About this bearing
The MIBSF40 is a genuine Exalto brass cutlass bearing from the Standard Marine Range, manufactured in the United Kingdom to OEM tolerances. Nominal size is 40mm x 2 1/8" x 160mm. It fits a propeller shaft measuring 40.08 – 40.18 mm and seats in a stern tube housing of 2.1262 – 2.1270". Overall length is 160 mm.
Exalto brass-shelled cutlass bearings pair a phenolic liner with a naval brass outer shell. They're chosen when the stern tube bore is slightly loose or worn, giving the mechanical grip of a metal-to-metal interference fit that a bare phenolic or rubber bearing couldn't achieve. Heavier and more expensive, but extremely long-lived.
Every Exalto Standard Marine Range bearing is produced in the UK using the same manufacturing processes trusted by boatyards and refit shops worldwide. We hold Australian stock and ship nationwide for free, so you're ordering from a local warehouse instead of waiting on international freight.
