The Ruland Innovative clamp double disc coupling designed to accommodate various misalignment types while ensuring a zero-backlash operation. Engineered from high-quality anodized aluminum, this coupling features a unique design that includes stainless steel disc springs and an acetal center spacer to prevent electrical transfer between components. With a lightweight construction and low inertia, it excels in high-speed applications, achieving optimal performance at speeds of up to 10,000 RPM. This coupling is perfect for precision positioning in sectors such as semiconductor, solar, and machine tool applications. Furthermore, its robust manufacturing from solid bar stock sourced from North American mills ensures compliance with RoHS and REACH standards, affirming its reliability for diverse industrial applications.
Electrically isolating design prevents unintended current transfer
Balanced structure minimises vibration in high-speed environments
