The Ruland Six beam coupling is designed for precision power transmission in light-duty applications. Combining superior features such as a balanced design and zero-backlash capability, this coupling ensures reduced vibration at high speeds, facilitating seamless operation in various mechanical setups. Its robust construction from a single piece of aluminium enhances durability while maintaining a lightweight profile, making it ideal for servo motors and lead screws. The coupling's unique spiral cut design significantly increases torque capacity and minimizes windup, thereby enabling efficient performance under demanding conditions. With strict manufacturing controls in place, this coupling meets rigorous industry standards and instils confidence in its operational integrity.
Zero-backlash technology assures precise movement without play
Can accommodate misalignments up to 3° angular, 0.38 mm parallel, and 0.25 mm axial
Designed for maximum speeds of up to 6,000 RPM, ensuring high efficiency
Four alloy steel screws provide secure attachment, enhancing reliability
Lightweight design contributes to overall system efficiency
