Vetus RL4055 Brass Cutlass Bearing for 40 mm Marine Propeller Shafts
The Vetus RL4055 is a water-lubricated cutlass bearing engineered for propulsion systems using a 40 mm shaft together with a stern tube manufactured in metric dimensions. Its brass outer casing, sized at 55 mm in outer diameter, provides high structural strength and excellent corrosion resistance. The polyurethane-rubber lining features longitudinal grooves to maintain consistent cooling and lubrication while reducing vibration and friction under continuous marine operation.
Key Features
- High-wear-resistant polyurethane-rubber lining
- Brass outer casing for strength and long-term corrosion resistance
- Grooved inner surface for optimal water lubrication and cooling
- Designed for metric shaft and stern tube dimensions
- Suitable for both motorboats and sailing yachts
- Available for larger shaft diameters upon request

Application and Use
Cutlass bearings play a vital role in supporting and aligning marine propeller shafts. Their water-lubricated rubber linings minimize friction, absorb vibration, and deliver long-lasting performance even in demanding marine environments.
Brass vs. Phenolic Bearings
- Brass bearings: Ideal for most marine applications due to their durability, corrosion resistance, and ability to withstand dynamic loads.
- Phenolic bearings: Suitable for aluminum stern tubes or installations where galvanic corrosion must be avoided.
