There are different assembling options: Flange-flange: using two hubs type “CF” Flange-shaft: using one hub Trasco standard “GR” and one hub type ”CF” ® Shaft-shaft: using two hubs type “CFF”, allows the replacement of the elastic element without dismounting of either motor-machine or driven-machine.
