Exalto Bearings Ltd.

Standard Cutlass Bearing Range

We can manufacture bearings to suit your size specifications using a variety of shell materials, shell linings and flute designs. Or we can supply you directly from our extensive stock for quick delivery.

Shell Materials

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.

GRP

GRP, fibre-glass composite, is an excellent alternative to Brass for aluminium or steel stern tubes and has very little hydroscopic absorption. It is more stable than Phenolic and is easy to remove from the bracket or shaft.
