Frequently Asked Questions

What is the RULAND MANUFACTURING SPX-6-4-F rigid shaft coupling used for?

The RULAND MANUFACTURING SPX-6-4-F is a two-piece rigid shaft coupling used to connect two shafts with different bore diameters—3/8 in and 1/4 in—in industrial power transmission applications. It provides zero-backlash torque transfer and precise alignment in motion control, packaging, and automation equipment.

What are the specifications of the RULAND MANUFACTURING SPX-6-4-F?

The RULAND MANUFACTURING SPX-6-4-F is a two-piece rigid shaft coupling with a round design. It has a 3/8 in bore diameter on one end and a 1/4 in bore diameter on the other, accommodating different bore dimensions. It is an inch-series coupling supplied by RULAND MANUFACTURING.

Where to buy the RULAND MANUFACTURING SPX-6-4-F worldwide?

You can source the RULAND MANUFACTURING SPX-6-4-F rigid shaft coupling through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact 3G Electric for availability and lead time on this coupling.

How to select the right RULAND MANUFACTURING rigid shaft coupling?

To select the correct RULAND MANUFACTURING rigid shaft coupling, match the bore diameters to your shaft sizes—for the SPX-6-4-F, one end is 3/8 in and the other is 1/4 in. Ensure the coupling style (round, two-piece) fits your application. RULAND MANUFACTURING couplings provide precise alignment and zero backlash for motion control systems.
