This clamp on split half coupling is machined from solid steel and mates with the gearbox output coupling to connect a 1.25" (1-1/4") diameter imperial boat propeller shaft to the gearbox, usually via a flexible coupling.
The clamp on split type propeller shaft coupling is machined to suit the boat propeller shaft diameter but can accommodate the variations that can occur with normal boat propeller shaft tolerances. It is simple to install and can be adjusted to the required position on the shaft. This clamp on shaft coupling is bored only (no keyway) and is secured to the boat propeller shaft with the clamp bolts supplied.
Typical applications include:
4" nominal gearbox flanges of PRM, Borgwarner Velvet Drive, ZF, Hurth and Technodrive gearboxes.
Recommended torque for the clamp bolts: 54Nm (40 lbsft)
For propeller shaft diameter 1.25" (bored only, no key way)
a - Flange outside diameter = 4.00"
b - Hole pitch circle = 3.25"
c - Number of holes = 4
d - Hole size = 10mm
e - Register diameter = 2.50" male
f - Coupling length = 3.19"
g - Coupling clamp boss diameter = 3.38"
R & D Marine Clamp on shaft coupling number 202-153D.
