Vetus RL7090PH Phenolic Cutlass Bearing for 70 mm Marine Propeller Shaft
The Vetus RL7090PH cutlass bearing is engineered for propulsion systems requiring precise shaft guidance and long-term water-lubricated performance. Built for a 70 mm shaft and designed to fit a stern tube with a 90 mm outer diameter, it features a lightweight phenolic resin shell combined with a durable polyurethane rubber lining. The grooved inner surface ensures continuous water circulation for effective cooling and lubrication under operating load.
Manufacturer Vetus Model RL7090PH Shaft Diameter 70 mm Outside Diameter 90 mm Length 280 mm Shell Material Phenolic resin Rubber Lining Polyurethane with longitudinal grooves Shell Size (inch) 3 35/64
Key Features
- Phenolic resin outer shell offering lightweight and corrosion-free performance.
- Polyurethane rubber lining with high resistance to wear.
- Grooved internal surface for optimal water lubrication and cooling.
- Designed for metric shaft and stern tube dimensions.
- Suitable for use on motorboats and sailing yachts.
Technical Function
Cutlass bearings support and align the propeller shaft, minimizing friction and vibration while relying on water for lubrication. The grooved rubber lining ensures sufficient water flow to maintain a stable operating temperature and prolong service life in marine environments.
When to Choose Phenolic vs. Brass Bearings
- Phenolic bearings: Recommended for aluminum stern tubes or installations where metal-to-metal contact must be avoided.
- Brass bearings: Common in general marine use due to strength and durability, but not ideal in environments sensitive to galvanic corrosion.
Vetus rubber bearings for larger shaft diameters are also available on special order.
