EK6 Heavy Duty

Elastomer couplings

The heavy-duty claw coupling from R+W Couplings, type EK6, with tapered clamp hubs self-centers on the shaft. Due to its press fit design and high clamping force, this industrial coupling is completely free of play. The EK6 claw coupling can be combined with various types of R+W elastomeric elements. All types of R+W elastomeric elements dampen vibrations and are electrically insulating. For specific inquiries about claw couplings or other industrial couplings, please contact VARIODRIVE.
