Choose your bearing material
All four Exalto Standard Marine Range materials — manufactured in the United Kingdom and stocked here in Australia.
Exalto Phenolic
Fabric-reinforced phenolic resin. Low friction, dimensionally stable, and the go-to choice for commercial and recreational inboard vessels.
Shop Phenolic →Exalto Rubber
Nitrile rubber bonded to a rigid shell with deep longitudinal water grooves. Excellent for sandy and silty operating conditions.
Shop Rubber →Exalto Brass
Naval brass shell with a phenolic liner. Heavy-duty option for high-load commercial applications where the housing is slightly loose.
Shop Brass →Exalto GRP
Glass-reinforced polyester shell for fibreglass stern tubes. A direct-bond replacement for the original GRP fitted to many production boats.
Shop GRP →Not sure which size you need?
Exalto cutlass bearings are sized by three numbers: the inside diameter (I/D, matches your propeller shaft), the outside diameter (O/D, matches your stern tube housing), and the length. Measure the bearing you're replacing or the shaft and housing it fits into — every bearing on our site lists the exact I/D and O/D tolerance range in its native unit system so you can match it to your measurements with confidence.
Our filter bar lets you narrow down by shaft I/D, housing O/D and length live — pick your shaft size and only the matching bearings show.

Who is Exalto?
Exalto is a British marine manufacturer best known for the Standard Marine Range of cutlass bearings — the water-lubricated sleeve bearings fitted to the propeller shafts of inboard boats and ships. Every bearing in our catalogue is manufactured in the United Kingdom to Exalto's OEM tolerances.
What is a cutlass bearing?
A cutlass bearing sits inside the stern tube of an inboard vessel and supports the propeller shaft where it exits the hull. It's water-lubricated — seawater flows through it as the shaft rotates — and absorbs vibration, dramatically reducing wear on both the shaft and the stern tube.
How long do they last?
A well-sized Exalto bearing in clean saltwater will last 5–10 years on a recreational vessel. Silty, sandy or debris-laden water shortens that significantly — check annually. The classic sign of a worn bearing is excess play when the shaft is moved by hand with the boat out of the water.
Phenolic vs rubber vs brass vs GRP?
Phenolic is the modern default: low friction, swells only slightly, lasts a long time. Rubber is the traditional choice and copes best with sandy water. Brass-shelled bearings are used where the housing is oversize and needs mechanical grip. GRP bonds directly into fibreglass stern tubes.
Do your bearings include GST?
Yes. Every price on this site includes 10% Australian GST. The GST component is itemised on your tax invoice for business customers.
What happens if my size is out of stock?
We accept pre-orders on anything in our catalogue. If a bearing isn't on our shelf, the product page shows Dispatch in 3–4 weeks and you can still order — we'll place your unit on our next container from the UK factory and dispatch as soon as it lands, with free Express Post and no extra cost.
