    PRODUCT SPECIFICATIONS

    Ruland MDCD15-3/2.5D-3/2.5D-A is a d-bore double disc coupling with 3/2.5Dmm x 3/2.5Dmm bores, 15,0mmOD, and 23,8mm length. The d-bore allows for positive drive in applications where the coupling can not slip. 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. MDCD15-3/2.5D-3/2.5D-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 MDCD15-3/2.5D-3/2.5D-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. MDCD15-3/2.5D-3/2.5D-A is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.

    Product Notes

    Nota 1

    Stainless steel hubs are available upon request.

    Nota 2

    Torque ratings are at maximum misalignment.

    Nota 3

    Performance ratings are for guidance only. The user must determine suitability for a particular application.

    Nota 4

    Torque ratings for the couplings are based on the physical limitations/failure point of the disc springs. Under normal/typical conditions the hubs are capable of holding up to the rated torque of the disc springs. In some cases especially when the smallest standard bores are used or where shafts are undersized slippage on the shaft is possible below the rated torque of the disc springs. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance.
