EK1 Heavy Duty
Elastomer couplingsThe heavy-duty claw coupling from R+W Couplings, type EK1, features an economical, robust design and is easy to assemble and disassemble. The concentrically shaped clamp hubs provide the claw coupling with a very smooth rotation. The press fit design and use of a keyway make this industrial coupling play-free. The EK1 claw 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.
