Frequently Asked Questions

What is a RULAND MANUFACTURING double disc coupling used for?

This RULAND MANUFACTURING double disc coupling connects two round shafts with different bore diameters (45 mm and 30 mm) while accommodating misalignment. It is commonly used in precision motion control, packaging, and automation equipment where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING MDCD80-45-30-A disc coupling?

The MDCD80-45-30-A has a 79.4 mm OD, clamp-on style, and aluminum hubs with stainless steel disc packs. It features two-piece assembly with a center spacer, metric sizing, and accommodates different bore dimensions of 45 mm and 30 mm. The coupling is designed for round shafts.

Where to buy RULAND MANUFACTURING disc couplings in worldwide?
