The Ruland Six beam coupling delivers exceptional performance in light-duty power transmission applications. It features a robust design machined from a single piece of 303 stainless steel, ensuring reliability and longevity. The product is specifically engineered to eliminate backlash, offering precise motion control, making it ideal for coupling a servo motor to a lead screw. With its unique balanced design, it reduces vibration at high speeds of up to 6,000 RPM, granting increased efficiency during operation. The coupling's construction meets rigorous manufacturing standards, utilising North American sourced bar stock that is RoHS3 and REACH compliant, thus ensuring safety and environmental responsibility. Manufactured under strict quality controls in Marlborough, MA, this coupling promises not only performance but also peace of mind in demanding applications.
