The Vetus RULAG40PH Phenolic Cutlass Bearing is designed for a 40 mm propulsion shaft and features a phenolic resin outer shell with a 2 1/8" outside diameter and a total length of 160 mm. Its polyurethane-rubber lining incorporates longitudinal grooves to maintain continuous water lubrication, reduce friction, and stabilize the shaft during operation. 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 inch-sized stern tube ensures versatile marine application.

Vetus RULAG40PH Phenolic Cutlass Bearing for 40 mm Marine Propeller Shafts
The Vetus RULAG40PH is a water-lubricated cutlass bearing designed for propulsion systems using a 40 mm shaft in combination with an imperial-dimension stern tube. Its phenolic resin outer casing, sized at 2 1/8", offers a lightweight, corrosion-free and non-metallic alternative to brass, making it particularly suitable for aluminum boats or environments where galvanic corrosion must be avoided. The polyurethane-rubber lining features longitudinal grooves to ensure efficient water lubrication, cooling, and vibration damping.
Key Features
- Polyurethane-rubber lining with high wear resistance
- Phenolic resin outer casing in 2 1/8" inch dimensions
- Non-metallic, corrosion-free construction ideal for aluminum stern tubes
- Grooved inner surface for continuous water flow and improved 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 40 mm Outer Diameter (Shell Size) 2 1/8" Length 160 mm Shell Material Phenolic resin Lining Material Polyurethane-rubber Lubrication Water-lubricated
Application and Use
Cutlass bearings are critical for supporting and aligning the propeller shaft. Their water-lubricated rubber lining minimizes friction, absorbs vibration, and ensures consistent performance even under demanding marine operating conditions.
Phenolic vs. Brass Bearings
- Phenolic bearings: Recommended for aluminum stern tubes or where dissimilar metal contact and galvanic corrosion must be avoided. Lightweight, non-metallic, and fully corrosion-free.
- Brass bearings: Common in standard marine installations due to their strength and corrosion resistance, though not suitable where non-metallic construction is required.
