Product Description

The RULAND MANUFACTURING Motion Control Coupling (SKU MDCD19-6-4-A, MPN MDCD19-6-4-A) is a double disc coupling for round shafts with a 6 mm x 4 mm bore diameter and 19.1 mm OD. It features a clamp-on design with two discs and a center spacer, constructed from aluminum hubs and stainless steel discs. This metric coupling accommodates different bore dimensions and is designed for motion control applications.

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.
