I specified one of these (much smaller) to replace a clutch-type coupling on the input to a ball mill gearbox and it worked out very well. Never had a problem with it and the rubber elements were easy to change. But I assume the larger sizes would cost a lot more than a grid-flex. The ball mill (that we used the Max-C on) had a large gear ...
