KTR Corporation Backlash-Free Servo Coupling TOOLFLEX® CF

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 Extremely short design 25 % higher torques possible compared to type M or type S High torsional stiffness Backlash-free, torsionally stiff Maintenance-free Subject to welded connection suitable for high temperatures (max. 280° C) Particularly suitable for the use on gearboxes Flange-shaft connection Optionally available as type M (6 section bellows) and S (4 section bellows, short design) Torques from 35 – 340 Nm Available as special design with 1, 2 or 3 section bellows
