The unique design of this coupling eliminates the need to
use rubber hose or universal adapters to attach your stirrer shafts to overhead
stir motors. Coupling incorporates a unique helical S.S. spring permitting up
to 1/4” of offset misalignment and 45° of angular misalignment. Coupling is
rated for 24 in-lbs of torque without the backlash normally associated with
common coil springs.
Lower portion of coupling has a nylon adapter with a one
piece collar for attachment to 10mm stir shafts. Upper adapters permit the
coupling to be used with a standard Jacobs style 3-jaw chuck. Overall length of
the coupling is 4”. Supplied complete with an allen wrench set.
