EK6

Elastomer couplings

The EK6 type claw coupling from R+W Couplings with clamping ring self-centers on the shaft. Due to its press fit design and high clamping force, this precision coupling is completely backlash-free. The EK6 claw coupling can be combined with various types of R+W elastomer stars. All types of R+W elastomer stars dampen vibrations and are electrically insulating, with the ATEX version being conductive. For specific questions about claw couplings, please contact VARIODRIVE.
