Cutlass bearing size chart
Compare 214 Exalto catalogue bearings by nominal shaft diameter, housing bore and length. Each row links to a product page with its current price and availability.
How to use the dimensions
Record the vessel's specified shaft size, housing bore and bearing length. Keep the original units: 1 inch is 25.4 mm, so a 25 mm shaft needs a different nominal bearing size. A matching length is part of the specification; do not calculate it from shaft diameter alone.
The chart uses each bearing's native units. Mixed metric/imperial bearings have a metric shaft diameter and length with an imperial housing diameter. The display toggle changes inch dimensions between fractional and decimal forms.
Matching dimensions identifies candidates. Check the shell material, housing condition, running clearance, mounting method and application before ordering. A rudder skeg bearing requires a specification for its steering arrangement.
Cutlass bearing sizes by shaft diameter
These shaft sizes each have two or more bearings, compared on their own page by housing bore, length, material, price and availability.

Nominal sizes and manufacturing tolerances
The shaft and housing columns show nominal sizes. Product pages separately list the manufactured bearing bore and outside-diameter tolerances. The bearing bore includes running clearance around its designated shaft. A light interference fit requires the bearing outside diameter to be slightly larger than the specified housing bore before fitting.
Use Exalto's specified fit and clearance rather than adding an allowance yourself. Check a damaged, tapered or oval housing before choosing a replacement. The measuring guide explains what to record.
Choose a compatible shell
Exalto's standard brass, phenolic and GRP sleeve bearings all have a nitrile rubber lining. The names describe their outer shells. Choose a shell that suits the housing and the vessel's bearing specification.
- Phenolic: A phenolic outer shell with a grooved nitrile rubber lining. The non-metallic shell avoids galvanic corrosion between the bearing shell and a metal housing. Exalto allows for phenolic water absorption in its manufacturing tolerances.
- Brass: A brass outer shell with a grooved nitrile rubber lining. Exalto advises against fitting brass directly into steel or aluminium housings. A worn or oversized housing needs assessment; changing shell material does not correct its bore dimensions.
- GRP: A glass-reinforced composite outer shell with a grooved nitrile rubber lining. Exalto identifies GRP as suitable for steel and aluminium stern tubes as well as compatible non-metallic housings. Follow the specified fit and retention method.
- Rubber: An all-rubber bearing without a rigid outer shell. This design uses its own mounting arrangement. Choose it when the vessel specification calls for an all-rubber bearing, and confirm the dimensions and retention method before fitting.
See Exalto's shell and lining specifications for the manufacturer's guidance.
Need help identifying a bearing?
Send the boat model, bearing location, shaft diameter, housing bore, length and any readable part code through our contact page. Include the units for each measurement. If you are changing brands, compare the complete specifications rather than relying on a name or a nominal size alone.
