Frequently Asked Questions

What is a RULAND MANUFACTURING disc coupling used for?

A RULAND MANUFACTURING disc coupling connects two round shafts in motion-control systems, compensating for misalignment while transmitting torque. It is commonly used in servo motors, encoders, and precision positioning equipment where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND DCD50-28-28-A disc coupling?

The RULAND DCD50-28-28-A is a double disc coupling with a 1 3/4 in bore diameter, 3 1/8 in OD, and clamp-on round design. It has an aluminum hub and center spacer with stainless steel discs, rated for inch-size shafts with same bore dimensions.

Where to buy a RULAND disc coupling worldwide?

3G Electric supplies the RULAND DCD50-28-28-A disc coupling to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact our team for a quote and lead time on this precision coupling.

How to install a RULAND clamp-on disc coupling?

To install a RULAND clamp-on disc coupling, clean both shaft ends and the bore. Loosen the clamp screws, slide the coupling onto the shafts, align the equipment, then tighten the screws evenly to the manufacturer's torque specification. Avoid over-tightening to prevent disc damage.
