Federal Flexible Couplings a Quality Product since 1953
A Federal Flexible Coupling -- is a true flexible shaft coupling, that helps to absorb vibration
and can help protect marine transmissions against damaging shaft whip, vibration, thrust loads,
and some minor structural distortions and stress at transmission due to flex on motor mounts.
A Federal Flexible Coupling is made to replace a solid (rigid) propeller shaft flange, and bolt
directly to the marine transmission and accept straight cut prop shafts (double taper not avail).
Federal Flexible Couplings consist of a separate hub and flange put together as an assembly.
Parts are accurately machined to match different transmissions. Special rubber bushings are
inserted into the flange, spider pins slide through bushings and are threaded into the hub that
propeller shaft goes into. The result is terrific flexibility and vibration dampening in drive line.
The Federal Flexible Coupling is not a Universal Joint- Proper engine alignment should be done
with a fixed (rigid) shaft flange first- to allow Flexible Coupling to maximize the best efforts.
