# Refer to the Formula Selection for larger standard couplings and to a Falk Representative for special purpose couplings.
* If required speed is not shown, use next lower listed or interpolate between those listed.
If required speed is over 3550 rpm, or under 7.5 rpm, refer to the FORMULA method of selection on page 9.
Those who have occasion to make numerous selections should contact the local Falk Representative for a Falk Coupling Selector.
