About this bearing

The IBSF24 is a genuine Exalto brass cutlass bearing from the Standard Marine Range, manufactured in the United Kingdom to OEM tolerances. Nominal size is 3" x 4" x 12". It is designated for a 3" shaft and a nominal 4" housing bore. Confirm the specified housing fit and application before fitting. The tolerance ranges above describe the finished bearing dimensions. Overall length is 12".

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.

Refer to Exalto's shell and lining guidance and installation instructions. A bearing with matching nominal dimensions still needs a compatible material, clearance and mounting arrangement.

This bearing is out of stock and available to pre-order. The dispatch estimate is shown above. Shipping within Australia is free.
