Information about static and dynamic torsional stiffness as well as max. possible misalignment go to

1 Nm = 8,85 in lbs

** Maximum transferable torque of the clamping hub depends on the bore diameters (bore/shaft clearance 0,01 mm to 0,05 mm shaft oiled)

Higher torque through additional key possible.
