Start with the nominal shaft diameter, housing bore and specified bearing length. Keep the units and confirm the material and mounting arrangement. Bearing tolerances describe the manufactured part; they are separate from the nominal shaft and housing sizes.
The bearing selector starts with shaft and housing sizes. Each match shows its length for you to check.

Who is Exalto?
Exalto manufactures water-lubricated marine bearings for shaft and stern gear applications. Every bearing in our catalogue is manufactured in the United Kingdom to Exalto's OEM tolerances.
What is a cutlass bearing?
A cutlass bearing supports the propeller shaft in a stern tube or external shaft bracket. Water passes through grooves in the lining for lubrication and cooling.
How long do they last?
Bearing life depends on operating conditions, alignment and water supply. Increasing movement, damaged rubber or vibration warrants inspection. Ask the yard to measure clearance and compare it with the manufacturer's guidance; a new bearing has running clearance too.
Phenolic vs rubber vs brass vs GRP?
Phenolic, brass and GRP describe the outer shell; all three have nitrile rubber linings. All-rubber bearings have no rigid outer shell. Choose a design compatible with the housing, fitting specification and application.
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?
Products marked for pre-order have an estimated dispatch window of 3 to 4 weeks. By-request or unpriced items need a quote first. We will contact you if a pre-order estimate changes and offer the option to wait or receive a full refund.
