Product Description

The RULAND MANUFACTURING Disc Coupling (MPN DCDK50-28-28-A) is a double disc coupling for keyed shafts with a 1 3/4 in x 1 3/4 in bore diameter and a 3 1/8 in OD. It features a round with keyway bore type, an aluminum hub and center spacer, and stainless steel disc packs. The coupling has 2 discs with a center spacer and is designed for inch-dimension shafts with same bore dimensions.

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 disc packs handle parallel and angular misalignment without wear.

What are the specifications of the RULAND MANUFACTURING DCDK50-28-28-A disc coupling?

The RULAND MANUFACTURING DCDK50-28-28-A is a double disc coupling with a 1 3/4 in x 1 3/4 in bore diameter, 3 1/8 in OD, and round with keyway bore type. It has an aluminum hub and center spacer, stainless steel disc packs, and 2 discs with a center spacer for inch-dimension shafts.

Where to buy a RULAND MANUFACTURING disc coupling worldwide?

3G Electric supplies and delivers the RULAND MANUFACTURING DCDK50-28-28-A 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.

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

To select a RULAND MANUFACTURING disc coupling, match the bore diameter and keyway to your shaft dimensions. For the DCDK50-28-28-A, both bores are 1 3/4 in with a round keyway. Consider the torque, speed, and misalignment requirements of your application. Aluminum hubs reduce inertia, while stainless steel disc packs provide corrosion resistance.

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.
