Vetus RL4055PH Phenolic Cutlass Bearing for 40 mm Marine Propeller Shafts
The Vetus RL4055PH is a water-lubricated cutlass bearing designed for propulsion systems using a 40 mm shaft and a metric-dimension stern tube. Its phenolic resin outer casing provides a lightweight, non-metallic and corrosion-free alternative to brass, making it especially suitable for aluminum hulls and installations where avoiding galvanic corrosion is essential. The polyurethane-rubber inner lining features longitudinal grooves that promote continuous water flow, ensuring consistent cooling, lubrication and reduced friction under marine operating loads.
Key Features
- High-wear-resistant polyurethane-rubber lining
- Phenolic resin outer casing for lightweight, corrosion-free construction
- Longitudinal grooves for optimal water lubrication and cooling performance
- 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 critical role in supporting and aligning marine propeller shafts. Their water-lubricated rubber linings minimize friction, absorb vibration and enable reliable long-term operation even in demanding marine environments.
Phenolic vs. Brass Bearings
- Phenolic bearings: Best suited for aluminum stern tubes or environments where dissimilar-metal contact and galvanic corrosion must be avoided. Lightweight and fully corrosion-free.
- Brass bearings: Preferred for most standard marine applications due to strength and resistance to corrosion, but not ideal where non-metallic construction is required.
