Frequently Asked Questions

What is the RULAND MANUFACTURING MDCD80-30-25-A disc coupling used for?

The RULAND MANUFACTURING MDCD80-30-25-A double disc coupling connects two round shafts with different bore diameters (30 mm and 25 mm) while compensating for misalignment. It is commonly used in precision motion control, servo systems, and industrial automation where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING MDCD80-30-25-A disc coupling?

This coupling has a 30 mm x 25 mm bore diameter, 79.4 mm OD, and a clamp-on design. It features an aluminum hub and center spacer with stainless steel disc packs. The coupling is metric, round, and includes two discs with a center spacer for accommodating different bore dimensions.

Where to buy the RULAND MANUFACTURING MDCD80-30-25-A disc coupling worldwide?
