The Ruland Four beam coupling is engineered for precision and performance, ideal for applications requiring high torque and zero backlash. With a robust construction from a single piece of RoHS and REACH compliant aluminum, it guarantees durability while maintaining a lightweight profile. The design incorporates two sets of spiral cuts, providing enhanced torque capacity and reduced wind-up, making it perfect for high-speed operations of up to 6,000 RPM. This coupling ensures optimal alignment and minimal vibration, resulting in a smoother operational experience. Manufactured under stringent controls in the USA, it meets the highest standards of quality and reliability.

Machined from high-quality 7075 aluminum for a lightweight structure

Designed to minimize vibration during high-speed applications

Zero-backlash feature enhances operational efficiency

Suitable for angular and parallel misalignment allowances
