About this bearing

The MPSF70 is a genuine Exalto phenolic cutlass bearing from the Standard Marine Range, manufactured in the United Kingdom to OEM tolerances. Nominal size is 70 x 90 x 280mm. It fits a propeller shaft measuring 70.33 – 70.43 mm and seats in a stern tube housing of 90.037 – 90.059 mm. Overall length is 280 mm.

Exalto's phenolic cutlass bearings are fabric-reinforced phenolic resin — the modern standard for commercial and recreational inboard vessels. Low coefficient of friction against stainless or bronze propeller shafts, excellent vibration damping, and minimal swell in water. Exalto's published I/D tolerances already account for the slight dimensional change that occurs when the bearing is submerged, so no additional clearance needs to be added.

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.
