Product Description

The RULAND MANUFACTURING Motion Control Coupling (MPN DCD12-5-5-A) is a double disc coupling for round shafts with a 5/16 in x 5/16 in bore diameter and 3/4 in OD. It features a clamp-on design, an aluminum hub and center spacer, and stainless steel discs. The coupling has two discs with a center spacer and is designed for inch-sized shafts with same bore dimensions.

Frequently Asked Questions

What is the RULAND MANUFACTURING DCD12-5-5-A double disc coupling used for?

The RULAND MANUFACTURING DCD12-5-5-A double disc coupling is used in motion control applications to connect two round shafts with 5/16 in bores. It accommodates misalignment while transmitting torque, making it suitable for precision automation, robotics, and servo systems where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING DCD12-5-5-A coupling?

The RULAND MANUFACTURING DCD12-5-5-A is a double disc coupling with a 5/16 in x 5/16 in bore diameter and 3/4 in OD. It has a round, clamp-on design with an aluminum hub and center spacer, plus stainless steel discs. It features two discs with a center spacer and is designed for inch-sized shafts with same bore dimensions.

Where to buy the RULAND MANUFACTURING DCD12-5-5-A coupling worldwide?

You can source the RULAND MANUFACTURING DCD12-5-5-A double disc coupling worldwide through 3G Electric. As a global industrial equipment distributor since 1990, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact 3G Electric for availability and lead time.

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

To select the correct RULAND MANUFACTURING double disc coupling, match the bore diameter to your shaft size—here 5/16 in for both ends. Verify the OD (3/4 in) fits your space, and choose the clamp-on style for secure attachment. Ensure the coupling material (aluminum hub, stainless steel discs) suits your environment and torque requirements.

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.
