The Ruland Clamp style six beam coupling is designed to provide exceptional torque capacity and reduced backlash, making it ideal for light duty power transmission applications. Constructed from a single piece of 7075 aluminium, this coupling features three spiral cuts that enhance its ability to handle higher loads while maintaining precision. With a balanced design and capable of operating at speeds up to 6,000 RPM, it ensures minimal vibration during high-speed operations. The integration of Nypatch anti-vibration hardware further optimises performance by enabling consistent screw installations and preventing galling. Manufactured in Marlborough, MA, this product adheres to strict quality standards and offers a reliable solution for connecting servo motors to lead screws with ease.
