Product Description

The RULAND MANUFACTURING Motion Control Coupling (MPN MDCD25-8-8-A) is a double disc coupling for round shafts with 8 mm x 8 mm bore diameters and a 25.4 mm OD. It features a clamp-on design with two discs and a center spacer, constructed from aluminum hubs and a stainless steel disc pack. This metric coupling has same bore dimensions and is designed for motion control applications.

Frequently Asked Questions

What is a RULAND MANUFACTURING double disc coupling used for?

A RULAND MANUFACTURING double disc coupling is used in motion control applications to connect two rotating shafts while compensating for misalignment. It transmits torque smoothly with zero backlash, making it ideal for precision positioning systems, encoders, and servo drives.

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.
