Frequently Asked Questions

What is a RULAND MANUFACTURING double disc coupling used for?

A RULAND MANUFACTURING double disc coupling, like the MDCD25-6-6-A, is used in motion control applications to connect two rotating shafts while compensating for misalignment. It provides high torsional stiffness and zero backlash, making it ideal for precision positioning systems, servo motors, and encoders.

What are the specifications of the RULAND MANUFACTURING MDCD25-6-6-A coupling?

The RULAND MANUFACTURING MDCD25-6-6-A is a double disc coupling with a 6 mm x 6 mm bore diameter, 25.4 mm OD, and a round clamp-on design. It has aluminum hubs with stainless steel discs, a two-piece assembly with a center spacer, and is metric with same bore dimensions.

Where to buy a RULAND MANUFACTURING MDCD25-6-6-A coupling worldwide?

You can source the RULAND MANUFACTURING MDCD25-6-6-A coupling from 3G Electric, which handles full logistics, customs clearance, and delivery to worldwide destinations. As a global industrial solutions provider, 3G Electric supplies genuine RULAND MANUFACTURING motion control couplings for demanding applications.

How to install a RULAND MANUFACTURING clamp-on coupling?

To install a RULAND MANUFACTURING clamp-on coupling, first clean the shaft ends and bore. Loosen the clamp screws, slide the coupling onto both shafts, and align the components. Tighten the screws evenly to the manufacturer's recommended torque using a torque wrench to avoid damaging the stainless steel discs.
