Vetus RULAG15/8 Brass Cutlass Bearing for 1-5/8" Marine Propeller Shaft
The Vetus RULAG15/8 cutlass bearing is engineered for marine propulsion systems that rely on imperial shaft and stern tube measurements. Designed for a 1-5/8" shaft and installation in a stern tube with a 2-1/8" outside diameter, it features a strong brass outer shell paired with a polyurethane-rubber lining. The inner lining is grooved longitudinally to ensure consistent water lubrication and cooling throughout operation.
Manufacturer Vetus Model RULAG15/8 Shaft Diameter 1-5/8" Outside Diameter 2-1/8" Length 6-1/2" Shaft Diameter (mm) 41.275 mm Length (mm) 165.1 mm Shell Material Brass Rubber Lining Polyurethane with longitudinal grooves Shell Size (inch) 2 1/8
Key Features
- Strong brass outer shell providing excellent corrosion resistance.
- Polyurethane-rubber lining designed for high wear resistance.
- Longitudinally grooved inner surface for optimal water flow and lubrication.
- Fully imperial (inch-based) sizing for shaft and stern tube compatibility.
- Suitable for motorboats and sailing yachts.
Technical Function
Cutlass bearings support and align the propeller shaft, reducing friction and vibration while relying on water as the primary lubricant. The grooved rubber lining maintains a consistent water film, enabling effective cooling, smooth rotation, and extended service life in marine environments.
When to Choose Brass vs. Phenolic Bearings
- Brass bearings: Ideal for standard marine installations due to durability, corrosion resistance, and ability to withstand dynamic loads.
- Phenolic bearings: Recommended for aluminum stern tubes or systems where galvanic corrosion risks must be eliminated.
Vetus rubber bearings for larger shaft diameters are available on special order.
