Part I of this article appeared in the October 2008 issue. It provided an overview and general classifi cations of power transmission couplings, along with selection and performance criteria for rigid couplings and misalignment-compensating couplings. Part II continues the discussion with selection and performance criteria for torsionally flexible and combination-purpose couplings.

Few would now argue that what some may have perceived just a few years ago as “Chicken Little” stories regarding the depletion of this country’s skilled manufacturing workforce are now in fact firmly based in stark reality.

The repair-versus-replace decision is quite complicated, depending upon variables such as rewind cost, severity of the failure, replacement motor purchase price and other factors.
