The 100:1 Phase Adjuster Coupling is a multi-function component with unique capabilities. As a coupling it makes it easy to adjust the phase relationship between two shafts. As a component mount, it makes it easy to adjust the phase relationship between shaft and a mounted component.

Phase adjustment is accomplished when the drive system is stopped. Adjustments are made by hand in either direction by adjusting the knurled outer ring producing infinitely variable relative rotation of the hubs through a 100:1 reduction ratio.
