A lightweight paper wound Phenolic resin shell avoids the problem of galvanic corrosion and is suitable for metal stern tubes. These bearings do not possess the structural stability of metals and have a shorter operational life. They swell slightly when immersed in water and are therefore machined to tolerances to accommodate this.

High quality marine cutlass bearings, precision manufactured for stern tubes, engine shafts and more.

Manufactured in brass with long lasting polyurethane lining. The lining of the bearing has shaped grooves, or flutes, designed specifically to optimise water lubrication, giving very low friction and helping to maintain hydrodynamic lubrication even at low speeds and high loads. The bearings support the shaft and at the same time assist the flow of water into the bearing, providing lubrication exactly where it is needed.

The profile of the grooves is specially designed so that the rotation of the shaft encourages a dynamic film of water to be driven between the surfaces, producing exceptional anti-vibration and dampening qualities and reducing wear, thus prolonging the working life of the bearing.
