The Ruland Six beam coupling is expertly designed to provide a robust and precise connection between shafts in light duty power transmission applications. This product boasts a clamp style mechanism for enhanced security and zero-backlash performance, ensuring optimal torque transfer without compromising on precision. Machined from a single piece of 7075 aluminium, it offers a combination of lightweight construction and remarkable strength, making it ideal for high-speed environments up to 6,000 RPM. The innovative spiral cuts enhance torque capacity while minimising windup, further elevating its effectiveness in dynamic applications. Manufactured under stringent quality controls in Marlborough, MA, this coupling is compliant with RoHS3 and REACH regulations, ensuring both safety and reliability. Each unit includes Nypatch anti-vibration hardware for improved screw seating and installation repeatability, a testament to its engineering excellence.
