Vetus RL13/4PH Phenolic Cutlass Bearing for 1-3/4" Marine Propeller Shaft
The Vetus RL13/4PH cutlass bearing is engineered for marine propulsion systems where corrosion-free, non-metallic construction is required. Designed for a 1-3/4" propeller shaft and compatible with a stern tube featuring a 2-3/8" outside diameter, the bearing features a phenolic resin outer shell and a polyurethane-rubber lining. The lining incorporates longitudinal grooves to ensure continuous water flow, providing effective cooling and lubrication during shaft rotation.
Manufacturer Vetus Model RL13/4PH Shaft Diameter 1-3/4" Outside Diameter 2-3/8" Length 7" Shaft Diameter (mm) 44.45 mm Length (mm) 177.8 mm Shell Material Phenolic resin Rubber Lining Polyurethane with longitudinal grooves Shell Size (inch) 2 3/8
Key Features
- Phenolic resin outer shell that is lightweight and fully corrosion-free.
- Ideal for aluminum stern tubes and non-metallic propulsion system configurations.
- Polyurethane-rubber lining designed for high wear resistance.
- Grooved internal surface ensuring stable water lubrication and cooling.
- Configured entirely in imperial (inch) dimensions for compatible shaft and stern tube interfaces.
- Suitable for both motorboats and sailing yachts.
Technical Function
Cutlass bearings support and align the propeller shaft, reducing friction, vibration, and operational wear. The longitudinal grooves in the polyurethane lining maintain a consistent flow of water across the bearing surface, providing effective lubrication, heat dissipation, and long-term operating stability in marine environments.
When to Choose Phenolic vs. Brass Bearings
- Phenolic bearings: Best suited for aluminum stern tubes or applications requiring elimination of galvanic corrosion.
- Brass bearings: Standard for most marine installations due to mechanical strength and corrosion resistance but not ideal where dissimilar metal contact must be avoided.
Vetus rubber bearings for larger shaft diameters are available on special order.
