Ruland disc couplings are available in single and double disc styles with bore sizes ranging from 1/8" to 1 1/4" in the inch series and 3mm to 30mm in the metric series. A disc coupling is composed of two black anodized aluminum hubs, multiple flat stainless steel disc springs and a center spacer for double disc
styles. The center spacer is available in a choice of anodized aluminum or insulating acetal for electrical isolation. The thin discs allow for a substantial amount of angular and parallel misalignment between shafts, while remaining rigid under torque loads. The disc couplings, as a result, are a high performance motion control coupling with excellent high speed capabilities (up to 10,000 rpm), strength and torsional stiffness characteristics, and low inertia for today's highly responsive systems.
