The Ruland High-performance double disc coupling designed for precise positioning applications. Engineered with an electrically isolating feature, this coupling excels in environments where reducing current transfer between connected components is crucial. Its unique double disc design comprises anodized aluminum hubs and stainless steel springs, allowing for individual disc movement that accommodates various misalignments while maintaining a zero-backlash operation. The coupling is particularly suited for high-speed applications, capable of handling speeds up to 10,000 RPM, and is built from high-quality materials sourced from North American mills, ensuring durability and compliance with industry standards. This coupling is ideal for sectors such as semiconductor, printing, and machine tools, where reliability and performance are paramount.

Electrically isolating to prevent current transfer between components
Lightweight design contributes to low inertial resistance
