Simple construction sandwiches rubber buffer between two hubs
These couplings have simpler designs that sandwich a rubber buffer (nitrile rubber) between two hubs. The hub is lightweight, being made of aluminum alloy. The simple construction sandwiches a spider (rubber buffer) between hubs, so the coupling is easily mounted or removed by moving the device in the axial direction. Mounting on a shaft is easy. Simply hold a straight-edge to the hub periphery to center it.

Simply hold a straight-edge to the hub periphery to center it. One source of appeal is that its simple construction means lower cost.
