The Ruland Clamp Double Disc Coupling is engineered for precision and reliability in high-speed applications, providing zero-backlash performance in a lightweight, compact design. Crafted from high-quality aluminium, this coupling features a unique double disc configuration, allowing each disc to flex independently and effectively accommodate various types of misalignment. Ideal for demanding environments, it is capable of operating at speeds up to 10,000 RPM while maintaining low inertia. Rigorous manufacturing processes ensure every unit meets stringent standards, making it the perfect choice for stepper and servo applications across semiconductor, solar, and machine tool industries.
