The Ruland Six beam coupling is a meticulously engineered solution designed for light-duty power transmission applications. This coupling is made from a single piece of 7075 aluminium, ensuring high torque capacity with minimal windup. Ideal for connecting servo motors to lead screws, it delivers a zero-backlash performance that keeps vibrations at bay even at high speeds of up to 6,000 RPM. The coupling's robust construction, featuring spiral cuts for added durability, enables it to handle dynamic and static torque demands effectively. With its balanced design and proprietary manufacturing process, this coupling meets stringent industry standards, making it a reliable choice for precision machinery.
