Product Description

The RULAND MANUFACTURING Disc Coupling (MPN DCD50-1-1/4"-30MM-A) is a double disc coupling for round shafts with a 1 1/4 in x 30 mm bore diameter and 3 1/8 in OD. It features a clamp-on design with two discs and a center spacer, constructed from aluminum hubs and stainless steel discs. This coupling accommodates inch to metric bore dimensions with different bore dimensions.

Frequently Asked Questions

What is the RULAND MANUFACTURING DCD50-1-1/4"-30MM-A disc coupling used for?

This double disc coupling connects two rotating shafts while accommodating misalignment. It is commonly used in motion control, packaging, and automation equipment where precision torque transmission and zero backlash are required. The aluminum hubs and stainless steel discs provide high torsional stiffness and corrosion resistance.

What are the specifications of the RULAND MANUFACTURING DCD50-1-1/4"-30MM-A disc coupling?

This coupling has a 1 1/4 in x 30 mm bore diameter, 3 1/8 in OD, and a round clamp-on design. It features two discs with a center spacer, aluminum hubs, and stainless steel discs. It accommodates inch to metric bore dimensions with different bore sizes. The manufacturer part number is DCD50-1-1/4"-30MM-A.

Where to buy the RULAND MANUFACTURING DCD50-1-1/4"-30MM-A disc coupling worldwide?
