202-027 R&D 5" Short Solid Half Coupling Pilot Bored

This solid half coupling is machined from solid steel and mates with the gearbox output coupling to connect a boat propeller shaft to the gearbox, usually via a flexible coupling. This solid shaft half coupling is pilot bored and needs to be machined to suit the boat propeller shaft diameter.

Typical applications include:

5" nominal gearbox flanges of PRM, Borgwarner Velvet Drive, ZF, Hurth, Technodrive and Volvo gearboxes.

Replaces PRM coupling MT771
