The Ruland Four beam coupling is a precision-engineered solution designed for high-performance applications. Featuring a robust clamp style, it is constructed from a single piece of 7075 aluminum, ensuring both durability and lightweight performance. The unique design incorporates two sets of spiral cuts that enhance torque capacity and minimize windup, making it ideal for precision motion control systems. Capable of handling high speeds up to 6,000 RPM, this coupling offers exceptional balance, resulting in reduced vibrations that can improve system longevity and reliability. With its zero-backlash feature and adherence to stringent manufacturing standards, this coupling is perfect for users seeking reliable performance in demanding environments.
