Vetus RULAG13/4 Brass Cutlass Bearing for 1-3/4" Marine Propeller Shaft
The Vetus RULAG13/4 cutlass bearing is designed for marine propulsion systems that utilize imperial shaft and stern tube specifications. Built for a 1-3/4" shaft and intended for installation in a stern tube with a 2-3/8" outside diameter, this model combines a durable brass shell with a polyurethane-rubber lining. Longitudinal grooves inside the lining ensure continuous water flow, providing essential lubrication and cooling during shaft rotation.
Manufacturer Vetus Model RULAG13/4 Shaft Diameter 1-3/4" Outside Diameter 2-3/8" Length 7" Shaft Diameter (mm) 44.45 mm Length (mm) 177.8 mm Shell Material Brass Rubber Lining Polyurethane with longitudinal grooves Shell Size (inch) 2 3/8
Key Features
- Brass outer shell offering high durability and corrosion resistance.
- Polyurethane-rubber lining engineered for long service life.
- Grooved inner surface for optimal water lubrication and cooling.
- Fully imperial (inch-based) dimensions for shaft and stern tube compatibility.
- Suitable for both motorboats and sailing yachts.
Technical Function
Cutlass bearings support and align the propeller shaft while minimizing vibration and friction. The grooved polyurethane lining enables continuous water flow, ensuring lubrication, cooling efficiency, and stable long-term operation in marine environments.
When to Choose Brass vs. Phenolic Bearings
- Brass bearings: Ideal for standard marine applications requiring strength, load capacity, and corrosion resistance.
- Phenolic bearings: Preferred for aluminum stern tubes or installations where galvanic corrosion must be avoided.
Vetus rubber bearings for larger shaft diameters are available on special order.
