Rudder bearings, sterntube systems and bearings for deck equipment
In line with stricter environmental requirements for shipping, water-lubricated sterntube bearings are an attractive alternative to traditional oil-lubricated bearings.
An oil-lubricated sterntube system contains lubricating oil in direct proximity to the marine environment, which poses a potential risk of oil spillage in the event of a shaft seal failure.
By using water as a lubricant, we eliminate the risk of oil pollution, providing an environmentally friendly solution that complies with the strictest regulations, such as IMO and MARPOL
We are excited to represent one of the world’s leading manufacturers in this segment.
Maprom Engineering specializes in the design and supply of advanced water-lubricated shaft seals, bearings, lubrication systems and complete shaft systems for naval and marine applications and supports navies, shipyards, and system integrators with robust propulsion line solutions engineered for reliability, low maintenance, and environmental compliance.
Their water-lubricated technologies eliminate the need for oil lubrication and reduce environmental risk while ensuring quiet, efficient operation—critical for naval vessels and sensitive maritime platforms. Their (and our) portfolio includes custom-engineered stern tube seals, propeller shaft bearings, integrated shafting systems and lubrication systems, designed to withstand harsh operating conditions and demanding duty cycles.
All solutions are developed in close cooperation with clients to meet applicable naval standards, classification society requirements and customer-specific specifications and are followed throughout the project lifecycle, from new-build programs to retrofits and life-extension upgrades, ensuring precise integration and long-term performance.
