Ruland Disc, 57.2mm Outside Diameter, 16 mm, 20 mm Bore, 78.2mm Length Flexible Coupling

The Ruland Electrically isolating clamp double disc coupling is meticulously designed for precision and reliability in high-speed applications. With a robust construction made from anodized aluminum and featuring stainless steel disc springs, this coupling effectively accommodates various types of misalignment without incurring backlash. Its lightweight design enables operation at speeds reaching up to 10,000 RPM, while the unique acetal center spacer ensures that electrical currents do not transfer between the motor and driven components. Being manufactured under stringent controls in Marlborough, MA, this coupling exemplifies quality craftsmanship and attention to detail, making it an ideal choice for industries such as semiconductor, solar, and machine tool applications.
