The Ruland Four beam coupling presents an innovative solution for precision coupling needs, crafted from high-grade 7075 aluminum to ensure lightweight durability. This component excels in applications requiring optimal torque capacity and minimal windup thanks to its unique four beam design, promising a balanced operation that significantly reduces vibration even at high speeds up to 6,000 RPM. Every unit undergoes stringent manufacturing protocols at a facility in Marlborough, Massachusetts, ensuring quality and compliance with industry standards, including RoHS3 and REACH. With its zero-backlash design, this coupling is ideal for dynamic applications where accuracy and reliability are paramount, catering perfectly to the demands of modern engineering projects.

Machined from a single piece of 7075 aluminum for enhanced structural integrity
Zero-backlash design ensures a precise connection for critical applications
Supports angular misalignment of up to 3° for flexible installation
Dynamic torque ratings are tailored for optimal performance during operation
Lightweight build reduces overall assembly inertia, improving system responsiveness
