Vetus RL13/8PH Phenolic Cutlass Bearing for 1-3/8" Marine Propeller Shaft
The Vetus RL13/8PH cutlass bearing is engineered for propulsion systems requiring non-metallic, corrosion-free materials. Designed for a 1-3/8" shaft and installation in a stern tube with a 1-7/8" outside diameter, this bearing combines a phenolic resin outer shell with a polyurethane-rubber lining. Longitudinal grooves in the lining promote continuous water flow, ensuring efficient lubrication and cooling during operation.
Manufacturer Vetus Model RL13/8PH Shaft Diameter 1-3/8" Outside Diameter 1-7/8" Length 5-1/2" Shaft Diameter (mm) 34.93 mm Length (mm) 139.7 mm Shell Material Phenolic resin Rubber Lining Polyurethane with longitudinal grooves Shell Size (inch) 1 7/8
Key Features
- Non-metallic phenolic outer shell that cannot corrode.
- Lightweight construction ideal for aluminum stern tubes.
- Polyurethane-rubber lining with excellent wear resistance.
- Longitudinal grooves ensuring continuous water lubrication and cooling.
- Imperial (inch-based) sizing for full compatibility with corresponding shaft and stern tube dimensions.
- Suitable for motorboats and sailing yachts.
Technical Function
Cutlass bearings support and align the propeller shaft, minimizing friction, vibration, and wear. The grooved polyurethane lining maintains a stable water film, enhancing lubrication, thermal performance, and long-term reliability in marine environments.
When to Choose Phenolic vs. Brass Bearings
- Phenolic bearings: Best choice for aluminum stern tubes or installations requiring non-metallic components to prevent galvanic corrosion.
- Brass bearings: Standard for most marine systems due to strength and corrosion resistance but not ideal for mixed-metal setups.
Vetus rubber bearings for larger shaft diameters are available on special order.
