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 torque transmission are required. The SPC-6-4-F model has a 3/8 in and 1/4 in bore with a round keyway for inch shafts.

What are the specifications of the RULAND MANUFACTURING SPC-6-4-F rigid shaft coupling?

The RULAND MANUFACTURING SPC-6-4-F is a two-piece rigid shaft coupling with bore diameters of 3/8 in and 1/4 in. It features a round keyed design for inch shafts. The manufacturer part number is SPC-6-4-F. It is made by RULAND MANUFACTURING and is suitable for precise shaft alignment in industrial machinery.

Where to buy RULAND MANUFACTURING rigid shaft couplings worldwide?

You can source RULAND MANUFACTURING rigid shaft couplings like the SPC-6-4-F from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead times on this and other RULAND MANUFACTURING components.

How to select a RULAND MANUFACTURING rigid shaft coupling for an application?

To select a RULAND MANUFACTURING rigid shaft coupling, match bore diameters to your shaft sizes and choose between keyed or keyless designs. The SPC-6-4-F is for inch shafts with a round keyway. Ensure shafts are aligned within 0.002 in to avoid binding. RULAND MANUFACTURING couplings provide zero backlash for precision motion control systems.
