A bobbin coupling is a double flange coupling, which is used to extend the boat propeller shaft. They can also be used for making a double flexible coupling with two R&D type flexible couplings. This can provide excellent noise and vibration control, at a very reasonable price.
The 6" R&D bobbin coupling is machine from steel, and the flanges will suit gearbox flanges (5.75") for PRM, Borgwarner Velvet Drive, ZF and Twin Disc gearbox.
Bobbin 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 on one flange and female on the other
f - Bobbin coupling length = 5.86"
g - Bobbin neck diameter = 4.25"
