Product Description

The RULAND MANUFACTURING Motion Control Coupling (MPN MDCD19-5-4-A) is a double disc coupling for round shafts with a 5 mm x 4 mm bore diameter and 19.1 mm OD. It features a clamp-on design, two discs with a center spacer, and is constructed from aluminum with stainless steel hardware. This metric coupling accommodates different bore dimensions.

Frequently Asked Questions

What is the RULAND MANUFACTURING MDCD19-5-4-A double disc coupling used for?

The RULAND MANUFACTURING MDCD19-5-4-A is a motion control coupling designed for precision shaft alignment in automation, packaging, and robotics. Its double disc design with a center spacer accommodates parallel and angular misalignment while transmitting torque smoothly between a 5 mm and 4 mm bore shaft.

What are the specifications of the RULAND MANUFACTURING MDCD19-5-4-A coupling?

This coupling has a 19.1 mm OD, 5 mm x 4 mm bore diameters, and a round clamp-on style. It is made of aluminum with stainless steel hardware, includes two discs with a center spacer, and is metric. The RULAND MANUFACTURING part number is MDCD19-5-4-A.

Where to buy the RULAND MANUFACTURING MDCD19-5-4-A coupling worldwide?
