DYNAFLEX ELASTOMERIC FLEXIBLE COUPLINGS
Selection Guide
This selection guide can be used to determine the size
and series coupling to suit your general requirements.
Final selection of the specifi c coupling to satisfy all of
the application requirements generally necessitates
a system engineering analysis. These computerized
analyses of torsional systems can be provided by LORD
Corporation’s Engineering Department.

X Series - Type I Housing Couplings (0075, 0150,
0200, 0300) (With Tapered Inner Member)
Note: The LCD-0075-13 design is the same as the “20 Series” except
the outer member fl ange O.D. is very small.

XX Series - Type II Housing Couplings (0075,
0150, 0200, 0300) (With Flanged Inner Member)
Figure 6 – Typical Dynafl ex LCD Coupling
01 Series - Type III Housing Couplings (400 hp
and above)
Note: 0400-04 has tapered inner member. 0600 and above do not have
tapered inner member.

Application Note: Sustained operation at torsional resonance can
produce vibratory torques which might cause damage to the coupling
and other driveline components. Please consult LORD Engineering for
application review and approval.
