Key Features
- Durable brass outer shell with excellent corrosion resistance.
- Polyurethane-rubber lining offering high wear resistance.
- Grooved internal surface providing effective water lubrication and cooling.
- Fully imperial sizing for shaft and stern tube compatibility.
- Suitable for motorboats and sailing yachts.
Technical Function
Cutlass bearings provide structural support and alignment for the propeller shaft, reducing friction and vibration. The grooved polyurethane lining maintains a continuous flow of water, ensuring optimal lubrication and operational stability in marine environments.
When to Choose Brass vs. Phenolic Bearings
- Brass bearings: Ideal for general marine installations due to strength, durability, and resistance to corrosion and dynamic loads.
- Phenolic bearings: Preferred for aluminum stern tubes or applications requiring avoidance of dissimilar metal contact.
Vetus rubber bearings for larger shaft diameters are available on special order.
