Product Description

The RULAND MANUFACTURING Disc Coupling (MPN DCD44-1-1/2"-30MM-A) is a double disc coupling for round shafts with a 1 1/2 in x 30 mm bore diameter and 2 3/4 in OD. It features a clamp-on design with two discs and a center spacer, constructed from aluminum hubs and stainless steel discs. This inch-to-metric bore coupling accommodates different bore dimensions and is designed for round shafts.

Frequently Asked Questions

What is the RULAND MANUFACTURING DCD44-1-1/2"-30MM-A disc coupling used for?

This double disc coupling connects round shafts with different bore dimensions (1 1/2 in and 30 mm) in motion-control applications. It compensates for misalignment while transmitting torque, making it suitable for precision drives, encoders, and servo systems where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING DCD44-1-1/2"-30MM-A disc coupling?

This coupling has a 1 1/2 in x 30 mm bore diameter, 2 3/4 in OD, and a round clamp-on design. It features aluminum hubs, stainless steel discs, and a center spacer with two discs. The inch-to-metric bore accommodates different shaft sizes. RULAND MANUFACTURING specifies this for round shafts.

Where to buy the RULAND MANUFACTURING DCD44-1-1/2"-30MM-A disc coupling worldwide?
