EK1

Elastomer couplings

The EK1 type claw coupling from R+W Couplings features an economical, robust design and is easy to assemble and disassemble. The concentrically machined clamping hubs give the coupling a very smooth runout. The press-fit design and use of a keyway make this precision coupling low in play. The EK1 coupling can be combined with various types of R+W elastomer stars. All types of R+W elastomer stars dampen the vibrations and are electrically insulating, with the ATEX version being conductive. For specific inquiries about claw couplings, please contact VARIODRIVE.
