** Maximum transferable torque of the clamping hub depends
on the bore diameters (bore/shaft clearance 0,01 mm to 0,05 mm shaft
oiled)
Information about static and dynamic torsional stiffness as well as
max.
possible misalignment go to
1 Nm = 8,85 in lbs
Higher torque through additional key possible.
