The Lovejoy Oldham coupling is a precision engineered, torsionally stiff, three-piece coupling suitable for a great many
applications ranging from incremental control of fluid valves to highly dynamic drives in closed loop servo systems. It
accommodates misalignment mechanically through a floating disc that engages tenons machined out of the hubs. As the
coupling rotates, the floating disc aligns with eachhub alternately to an extent demanded by the alignment error.
