The Elastomeric Coupling is a non-lubricated flexible coupling with benefits such as long life, simple installation, wrap around design, rubber in compression, cushions shock loads, corrosion resistant, and dampens torsional vibrations. Simple installation of this coupling is a unique feature. Just mount the hubs, align the shafts and install the flexible element. Assembly is completely visible, with no hidden or hard to reach components. The flexible element can be replaced without disturbing foundation bolts or shaft alignment. Bore Ranges from 1/2″ to 5 3/8”.
