Product Description

The RULAND MANUFACTURING Disc Coupling (MPN MDCDK70-25-25-A) is a double disc coupling for keyed shafts with a 25 mm x 25 mm bore diameter and 69.9 mm OD. It features a round with keyway bore type, a clamp-on design, and a two-piece assembly with center spacer. The hubs are aluminum, the discs are stainless steel, and it is metric-sized with same bore dimensions.

Frequently Asked Questions

What is the RULAND MANUFACTURING Disc Coupling MDCDK70-25-25-A used for?

This double disc coupling connects two keyed shafts in motion-control applications such as servo drives, encoders, and linear actuators. It compensates for misalignment while transmitting torque smoothly. The stainless steel discs and aluminum hubs provide high torsional stiffness and corrosion resistance, making it suitable for precision industrial machinery.

What are the specifications of the RULAND MANUFACTURING MDCDK70-25-25-A disc coupling?

The coupling has a 25 mm x 25 mm bore diameter, 69.9 mm OD, round with keyway bore type, and clamp-on design. It is a two-piece assembly with center spacer, metric-sized with same bore dimensions. Hubs are aluminum, discs are stainless steel. Manufacturer part number is MDCDK70-25-25-A.
