Product Description

The RULAND MANUFACTURING Disc Coupling (MPN DCDK50-28-24-A) is a double disc coupling for keyed shafts with different bore dimensions of 1 3/4 in and 1 1/2 in, a 3 1/8 in OD, and a round with keyway bore type. It features an aluminum hub and center spacer, stainless steel discs, and a two-piece design with center spacer. This inch-sized coupling is designed for applications requiring zero backlash and high torsional stiffness.

Frequently Asked Questions

What is the RULAND MANUFACTURING disc coupling used for?

This double disc coupling connects two keyed shafts with different bore diameters (1 3/4 in and 1 1/2 in) in motion-control applications. It provides zero backlash and high torsional stiffness, making it suitable for precision positioning systems, servo drives, and packaging machinery where accurate torque transmission is critical.

What are the specifications of the RULAND DCDK50-28-24-A coupling?

The RULAND DCDK50-28-24-A is a double disc coupling with a 3 1/8 in OD, round with keyway bore type, and different bore dimensions of 1 3/4 in and 1 1/2 in. It features an aluminum hub and center spacer, stainless steel discs, and a two-piece design with center spacer. It is inch-sized.

Where to buy the RULAND disc coupling DCDK50-28-24-A worldwide?

How to select the right RULAND disc coupling for keyed shafts?

To select the correct RULAND disc coupling, match the bore diameters to your shaft sizes (here 1 3/4 in and 1 1/2 in), confirm the keyway type (round with keyway), and ensure the OD (3 1/8 in) fits your space. Consider torque requirements and misalignment needs; the double disc design with center spacer accommodates parallel offset.

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.
