Vetus RL8010PH Phenolic Cutlass Bearing for 80 mm Marine Propeller Shaft
The Vetus RL8010PH cutlass bearing is designed for marine propulsion systems requiring accurate shaft alignment and reliable water-lubricated performance. Built for an 80 mm shaft and intended for installation in a stern tube with a 100 mm outside diameter, the bearing combines a lightweight phenolic resin shell with a durable polyurethane rubber lining. Longitudinal grooves inside the lining ensure a continuous water film for effective cooling, lubrication, and noise reduction.
Manufacturer Vetus Model RL8010PH Shaft Diameter 80 mm Outside Diameter 100 mm Length 320 mm Shell Material Phenolic resin Rubber Lining Polyurethane with longitudinal grooves
Key Features
- Lightweight phenolic resin outer shell that cannot corrode.
- Polyurethane rubber lining engineered for high wear resistance.
- Grooved internal surface for consistent water lubrication and cooling.
- Designed for metric shaft and stern tube diameters.
- Suitable for motorboats and sailing yachts.
Technical Function
Cutlass bearings support and guide the propeller shaft while minimizing friction and vibration. The water-lubricated rubber lining maintains stable operating temperatures and ensures long-term 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: Common for general marine applications due to strength and durability, though not ideal for corrosion-sensitive setups.
Vetus rubber bearings for larger shaft diameters are available on special order.
