SERIES: TYPE-TWN (TWN 105 & OVER)

Pin and Bush Coupling, Type-TWN

The Type-TWN Pin and Bush Coupling operates with high-tensile coupling bolts and elastomeric rubber bushes fitted over the pins. Pins are rigidly fastened with nuts to one flange half and kept loose in the mating flange pockets. The two halves are dissimilar in construction, designed to connect shafts experiencing small parallel, angular, or axial misalignments while effectively absorbing operational shocks and vibrations.
