The Ruland Four beam coupling is engineered for precision and reliability in high-speed applications up to 6,000 RPM. Designed from a singular piece of 7075 aluminum, it provides enhanced torque capacity and reduced windup, distinguishing itself from traditional single beam couplings. The coupling features a zero-backlash design, ensuring that vibration is minimized, making it ideal for applications demanding high performance. With its combined characteristics of lightweight construction and robust durability, this coupling supports both angular and parallel misalignment, cementing its status as a versatile solution for various engineering needs. Manufactured under strict quality controls in the USA, its compliance with RoHS3 and REACH standards further underscores its commitment to both performance and safety.
