The Vetus RULAG50PH Phenolic Cutlass Bearing is designed for a 50 mm propulsion shaft and features a phenolic resin outer shell with a 2 5/8" outside diameter and a total length of 200 mm. Its polyurethane-rubber lining includes longitudinal grooves that maintain continuous water lubrication, reduce friction, and ensure stable shaft performance. The lightweight, corrosion-free phenolic casing makes this model especially suitable for aluminum stern tubes and installations where galvanic corrosion must be avoided, while compatibility with metric shafts and inch-sized stern tubes enables broad marine application.

Vetus RULAG50PH Phenolic Cutlass Bearing for 50 mm Marine Propeller Shafts
The Vetus RULAG50PH is a water-lubricated cutlass bearing designed for marine propulsion systems using a 50 mm shaft in combination with an imperial-dimension stern tube. Its phenolic resin outer casing, sized at 2 5/8", provides a lightweight, corrosion-free and non-metallic alternative to brass, making it ideal for aluminum boats or installations where galvanic corrosion risks must be avoided. The polyurethane-rubber lining incorporates longitudinal grooves to ensure efficient cooling, lubrication, and vibration reduction.
Key Features
- High-wear-resistant polyurethane-rubber lining
- Phenolic resin outer casing in 2 5/8" inch dimensions
- Lightweight, corrosion-free construction ideal for aluminum stern tubes
- Longitudinal grooves for continuous water lubrication and cooling
- Designed for metric shaft diameter and imperial stern tube diameter
- Suitable for motorboats and sailing yachts
- Available for larger shaft diameters upon request
Technical Specifications
Parameter Value Shaft Diameter 50 mm Outer Diameter (Shell Size) 2 5/8" Length 200 mm Shell Material Phenolic resin Lining Material Polyurethane-rubber Lubrication Water-lubricated
Application and Use
Cutlass bearings provide critical support and alignment for marine propeller shafts. Their water-lubricated rubber linings reduce friction, absorb vibration, and ensure long-term operational reliability in demanding marine environments.
Phenolic vs. Brass Bearings
- Phenolic bearings: Recommended for aluminum stern tubes or areas where dissimilar-metal contact and galvanic corrosion must be prevented. Lightweight, non-metallic, corrosion-free.
- Brass bearings: Standard for many marine installations due to strength and corrosion resistance, but not ideal where non-metallic construction is required.
