Cutlass bearings:

with outer casing of bronze or phenolic composite, see descriptions below:

Brass

Brass is supplied as standard and is structurally the strongest material but is not appropriate for steel or aluminium stern tubes. Naval Brass can be supplied on request.

Phenolic

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.

Anodes:

SVariety of shaft ball and ring anodes, manufactured of either zinc or aluminium.
