CEC Composite Couplings from MSC

[Travis Covington]

I was wondering if any one had some info on these couplers

We are having some drivetrain problems with our 4-motor 2 speed transmission (technokat design used last year/this year) and am looking to use a flex coupling to solve the problems (some misalignment, and some shock loading)

We saw the CEC composite couplings in MSC page 3558 here CEC Couplings

The problem is we need a coupling to withstand around 250 inch-lbs of torque, and from what i see here they only offer a 1/2 inch bore or larger with that torque rating. We need a 3/8 inch bore.

The reason for these CEC couplings is weight. Currently we are right near the limit, and we cant really purchase a love-joy coupling (at 1.5lbs a piece) because that would take us over the limit.

Thanks for the help.
