Torsionally flexible coupling

Clamping ring hubs

• Torsionally flexible shaft coupling with integrated clamping system

• High smoothness of running, application up to a peripheral speed of 40 m/s

• For high friction torques (consider the selection in case of explosion protection use)

• Easy to assemble due to internal clamping screws

• Finish bore up to 0 50 mm according to ISO fit H7, from 0 55 mm according to ISO fit G7

Approved according to EC Standard 94/9/EC

The transmittable torques of the clamping connection consider the max. clearance with shaft fit k6 / bore H7, from 055 G7/m6. With bigger clearance the torque is reduced. For the stiffness calculation of the shaft/hollow shaft see KTR standard 45510 at our homepage www.ktr.com
