The clamping bolts placed on the flange surface allow easy and quick mounting and dismounting. A pressure medium sealed inside of the sleeve is compressed by fastening the clamping bolt. By the compression of a pressure medium, the sleeve is pressured from inside to contract the shaft-side sleeve and enlarge the hub-side sleeve to fasten a shaft and hub through the sleeve. Compared with a mechanical-type fastening element, the number of bolts to be used is small. Also, a high-precision fastening is possible with no slotting. For the ETP-A-B type, a hexagon bolt is used for the clamping bolt. It can be assembled if there is not enough space in a thrust direction.
