The Ruland six beam coupling ensures effective torque transmission while accommodating misalignment, making it an essential component for various motion control systems and applications.
Machined from 7075 aluminium for enhanced lightweight and low inertia
Features two sets of three spiral cuts for increased misalignment capability compared to other series
Houses a reference mark on the outer diameter for easy identification of the larger bore
All hardware is metric and exceeds DIN 912 12.9 standards for maximum torque capabilities
