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