The Vetus RL11/8PH cutlass bearing is designed for a 1-1/8" propeller shaft and features a phenolic resin outer shell with a 1-5/8" outside diameter and a 4-1/2" length. Its polyurethane-rubber lining is grooved longitudinally to maintain consistent water lubrication and cooling, while the lightweight, corrosion-free phenolic construction makes the bearing ideal for aluminum stern tubes and installations requiring fully non-metallic components.

Vetus RL11/8PH Phenolic Cutlass Bearing for 1-1/8" Marine Propeller Shaft
The Vetus RL11/8PH cutlass bearing is engineered for marine propulsion systems that require corrosion-free, non-metallic bearing construction. Designed for a 1-1/8" shaft and intended for installation in a stern tube with a 1-5/8" outside diameter, it features a phenolic resin outer casing combined with a polyurethane-rubber lining. The lining incorporates longitudinal grooves to maintain a continuous water film for effective lubrication and cooling.
Manufacturer Vetus Model RL11/8PH Shaft Diameter 1-1/8" Outside Diameter 1-5/8" Length 4-1/2" Shaft Diameter (mm) 28.575 mm Length (mm) 114.3 mm Shell Material Phenolic resin Rubber Lining Polyurethane with longitudinal grooves Shell Size (inch) 1 5/8
Key Features
- Non-metallic phenolic outer shell that cannot corrode.
- Lightweight construction ideal for aluminum stern tubes.
- Polyurethane-rubber lining with high wear resistance.
- Longitudinal grooves ensuring stable water lubrication and cooling.
- Fully imperial sizing for shaft and stern tube compatibility.
- Suitable for motorboats and sailing yachts.
Technical Function
Cutlass bearings provide essential support and alignment for the propeller shaft, minimizing friction, vibration, and wear. The grooved polyurethane lining maintains a consistent flow of water across the bearing surface, improving lubrication, cooling performance, and long-term service reliability in marine environments.
When to Choose Phenolic vs. Brass Bearings
- Phenolic bearings: Recommended for aluminum stern tubes or installations requiring elimination of galvanic corrosion risks.
- Brass bearings: Standard for most marine applications due to their high strength and corrosion resistance, but not ideal for mixed-metal environments.
Vetus rubber bearings for larger shaft diameters are available on special order.
