Vetus RULAG11/4 Brass Cutlass Bearing for 1-1/4" Marine Propeller Shaft
The Vetus RULAG11/4 cutlass bearing is engineered for propulsion systems that use imperial dimensional standards. Designed for a 1-1/4" shaft and compatible with a stern tube having a 1-3/4" outside diameter, the bearing features a durable brass shell and a polyurethane-rubber lining. Longitudinal grooves inside the lining ensure consistent water flow for lubrication and cooling, providing stable performance in marine environments.
Manufacturer Vetus Model RULAG11/4 Shaft Diameter 1-1/4" Outside Diameter 1-3/4" Length 5" Shaft Diameter (mm) 31.75 mm Length (mm) 127 mm Shell Material Brass Rubber Lining Polyurethane with longitudinal grooves Shell Size (inch) 1 3/4
Key Features
- Brass outer shell for strength and corrosion resistance.
- Polyurethane-rubber lining with high wear resistance.
- Grooved internal surface ensuring stable water lubrication and cooling.
- Fully imperial sizing for shaft and stern tube compatibility.
- Suitable for motorboats and sailing yachts.
Technical Function
Cutlass bearings are essential for supporting and aligning the propeller shaft. The grooved rubber lining minimizes friction, absorbs vibration, and maintains continuous water lubrication, ensuring reliable, long-term operation in marine conditions.
When to Choose Brass vs. Phenolic Bearings
- Brass bearings: Ideal for general marine use due to their durability and resistance to corrosion and mechanical stress.
- Phenolic bearings: Preferred in aluminum stern tubes or where galvanic corrosion must be prevented.
Vetus rubber bearings for larger shaft diameters are available on special order.
