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.
