The Ruland Six beam coupling is designed to provide exceptional performance in light-duty power transmission applications. Its robust construction features a clamp style that accommodates bores of 18mm and 17mm, ensuring a secure and reliable connection between shafts. Engineered from a single piece of 7075 aluminium, this coupling is not only lightweight but also strong, exhibiting low inertia for enhanced efficiency. With the ability to handle speeds of up to 6,000 RPM, it promotes a balanced design that minimises vibration, contributing to superior operational stability. The inclusion of Nypatch anti-vibration hardware enhances bolt retention and prevents galling, further elevating the product’s reliability. Manufactured in North America under stringent controls, this coupling adheres to high standards of quality and compliance, making it a trusted choice for effective and efficient motion control applications.
