The Ruland Advanced clamp-style four beam coupling designed to seamlessly connect shafts while accommodating misalignments. Crafted from a solid piece of 7075 aluminum, this coupling excels in providing a robust, lightweight solution ideal for high-speed applications, operating effectively at speeds up to 6,000 RPM. The unique design features two sets of spiral cuts, which enhance torque capacity and minimize windup, ensuring reliable performance in demanding environments. This coupling not only boasts a zero-backlash feature, which guarantees precise motion transfer without play but also incorporates a balanced construction that reduces vibration, enhancing the overall efficiency of your system. It is specifically manufactured in the USA with strict quality controls, using materials sourced from North American mills to meet stringent compliance standards.
