Higher torsional rigidity than commodity style single-beam coupling. Machined from a single piece of aluminum or stainless steel with multiple spiral cuts for higher torsional stiffness and torque capabilities than single beam couplings. Accommodate parallel misalignment, angular misalignment and axial motion. Two sets of cuts around center member better accommodate parallel misalignment than single beam couplings. Aluminum couplings made from 7075 aluminum for long life and low inertia. Hardware is metric and exceeds industry standards for maximum torque capabilities. Manufactured by Ruland in our Marlborough, MA factory under strict controls using proprietary processes.
