Ruland DCD26-12-8-A Double Disc Clamp Coupling 3/4 In X 1/2 In Bores - Twin Spring Coupling - Premium Power Transmission Couplings

They are made from black anodized aluminum hubs and multiple flat stainless steel disc springs. Double disc styles also include a center spacer allowing the coupling to accommodate all forms of misalignment including parallel. Combining aluminum hubs with stainless disc springs results in a lightweight, low inertia coupling that is well suited for precision applications found in a variety of industries including semiconductor, solar, printing, and machine tools. Ruland uses a balanced design to reduce vibration in high RPM applications of up to 10,000 PRM. Ruland disc couplings are carefully made from select bar stock sourced exclusively from North American mills and are machined to a fine burr-free finish. Hardware tests beyond DIN 912 12.9 standards for maximum torqueing capabilities. Ruland, founded in 1937, manufactures all products in our Marlborough, MA USA factory under strict controls using proprietary processes. Zero-backlash with anodized aluminum hubs for low inertia Balanced design reduces vibration at speeds up to 10,000 RPM Double disc style accommodates all forms of misalignment and is torsionally rigid making them well suited for precision positioning systems Hardware exceeds DIN 912 12.9 standards for maximum torque capabilities
