Backlash-free, metal bellow-type coupling
Ambient temperatures from up to +200° C possible (dependent on size)
Torques from 0.1 up to 600 Nm
Couplings for power transmission, automation, medical technology, packaging technology, machine tools
TOOLFLEX® is a torsionally stiff, flexible metal bellow coupling with a bellow from stainless steel and coupling hubs from aluminium (in size 55 and 65 as well as with type KN the coupling hubs are from steel). The metal bellow compensates perfectly for axial, radial and angular displacements. At the same time its geometric shape allows for high torsional stiffness and a low mass moment of inertia.
In addition it is resistant to media influences and critical operating conditions. For different applications and assemblies the TOOLFLEX offers various hub designs as well as two different bellow lengths. The combination of these single parts forms one type.
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.
