OK Propeller Shaft Greases: Reliable lubrication for the marine industry
The maritime world is all about reliability. Lubrication problems can lead to downtime, damage and high costs. That is why OK offers a complete range of high-quality stern tube greases, specially developed for use in tough conditions on and around the water.
Calcium as the basis for maximum performance at sea
Many of our marine greases are based on anhydrous calcium soap. These greases are ideally suited for wet, salty and contaminated environments – exactly the conditions in which stern tubes operate. Compared to lithium greases, calcium technology offers:
-
Improved adhesion to metal surfaces
-
Excellent water and rinse resistance
-
Superior corrosion protection even under saltwater conditions
-
More sustainable and safe in transportation and storage
The right grease for every application
OK supplies stern tube greases in various compositions and consistencies (NLGI 0 to 3), so you will always have a grease that suits your application:
-
OK Propeller shaft grease EP 2 / EP 3 – Multi-purpose grease for standard applications, with strong adhesion and corrosion protection.
-
OK Propeller stern tube grease EP 2/3 Premium – Workhorse on board with increased base oil viscosity and calcium lithium thickener for additional sealing.
-
OK Propeller Shaft Grease Bio – Biodegradable and powerful grease – environmentally friendly without compromising on performance.
-
OK MP 220 AC 0 – Semi-liquid calcium grease for central lubrication systems, easily pumpable at low temperatures.
More than just stern tubes
Our marine greases are versatile – not only for stern tubes, but also for winches, cables, hinges, bearings, couplings and deck applications. With high-pressure resistance (EP/AW additives), water resistance and oxidation stability, they are built for maximum use on board.
