Product Description

The RULAND MANUFACTURING Disc Coupling (MPN MDCDK70-30-30-A) is a double disc coupling for keyed shafts with 30 mm x 30 mm bore diameters, 69.9 mm OD, and a round with keyway bore type. It features a clamp-on design, an aluminum hub and center spacer, stainless steel discs, and a metric configuration with two discs and a center spacer.

Frequently Asked Questions

What is a RULAND MANUFACTURING disc coupling used for?

A RULAND MANUFACTURING disc coupling connects two keyed shafts while accommodating misalignment. It is used in motion control, packaging, and automation equipment where precision torque transmission and zero backlash are required. The double disc design with a center spacer handles parallel, angular, and axial misalignment.

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

The RULAND MANUFACTURING MDCDK70-30-30-A is a double disc coupling with 30 mm x 30 mm bore diameters, 69.9 mm OD, round with keyway bore type, and clamp-on design. It has an aluminum hub and center spacer, stainless steel discs, and metric configuration. It includes two discs with a center spacer.

Where to buy a RULAND MANUFACTURING disc coupling worldwide?

As a global industrial solutions provider, we handle full logistics and customs clearance to ensure your order arrives at your facility. Contact us for availability and lead time on the MDCDK70-30-30-A or other RULAND MANUFACTURING couplings.

How to select a RULAND MANUFACTURING disc coupling for keyed shafts?

To select a RULAND MANUFACTURING disc coupling, match the bore diameter to your shaft size (e.g., 30 mm x 30 mm), choose the bore type (round with keyway), and confirm the OD (69.9 mm) fits your space. Consider torque requirements and misalignment needs; the double disc design with center spacer handles higher misalignment than single disc types.

Used in

Common applications for RULAND MANUFACTURING
Automated packaging machinery — Ruland beam couplings (e.g., PSR20-8-5-A) for connecting servo motors to conveyor drive shafts.
CNC machine tools — Ruland rigid couplings (e.g., CLX-4-4-A) for precise alignment of ball screw assemblies.
Robotic arm joints — Ruland Oldham coupling hubs (e.g., OSC16-6-A) for accommodating axial motion in end-effector drives.
Pump and compressor systems — Ruland stainless steel shaft collars (e.g., CL-3-ST) for securing impeller shafts.
Printing press rollers — Ruland clamp-on beam couplings (e.g., PCR18-8-8-A) for synchronizing roller rotation with minimal backlash.
Material handling conveyors — Ruland set screw couplings (e.g., PSMR29-7-7-A) for linking gearboxes to drive rollers.
