The Ruland Six beam coupling is designed for precision and reliability in light-duty power transmission applications, making it ideal for pairing servo motors with lead screws. Its robust construction utilises 7075 aluminium, providing a lightweight yet durable solution. The coupling features a unique clamp style, which ensures zero backlash and a balanced design that significantly reduces vibration during high-speed operations of up to 6,000 RPM. The incorporation of Nypatch anti-vibration hardware enhances the coupling's performance by ensuring consistent screw seating and preventing galling. Fabricated in the USA under stringent quality controls, this product adheres to both RoHS and REACH regulations, guaranteeing a commitment to safety and environmental standards.
