Vetus RL5070PH Phenolic Cutlass Bearing for 50 mm Marine Propeller Shaft
The Vetus RL5070PH is a marine cutlass bearing engineered for a 50 mm shaft and designed for installation in a stern tube with a 70 mm outside diameter. Its phenolic resin shell provides a lightweight, corrosion-free alternative to metallic housings, making it particularly suitable for aluminum boat structures. The internal polyurethane rubber lining incorporates longitudinal grooves that ensure continuous water flow for cooling and lubrication during operation.
Manufacturer Vetus Model RL5070PH Shaft Diameter 50 mm Outside Diameter 70 mm Length 200 mm Shell Material Phenolic resin Rubber Lining Polyurethane with longitudinal grooves Shell Size (inch) 2 3/4
Key Features
- Phenolic resin outer shell for lightweight, corrosion-free installation.
- Polyurethane rubber lining with high wear resistance.
- Longitudinal grooves for optimized water lubrication and cooling.
- Designed for metric shaft and stern tube diameters.
- Suitable for both motorboats and sailing yachts.
Technical Function
Cutlass bearings provide critical support and alignment for the propeller shaft. The grooved rubber lining reduces friction, absorbs vibration, and ensures effective water lubrication for long-term operational reliability in marine environments.
When to Choose Phenolic vs. Brass Bearings
- Phenolic bearings: Recommended for aluminum stern tubes or installations where dissimilar metal contact must be avoided.
- Brass bearings: Commonly used in standard marine applications due to their strength, but not preferred in corrosion-sensitive or mixed-metal environments.
Vetus rubber bearings for larger shaft diameters are also available on special order.
