EKH

Elastomer couplings

This R+W claw coupling of the EKH type is easy to assemble and disassemble due to its split clamping hubs. The concentrically machined clamping hubs give this precision coupling a very smooth rotation. The entire construction ensures that the claw coupling is free of play. The EKH coupling can be combined with different types of R+W elastomer stars. All types of R+W elastomer couplings dampen the vibrations and are electrically insulating, with the ATEX version being conductive. For specific questions about claw couplings, please contact VARIODRIVE.
