Know your application Nomination Torque
Determine the Nominal Torque rating in Nm of
the application from power & speed, by the
following formulae:
Know your application service factor
Determine the appropriate service factor of
your application by referring the adjacent table.
Calculate coupling selection torque
The coupling selection torque can be calculated
by multiplying the service factor to the nominal
torque.
Select coupling on the basis of torque
rating:
Considering the calculated coupling selection
Torque,
select the coupling with a rated torque equal
to or greater than your calculated torque.
Check for the maximum Bore capacity :
If the coupling size is inadequate for want
of a larger bore capacity, check for the adaptor
style 2. Couplings with a combination of style
1 and style 2 are also available.
Check on other parameters :
Check that the selected coupling is appropriate
for maximum speed, misalignment and spacer lengths.

turbines etc.)
