Vetus RL3PH Phenolic Cutlass Bearing for 3'' Shaft, 4'' OD, 12'' Length
The Vetus RL3PH is a water-lubricated cutlass bearing built with a polyurethane rubber lining and a corrosion-free phenolic resin outer shell. All dimensions of this model—shaft, outer diameter, and length—are specified in inches, ensuring compatibility with stern tubes and shafts designed according to imperial standards. The internal rubber surface is grooved longitudinally to provide continuous water flow, cooling, and lubrication during operation. This bearing is particularly suited for aluminum boats or installations where galvanic corrosion must be avoided.
Key Features
- Polyurethane rubber lining with high wear resistance
- Phenolic resin outer casing, lightweight and corrosion-free
- Longitudinal internal grooves for optimal water lubrication
- Fully imperial dimensions: 3'' shaft, 4'' shell OD, 12'' length
- Suitable for motorboats and sailing yachts
- Ideal for aluminum stern tubes and corrosion-sensitive applications
Technical Specifications
Manufacturer Vetus Shaft Diameter 3" (76.20 mm) Shell Outside Diameter 4" Length 12" (304.8 mm) Outer Shell Material Phenolic resin Lining Material Polyurethane rubber Lubrication Water-lubricated
Application Details
- Designed for precise alignment and support of marine propeller shafts
- Reduces friction and vibration during shaft rotation
- Optimized for installations requiring non-metallic outer shells
- Recommended when avoiding metal-to-metal contact in aluminum stern tubes
Phenolic vs. Brass Bearing Use
Phenolic bearings are preferred for aluminum stern tubes or systems where avoiding galvanic corrosion is essential. Brass bearings remain standard for many marine systems due to their strength and durability, but phenolic variants offer clear advantages in corrosion-sensitive or fully non-metallic installations.
Vetus rubber bearings for larger shaft diameters are available on special request.
