EK1 | Elastomer Coupling

With Key-Way Connection

The EK1 is designed with two coupling hubs that are concentrically machined with curved jaws and one elastomer insert that is made with precision molded, wear resistant, and thermally stable polymer.
The operating temperature range depends on the Elastomer insert that is used with the coupling.
See table for rated operating speeds. *2.5 Balance grade available upon request.
Coupling hubs up to series 450 are made of high strength aluminum, series 800 and up are steel.
This is an economical solution with vibration damping and electrically isolating properties. It offers low or zero backlash performance with its key-way connection and press fit composition.
