Description

R+W disc pack couplings transmit torque across the disc pack assemblies purely by friction, thus avoiding stress concentration, backlash, and micro-movements resulting from transmitting torque across the shoulder bolts. This aids in approaching infinite life in addition to making the complete coupling assembly torsionally stiff. R+W disc pack couplings are shipped as individual components. Assembly is required.
