The Ruland Six beam coupling is engineered for precision and reliability, making it an ideal choice for light-duty power transmission applications. Designed to connect a servo motor to a lead screw, it features a set screw style that enhances torque capacity while maintaining low windup. The coupling is crafted from robust 7075 aluminium and boasts a balanced configuration, ensuring minimal vibration even at high rotational speeds of up to 6,000 RPM. Its unique spiral cuts enable exceptional performance in demanding environments, while the zero-backlash feature addresses the need for precise movement in mechanical systems. Manufactured in the USA with stringent quality controls, this coupling is suitable for industries requiring high standards of durability and compliance.

Zero-backlash functionality improves system accuracy

Manufactured from RoHS3 and REACH compliant materials

Compatible with metric hardware for international applications

Installation requires only a 2.5 mm hex key for convenience

High torque ratings ensure reliable performance in dynamic settings

Designed to withstand extreme temperatures ranging from -40°F to 225°F
