Ruland MDCD19-8-6-A 2024 or 7075 Aluminum Hubs Disc Coupling, Double Disc Clamp Style, 8 mm x 6 mm Bores, 19.1 mm OD, 30.2 mm Length

                Ruland disc couplings are zero-backlash, torsionally stiff, and have a balanced design. They are manufactured in single disc styles for compact installations and double disc styles for increased misalignment capabilities. 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. They are well suited for high precision positioning systems found in semiconductor, solar, printing, and machine tools.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. Disc couplings are a simple assembly with few moving parts reducing the risk for coupling failure and backlash. 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. Disc couplings are RoHS2 and REACH compliant.
