The Ruland Four beam coupling is engineered for precision applications requiring exceptional torque capacity and minimal backlash. Ideal for high-speed operations, it features a balanced design that reduces vibration, ensuring smooth performance up to 6,000 RPM. Crafted from a single piece of 7075 aluminum, this coupling guarantees a lightweight, durable solution that adheres to strict RoHS3 and REACH compliance standards. The innovative four beam design, equipped with dual sets of spiral cuts, enhances performance by accommodating larger body sizes than traditional single beam options. Manufactured in the USA under stringent quality controls, this product delivers reliable operation and is suitable for a variety of industrial applications, providing an expert combination of performance and longevity.
