine operation.
When properly maintained, marine crosshead bearings can provide reliable operation for thousands of running hours.
Proper bearing condition helps protect crosshead pins, connecting rods, crankshafts, pistons, cylinder liners, and other major engine components.
