The Vetus RULAG70PH Phenolic Cutlass Bearing is designed for a 70 mm propulsion shaft and features a phenolic resin outer shell with a 3 1/2" outside diameter and a total length of 280 mm. Its polyurethane-rubber lining incorporates longitudinal grooves to ensure continuous water lubrication, reduce friction, and stabilize the shaft during operation. The lightweight, non-metallic phenolic casing is ideal for aluminum stern tubes and applications where galvanic corrosion must be avoided, while compatibility with metric shaft diameter and inch-sized stern tube dimensions allows for versatile integration in marine installations.

Vetus RULAG70PH Phenolic Cutlass Bearing for 70 mm Marine Propeller Shafts
The Vetus RULAG70PH is a water-lubricated cutlass bearing engineered for propulsion systems using a 70 mm shaft together with an imperial-dimension stern tube. Its phenolic resin outer casing, sized at 3 1/2", provides a corrosion-free, lightweight and non-metallic alternative to brass, making it particularly suitable for aluminum boats or installations where galvanic corrosion must be prevented. Inside, the polyurethane-rubber lining features longitudinal grooves to enhance lubrication, cooling efficiency and vibration reduction during continuous operation.
Key Features
- High-wear-resistant polyurethane-rubber lining
- Phenolic resin outer casing in 3 1/2" inch dimensions
- Non-metallic, corrosion-free construction ideal for aluminum stern tubes
- Grooved inner surface for improved water flow 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 70 mm Outer Diameter (Shell Size) 3 1/2" Length 280 mm Shell Material Phenolic resin Lining Material Polyurethane-rubber Lubrication Water-lubricated
Application and Use
Cutlass bearings are essential for maintaining proper alignment and support of marine propeller shafts. Their water-lubricated rubber linings reduce friction, absorb vibration and ensure long-term reliability in demanding marine environments.
Phenolic vs. Brass Bearings
- Phenolic bearings: Recommended for aluminum stern tubes or installations where dissimilar metal contact and galvanic corrosion must be prevented. Lightweight, corrosion-free and non-metallic.
- Brass bearings: Standard in many marine applications due to strength and corrosion resistance, though not suitable where non-metallic solutions are required.
