About this bearing

The MGSF30 is a genuine Exalto grp cutlass bearing from the Standard Marine Range, manufactured in the United Kingdom to OEM tolerances. Nominal size is 30 x 45 x 120mm. It fits a propeller shaft measuring 30.08 – 30.18 mm and seats in a stern tube housing of 45.026 – 45.042 mm. Overall length is 120 mm.

Exalto GRP (glass-reinforced polyester) cutlass bearings are designed for direct bonding into fibreglass stern tubes — common on production fibreglass boats where the stern tube is moulded as part of the hull. The GRP shell fuses with the stern tube for a permanent installation.

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.
