Frequently Asked Questions

What is a RULAND MANUFACTURING rigid shaft coupling used for?

A RULAND MANUFACTURING rigid shaft coupling connects two shafts in precise alignment for motion control applications. It is used in packaging, printing, and automation equipment where zero backlash and torsional rigidity are required. The SCC-18-18-SS model has a 1 1/8 in bore diameter and is made of stainless steel.

What are the specifications of the RULAND SCC-18-18-SS rigid shaft coupling?

The RULAND SCC-18-18-SS is a set screw rigid shaft coupling with a 1 1/8 in bore diameter on both ends. It features a round keyed design and is made of stainless steel. The manufacturer part number is SCC-18-18-SS, and it is designed for high-torque, precision alignment applications.

Where to buy RULAND rigid shaft couplings worldwide?

You can source RULAND rigid shaft 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 SCC-18-18-SS or other RULAND coupling models.

How to select the right RULAND rigid shaft coupling for an application?

Select a RULAND rigid shaft coupling by matching bore diameters to your shaft sizes and ensuring the coupling material suits the environment. For the SCC-18-18-SS, both bores are 1 1/8 in with a round keyway. Consider torque requirements and shaft misalignment tolerance; rigid couplings provide zero backlash but require precise alignment.
