Product Description

The RULAND MANUFACTURING Motion Control Coupling (MPN DCD26-12-12-A) is a double disc coupling for round shafts with a 3/4 in x 3/4 in bore diameter and 1 5/8 in OD. It features a clamp-on design with two discs and a center spacer, constructed from aluminum hubs and stainless steel discs. This inch-sized coupling has same bore dimensions and is not keyed.

Frequently Asked Questions

What is a RULAND MANUFACTURING double disc coupling used for?

A RULAND MANUFACTURING double disc coupling connects two rotating shafts while compensating for misalignment. It is used in motion control applications such as servo motors, encoders, and precision positioning systems where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND DCD26-12-12-A coupling?

The RULAND DCD26-12-12-A is a double disc coupling with a 3/4 in x 3/4 in bore diameter, 1 5/8 in OD, and a round clamp-on design. It has aluminum hubs, stainless steel discs, two discs with a center spacer, and is inch-sized with same bore dimensions.

Where to buy a RULAND MANUFACTURING motion control coupling worldwide?

How to select a double disc coupling for a round shaft?

To select a double disc coupling, match the bore diameter to your shaft size, choose the outer diameter for torque capacity, and confirm the hub material (e.g., aluminum) and disc material (e.g., stainless steel) suit your environment. RULAND MANUFACTURING couplings offer clamp-on designs for secure fit.

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.
