Vetus RULAG11/8 Brass Cutlass Bearing for 1-1/8" Marine Propeller Shaft
The Vetus RULAG11/8 cutlass bearing is engineered for propulsion systems using imperial shaft and stern tube dimensions. Designed for a 1-1/8" shaft and intended for installation in a stern tube with a 1-5/8" outside diameter, it features a corrosion-resistant brass shell and a polyurethane-rubber lining. Longitudinal grooves within the inner lining ensure continuous water flow for effective cooling and lubrication.
Manufacturer Vetus Model RULAG11/8 Shaft Diameter 1-1/8" Outside Diameter 1-5/8" Length 4-1/2" Shaft Diameter (mm) 28.575 mm Length (mm) 114.3 mm Shell Material Brass Rubber Lining Polyurethane with longitudinal grooves Shell Size (inch) 1 5/8
Key Features
- Brass outer shell providing strength and corrosion resistance.
- Polyurethane-rubber lining with high wear resistance.
- Grooved inner surface for stable water lubrication and cooling.
- Fully imperial (inch-based) sizing for shaft and stern tube dimensions.
- Suitable for motorboats and sailing yachts.
Technical Function
Cutlass bearings support and align the propeller shaft, reducing vibration and friction while relying on water as the primary lubricant. The grooved polyurethane lining ensures continuous water flow, maintaining cooling efficiency and long-term operational reliability.
When to Choose Brass vs. Phenolic Bearings
- Brass bearings: Best suited for standard marine applications requiring strength, load capacity, and corrosion resistance.
- Phenolic bearings: Preferred in aluminum stern tubes or environments where galvanic corrosion must be prevented.
Vetus rubber bearings for larger shaft diameters are available on special order.
