The Ruland Six beam coupling is engineered for precision and reliability in light duty power transmission applications. Machined from a single piece of 303 stainless steel, it combines strength with reduced windup and vibration, enabling high-performance coupling of a servo motor to a lead screw. Its zero-backlash design ensures optimal torque capacity while maintaining a balanced construction for operation at speeds up to 6,000 RPM. Manufactured in the USA under stringent quality controls, this coupling guarantees compliance with RoHS3 and REACH standards, making it a trustworthy choice for engineers seeking durable solutions.
