Shaft Rating (Nm)
Example:
Application max speed 10000rpm
Torsion shaft rating 40Nm
Estimated coupling mass 0.75kg
Nc0.5kg = 10000
0.75 = 12247rpm
0.5
The max allowable coupling C of G from location
face read off chart is 18mm.
Note: Bi-directional ET’s can run heavier couplings, contact Torquemeters for further details.
