The Ruland Four beam coupling is designed for precision applications requiring exceptional torque and vibration control. Manufactured from robust 7075 aluminum, it showcases a set screw style with a unique balanced design, ensuring zero backlash even at high operational speeds of up to 6,000 RPM. Its finely engineered spiral cuts enable remarkable torque capacity and reduced wind-up, outperforming conventional single beam couplings. Ideal for high-speed assembly, the product is compliant with stringent standards and is manufactured in the USA under meticulous quality controls, making it a reliable choice for engineers and designers seeking durability and performance in their systems.

Crafted from lightweight 7075 aluminum for enhanced performance and low inertia

Zero-backlash design minimizes vibration and enhances accuracy during operation

Higher torque capacity achieved through innovative spiral cut engineering

Suitable for dynamic applications with angular and parallel misalignment tolerances

Compatible with standard metric hardware for easy integration into existing systems
