EKH Heavy Duty
Elastomer couplingsThe heavy-duty claw coupling from R+W Couplings, type EKH, is easy to assemble and disassemble. The precisely manufactured clamp hubs provide the claw coupling with a very smooth rotation. The entire construction ensures that this industrial coupling is free of play. Both axially and laterally built direction. The EKH coupling can be combined with various types of R+W elastomeric elements. All types of R+W elastomeric elements dampen vibrations and provide electrical insulation. For specific inquiries about claw couplings or other industrial couplings, please contact VARIODRIVE.
