Frequently Asked Questions

What is the RULAND MANUFACTURING disc coupling used for?

The RULAND MANUFACTURING disc coupling is used to connect two shafts in power transmission applications, accommodating misalignment while transmitting torque. It is ideal for precision motion control, servo systems, and industrial machinery where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND disc coupling DCDK44-1-1/2"-30MM-A?

This double disc coupling has a 1 1/2 in x 30 mm bore diameter, 2 3/4 in OD, round with keyway bore, aluminum hub and center spacer, and stainless steel disc packs. It is designed for inch to metric bore applications with different bore dimensions and includes a center spacer.

Where to buy RULAND disc couplings worldwide?

You can source RULAND disc couplings worldwide through 3G Electric, 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 DCDK44-1-1/2"-30MM-A or other RULAND models.

How to select the right RULAND disc coupling for keyed shafts?

To select the right RULAND disc coupling, match the bore diameter and keyway dimensions to your shaft sizes. Consider torque requirements, misalignment tolerance, and operating speed. For inch-to-metric applications like the DCDK44-1-1/2"-30MM-A, verify both bore sizes and ensure the coupling type (double disc with spacer) fits your space constraints.
