Optionally available with short bellow with 4 shafts (type S) or bellow with 6 shafts (type M)
The connection between bellow and hub is guaranteed by three different designs, dependent on the size. As for size 5 to size 12 the bellow is glued to the coupling hub, therefore ambient temperatures from -30° C to +100° C are permissible for these TOOLFLEX sizes. As for size 16 to size 45 the bellow-shaft connection is guaranteed by a flanged connection making sure for a torque transmission with each single bellow layer. The bellow-hub connection of the TOOLFLEX 55 and 65 is guaranteed through a welding connection.
