Ruland MDCD41-20-12-A 2024 or 7075 Aluminum Hubs Disc Coupling
Ruland MDCD41-20-12-A is a clamp double disc coupling with 20mm x 12mm bores, 41.3mm OD, and 55.0mm length. It is zero-backlash and has a balanced design for reduced vibration at high speeds. The double disc design is comprised of two anodized aluminum hubs, two sets of thin stainless steel disc springs, and a center spacer allowing each disc to bend individually and accommodate all types of misalignment. MDCD41-20-12-A is lightweight and has low inertia making it well suited for applications with speeds up to 10,000 RPM. Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities. Ruland manufactures MDCD41-20-12-A to be torisionally rigid and an excellent fit for precise positioning stepper servo applications commonly found in semiconductor, solar, printing, machine tool, and test and measurement systems. It is machined from solid bar stock that is sourced exclusively from North American mills and RoHS3 and REACH compliant. MDCD41-20-12-A is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.

- Ruland oldham couplings have a zero-backlash balanced design for reduced vibration at speeds up to 4,500 RPM. Keyway is used on this coupling for additional torque transmission capabilities and to prevent slippage on the shaft.
- Can accommodate high amounts of parallel misalignment (up to 10% of the hub OD). Acts as a mechanical fuse stopping power transmission during a torque overload.
- User can combine clamp or set screw hub with inch, metric, keyed, or keyless bore for a high level of customization. Proprietary hub machining process for smooth interaction between the hub and disk allowing for significantly longer life
- Made from high strength 2024 aluminum with a black anodized finish for light weight and low inertia.
