The Vetus RULAG1 cutlass bearing is built for a 1" propeller shaft and features a brass outer shell with a 1½" outside diameter and a 4" overall length. Its polyurethane-rubber lining is formed with longitudinal grooves to maintain stable water lubrication and cooling, while the robust brass casing provides strength and corrosion resistance for standard marine installations that use imperial (inch-based) dimensions.

Vetus RULAG1 Brass Cutlass Bearing for 1" Marine Propeller Shaft
The Vetus RULAG1 cutlass bearing is designed for propulsion systems using imperial shaft and stern tube measurements. Intended for a 1" shaft and a 1½" outside diameter stern tube, it features a strong brass shell combined with a polyurethane rubber lining. The internal grooves ensure continuous water circulation for lubrication and cooling, providing stable performance in marine environments.
Manufacturer Vetus Model RULAG1 Shaft Diameter 1" Outside Diameter 1½" Length 4" Shell Material Brass Rubber Lining Polyurethane with longitudinal grooves Shell Size (inch) 1 1/2 Shaft Diameter (mm) 25.4 mm Length (mm) 101.6 mm
Key Features
- Brass outer shell engineered for strength and corrosion resistance.
- Polyurethane rubber lining with high wear resistance.
- Grooved inner surface for consistent water lubrication and cooling.
- Designed entirely with imperial (inch) shaft and stern tube dimensions.
- Suitable for both 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 ensures efficient cooling and lubrication, contributing to long-term reliability in demanding marine conditions.
When to Choose Brass vs. Phenolic Bearings
- Brass bearings: The preferred choice for standard marine installations due to durability, load capacity, and corrosion resistance.
- Phenolic bearings: Used mainly in aluminum stern tubes or where dissimilar metal contact must be avoided to prevent galvanic corrosion.
Vetus rubber bearings for larger shaft diameters are also available on special order.
