It features a clamp-on design, a two-piece assembly with center spacer, and is constructed from aluminum hubs with stainless steel discs. This metric coupling has same bore dimensions and is designed for motion control applications.
Frequently Asked Questions
What is the RULAND MANUFACTURING MDCD19-4-4-A double disc coupling used for?
The RULAND MANUFACTURING MDCD19-4-4-A is a motion control coupling designed for precision shaft alignment in servo, stepper, and encoder applications. It compensates for parallel, angular, and axial misalignment while transmitting torque smoothly. Common in CNC machinery, robotics, and packaging equipment, it ensures zero backlash and high torsional stiffness.
What are the specifications of the RULAND MANUFACTURING MDCD19-4-4-A coupling?
This double disc coupling has a 4 mm x 4 mm bore diameter, 19.1 mm OD, and a round clamp-on design. It features aluminum hubs with stainless steel discs, a two-piece assembly with center spacer, and metric dimensions. The same bore dimensions on both ends suit motion control systems requiring precise torque transmission.
