R+W Antriebselemente GmbH
R+W - THE EKH ELASTOMER INSERT COUPLING
For over 30 years, R+W Antriebselemente GmbH has been manufacturing couplings, torque limiters and shaft lines for the whole world from 0.05 Nm to 2000 kNm that could meet your needs. In addition to a wide range of products, we can also offer you special couplings totally adapted to your applications.
FOR MAXIMUM PRECISION AND DYNAMICS: ELASTOMER COUPLINGS FROM R+W
The main advantages of elastomeric couplings are: vibration absorption, pluggable, zero backlash and electrical insulation. They are used in the following areas: Control technology, machine tools, packaging machines, automation systems, printers, control and positioning equipment, general mechanical engineering, pumps and mixers or roller door motors: depending on their function, the areas of use of the elastomer coupling are as varied as your requirements.
