R&D Marine 6" Long Solid Half Coupling Pilot Bored 808602

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: 6" nominal gearbox flanges of Newage PRM, Borgwarner Velvet Drive and ZF - Hurth gearboxes. Coupling dimensions: a - Flange outside diameter = 5.75" b - Hole pitch circle = 4.75" c - Number of holes = 6 d - Hole size = 0.50" e - Register diameter = 3.00" male f - Coupling length = 5.87" g - Coupling boss diameter = 3.65" h - Pilot bore diameter: 21mm (for customer machining to parallel or taper as required.)
