Product Description

The RULAND MANUFACTURING Disc Coupling (MPN DCD50-1-1/4"-25MM-A) is a double disc coupling for round shafts with a 1 1/4 in x 25 mm bore diameter and 3 1/8 in OD. It features a clamp-on design, an aluminum hub and center spacer, and stainless steel discs. This inch-to-metric bore coupling accommodates different bore dimensions and includes two discs with a center spacer.

Frequently Asked Questions

What is the RULAND MANUFACTURING DCD50-1-1/4"-25MM-A disc coupling used for?

This double disc coupling connects round shafts with different bore sizes (1 1/4 in and 25 mm) in motion-control applications. It compensates for misalignment while transmitting torque, making it suitable for precision machinery, robotics, and automation systems where reliable shaft coupling is required.

What are the specifications of the RULAND MANUFACTURING DCD50-1-1/4"-25MM-A disc coupling?

This coupling has a 1 1/4 in x 25 mm bore diameter, 3 1/8 in OD, and a round clamp-on design. It features an aluminum hub and center spacer with stainless steel discs. The inch-to-metric bore accommodates different bore dimensions, and it includes two discs with a center spacer.

Where to buy the RULAND MANUFACTURING DCD50-1-1/4"-25MM-A disc coupling worldwide?

3G Electric supplies the RULAND MANUFACTURING DCD50-1-1/4"-25MM-A disc coupling worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select the correct RULAND MANUFACTURING disc coupling for inch-to-metric shafts?

Measure both shaft diameters and ensure the coupling's bore sizes match. For the DCD50-1-1/4"-25MM-A, one bore is 1 1/4 in and the other is 25 mm. Verify the OD (3 1/8 in) fits your space, and choose a clamp-on style for secure attachment without keyways.
