Simplified selection
Td = Ta × K (see below)
(1) Calculate torque Ta applied to the coupling based on the
motor output P and coupling operating rotation speed n.

In servo motor drive, multiply the service factor K=1.2 to 1.5
by the maximum torque of servo motor Ts.
Td = Ts × (1.2 to 1.5)

Td
(2) Calculate corrected torque Td applied to the coupling after
deciding the service factor K based on load conditions.
(5) Confirm if the required shaft diameter does not exceed the
maximum bore diameter of the selected size.
(3) Select a coupling size with permissible torque Tn that
becomes equal or greater than the corrected torque Td.
(4) Depending on the bore diameters, the coupling permissible
torque may be limited. Refer to the “Specification” and
“Standard bore diameter”.
The table indicates suitable sizes based on the rated output, rated torque and maximum torque of general-purpose servo motors. Since
torque characteristics of servo motors differ depending on the manufacturer, select the coupling size after confirming the specification of the
manufacturer.
