Frequently Asked Questions

What is the RULAND MANUFACTURING MDCD19-6-4-A double disc coupling used for?

The RULAND MANUFACTURING MDCD19-6-4-A is a motion control coupling designed for precision positioning in automation, robotics, and servo systems. It connects two round shafts with different bore diameters (6 mm and 4 mm) while compensating for misalignment, using a zero-backlash double disc design with a center spacer.

What are the specifications of the RULAND MANUFACTURING MDCD19-6-4-A coupling?

The RULAND MANUFACTURING MDCD19-6-4-A is a metric double disc coupling with a 19.1 mm OD, clamp-on round hubs in aluminum, and stainless steel discs. It has two discs with a center spacer and accommodates different bore dimensions (6 mm x 4 mm). The hubs are aluminum and the discs are stainless steel.

Where to buy the RULAND MANUFACTURING MDCD19-6-4-A coupling worldwide?

You can source the RULAND MANUFACTURING MDCD19-6-4-A coupling through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine RULAND MANUFACTURING components.

How to select the correct RULAND MANUFACTURING double disc coupling for a motion control application?

To select the correct RULAND MANUFACTURING double disc coupling, match the bore diameters to your shaft sizes (e.g., 6 mm and 4 mm), ensure the OD fits your space envelope (19.1 mm), and choose the clamp-on style for secure attachment. Verify torque and misalignment ratings from the manufacturer's catalog for your specific load.
