EKL

Elastomer couplings

This very compact R+W claw coupling of the EKL type is easy to assemble and disassemble. The concentrically machined clamping hubs give the coupling a very smooth concentricity. The press fit design ensures that this precision coupling is free from play. The EKL coupling can be combined with various types of R+W elastomer star elements. All types of R+W elastomer star elements dampen vibrations and are electrically insulating, with the ATEX version being conductive. For specific questions about claw couplings, please contact VARIODRIVE.
