The 1-1/4" x 1-1/4" Steel (Black Oxide) 100:1 Phase Adjuster Coupling is a multi-function component designed to provide precise, hand-adjustable static phase adjustment between two shafts or between a shaft and a mounted component. Its 100:1 reduction ratio allows the knurled outer ring to produce fine, infinitely variable relative rotation of the hubs in either direction while the drive system is stopped. It can be used as a rigid shaft coupling or component mount, includes a standard keyway for secure torque transmission, and helps maintain shaft alignment for accurate positioning.
