KTR Corporation Backlash-Free, Torsionally Stiff Metal Bellow-Type Coupling TOOLFLEX® Type KN

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. Product features Integrated clamping system with taper-clamping ring hub Non-positive bellow-hub connection Optionally available with short bellow with 4 shafts (type S) or bellow with 6 shafts (type M) Optimal properties of concentric running due to symmetric arrangement Torques from 35 to 340 Nm High friction torques
