The Vetus RULAG80PH Phenolic Cutlass Bearing is built for an 80 mm propulsion shaft and features a phenolic resin outer shell with a 4" outside diameter and a total length of 320 mm. Its polyurethane-rubber lining incorporates longitudinal grooves to ensure continuous water lubrication, minimize friction, and provide stable shaft support. The lightweight, corrosion-free phenolic casing is ideal for aluminum stern tubes and installations where galvanic corrosion must be avoided, while compatibility with a metric shaft and an inch-dimension stern tube enables reliable integration in diverse marine applications.

Vetus RULAG80PH Phenolic Cutlass Bearing for 80 mm Marine Propeller Shafts
The Vetus RULAG80PH is a water-lubricated cutlass bearing engineered for propulsion systems using an 80 mm shaft together with an imperial-dimension stern tube. Its phenolic resin outer casing, sized at 4", provides a lightweight, corrosion-free and non-metallic alternative to brass, making it especially suitable for aluminum boats or installations requiring full protection from galvanic corrosion. The polyurethane-rubber lining features longitudinal grooves to improve water flow, cooling and lubrication under continuous operation.
Key Features
- High-wear-resistant polyurethane-rubber lining
- Phenolic resin outer casing in 4" inch dimensions
- Non-metallic, corrosion-free construction ideal for aluminum stern tubes
- Grooved inner surface for optimal water lubrication and cooling
- Designed for metric shaft diameter and imperial stern tube diameter
- Suitable for both motorboats and sailing yachts
- Available for larger shaft diameters upon request
Technical Specifications
Parameter Value Shaft Diameter 80 mm Outer Diameter (Shell Size) 4" Length 320 mm Shell Material Phenolic resin Lining Material Polyurethane-rubber Lubrication Water-lubricated
Application and Use
Cutlass bearings provide essential support and alignment for marine propeller shafts. Their water-lubricated rubber linings reduce friction, absorb vibration and ensure reliable long-term performance even in demanding operating environments.
Phenolic vs. Brass Bearings
- Phenolic bearings: Recommended for aluminum stern tubes or installations where dissimilar-metal contact and galvanic corrosion must be avoided. Lightweight, corrosion-free and fully non-metallic.
- Brass bearings: Widely used in standard marine applications due to strength and corrosion resistance, though not preferred where non-metallic construction is necessary.
