Industrial Diaphragm Coupling Characteristics
Excellent Rotordynamics thanks to
lightweight design
low and definable restorative forces
no self-generated vibrations
low overhung moment
high balancing quality
No maintenance and repair requirements, because they...
are wear-free
need no lubrication
are frictionless (continuous diaphragm element)
Low heat generation and turbulence, due to
small bolts and screws
small diaphragm diameter

JM I Type Industrial Coupling
The JM I Type coupling is a 6 bolt single flex plane coupling which consists of two hubs and one
disc pack kit. It is only suitable for the specified axial and angular misalignment and does not
accommodate parallel misalignment. It is often combined with solid shafts to make floating shaft
couplings.
