The Ruland Clamp Double Disc Coupling is designed to tackle the challenges of misalignment while ensuring seamless torque transmission. Made from high-quality aluminium, this coupling balances lightweight construction with robust durability, making it ideal for demanding applications such as semiconductor and machine tool systems. Engineered for low inertia, it efficiently supports operations at speeds of up to 10,000 RPM without generating backlash, enabling precise and controlled movements. The advanced design features anodised aluminium hubs and stainless steel disc springs that individually flex to accommodate various alignment conditions, setting a new standard for reliability and performance in motion control applications. Manufactured under stringent quality controls in the USA, this coupling adheres to all essential compliance requirements and is built to endure the rigours of industrial environments.
