Frequently Asked Questions

What is the RULAND MANUFACTURING disc coupling used for?

This double disc coupling connects two keyed shafts with different bore diameters (30 mm and 25 mm) in motion-control applications. It compensates for misalignment while transmitting torque, making it suitable for precision machinery, robotics, and automation systems where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING MDCDK70-30-25-A?

The coupling has a 69.9 mm OD, round with keyway bore type, and clamp-on design. It features an aluminum hub and center spacer with stainless steel discs. It accommodates different bore dimensions (30 mm and 25 mm) and uses metric sizing. The manufacturer part number is MDCDK70-30-25-A.

Where to buy the RULAND MANUFACTURING disc coupling worldwide?

3G Electric supplies the RULAND MANUFACTURING MDCDK70-30-25-A disc coupling worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select the correct RULAND MANUFACTURING disc coupling for keyed shafts?

Match the bore diameters to your shaft sizes (here 30 mm and 25 mm) and ensure the keyway dimensions align. Verify the OD (69.9 mm) fits your space constraints. Choose the clamp-on style for secure shaft attachment without marring. RULAND MANUFACTURING couplings are designed for precision alignment compensation.
