Product Description

The RULAND MANUFACTURING Disc Coupling (MPN DCD50-45MM-1-3/4"-A) is a double disc coupling for round shafts with a 45 mm x 1 3/4 in bore diameter and 3 1/8 in OD. It features a clamp-on design, aluminum hub and center spacer, stainless steel discs, and accommodates inch to metric bores with different bore dimensions.

Frequently Asked Questions

What is a RULAND MANUFACTURING disc coupling used for?

A RULAND MANUFACTURING disc coupling connects two rotating shafts while compensating for misalignment. It is used in motion control, packaging, and automation equipment where precision torque transmission and zero backlash are required. The double disc design with a center spacer handles parallel offset and angular misalignment.

What are the specifications of the RULAND DCD50-45MM-1-3/4"-A disc coupling?

This double disc coupling has a 45 mm x 1 3/4 in bore diameter, 3 1/8 in OD, and a round clamp-on design. The hub and center spacer are aluminum, the discs are stainless steel, and it accommodates inch to metric bores with different bore dimensions. It includes two discs with a center spacer.

Where to buy RULAND MANUFACTURING disc couplings worldwide?

3G Electric supplies RULAND MANUFACTURING disc couplings 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 on the DCD50-45MM-1-3/4"-A or other RULAND coupling models.

How to select a RULAND disc coupling for inch to metric bore shafts?

Select a RULAND disc coupling like the DCD50-45MM-1-3/4"-A when connecting an inch shaft to a metric shaft. Ensure the bore diameters match your shaft sizes (45 mm and 1 3/4 in). The clamp-on design provides secure grip without shaft damage. Verify torque and misalignment ratings from RULAND's technical data.
