R+W Coupling

Precision Couplings, Industrial Couplings, Integrated Sensor

The Ultimate Coupling Worldwide.

RW Coupling Logo

R+W Coupling offers state-of-the-art flexible shaft couplings, motor couplings, and line shafts for any precision application: backlash-free torque limiters, torsionally rigid metal bellows couplings, vibration dampening elastomer jaw-type couplings, compact miniature couplings, flexible servo couplings, axial zero backlash linear couplings, and high-quality line shafts.


R+W couplings fulfil the highest requirements and they are wear- and maintenance-free. The R+W headquarter is in Klingenberg, Germany with two branches in the USA, Italy and China. R+W is represented in more than 50 countries worldwide.


All motor, shaft, and servo couplings, as well as torque limiters and line shafts are torsion resistant, with zero backlash. Every shaft coupling and line shaft is also available in stainless steel. CAD drawing files of every shaft coupling, torque limiter, and line shaft are available to download at no cost.
