ES2
Torque limitersThe ES2 safety coupling from R+W Couplings is highly reliable when it comes to transmitting torque. Additionally, the ES2 precision coupling features a compact and straightforward press-fit design. Thanks to the patented R+W design, this precision coupling is completely backlash-free. Due to the use of elastomer, it dampens vibrations, is wear-resistant, and the coupling is electrically insulating. The maximum torque of the ES2 coupling can also be manually adjusted using an adjustment wrench. This wrench can be ordered separately. For specific questions about safety couplings or other precision couplings, please contact VARIODRIVE.
