Information about static and dynamic torsional stiffness as well as max. possible misalignment. 1 Nm = 8,85 in lbs

** Maximum transferable torque of the clamping hub depends on the bore diameters

Higher torque through additional key possible.

Installation instruction

Mounting of the clamping hub: Slide the coupling on the shaft
ends, at the right axial position thighten the mounting screw to the
specified tightening torque as shown in the table ( column E1).

Mounting of the conical hub: After inserting the key into the keyway
of the motor shaft slide the coupling hub on the shaft. Check if
the conical hub has a proper seat on the shaft. Now the nut (3) can
be tightened on the motor shaft using the exact tightening torque
specified by the motor manufacturer.
