Vetus RULAG23/4 Brass Cutlass Bearing for 2-3/4" Marine Propeller Shaft
The Vetus RULAG23/4 cutlass bearing is engineered for marine propulsion systems using imperial (inch-based) shaft and stern tube specifications. Designed for a 2-3/4" shaft and compatible with a stern tube featuring a 3-3/4" outside diameter, this model combines a strong brass shell with a durable polyurethane-rubber lining. The inner lining is machined with longitudinal grooves to maintain effective water lubrication and cooling during continuous operation.
Manufacturer Vetus Model RULAG23/4 Shaft Diameter 2-3/4" Outside Diameter 3-3/4" Length 11" Shaft Diameter (mm) 69.85 mm Length (mm) 279.4 mm Shell Material Brass Rubber Lining Polyurethane with longitudinal grooves Shell Size (inch) 3 3/4
Key Features
- Robust brass outer shell providing strength and corrosion resistance.
- Polyurethane-rubber lining engineered for high wear resistance.
- Grooved inner surface enabling stable water lubrication and cooling.
- Fully imperial (inch-based) shaft and stern tube compatibility.
- Suitable for sailing yachts and motorboats.
Technical Function
Cutlass bearings support and align the propeller shaft, reducing friction, vibration, and mechanical wear. The polyurethane lining, shaped with longitudinal grooves, maintains a continuous water film that ensures smooth rotation, proper cooling, and long service life in marine operating environments.
When to Choose Brass vs. Phenolic Bearings
- Brass bearings: Best suited for standard marine applications requiring durability, corrosion resistance, and strong load-handling characteristics.
- Phenolic bearings: Recommended for aluminum stern tubes or environments where galvanic corrosion must be prevented.
Vetus rubber bearings for larger shaft diameters are available on special order.
