Product Description

The RULAND MANUFACTURING Disc Coupling (SKU MDCDK80-25-25-A, MPN MDCDK80-25-25-A) is a double disc coupling for keyed shafts with a 25 mm x 25 mm bore diameter and 79.4 mm OD. It features a round with keyway bore type, a two-piece design with center spacer, and is constructed from aluminum hubs with stainless steel discs. This metric coupling has same bore dimensions and is clamp-on style.

Frequently Asked Questions

What is a RULAND MANUFACTURING disc coupling used for?

A RULAND MANUFACTURING disc coupling connects two keyed shafts while compensating for misalignment. It is used in motion control, packaging, and automation equipment where zero backlash and high torsional stiffness are required. The stainless steel discs handle parallel, angular, and axial misalignment without wear.

What are the specifications of the RULAND MANUFACTURING MDCDK80-25-25-A disc coupling?

The RULAND MANUFACTURING MDCDK80-25-25-A is a double disc coupling with 25 mm x 25 mm bore diameter, 79.4 mm OD, round with keyway bore type, and clamp-on style. It has aluminum hubs, stainless steel discs, a two-piece design with center spacer, and is metric with same bore dimensions.

Where to buy a RULAND MANUFACTURING disc coupling worldwide?

3G Electric supplies the RULAND MANUFACTURING MDCDK80-25-25-A disc coupling worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this metric double disc coupling with keyway.

How to install a RULAND MANUFACTURING clamp-on disc coupling?

To install a RULAND MANUFACTURING clamp-on disc coupling, clean both shaft ends and the bores. Loosen the clamp screws, slide the coupling onto the shafts, align the keyways, and tighten the screws evenly to the manufacturer's torque specification. Ensure the center spacer is free to float for proper misalignment compensation.
