Frequently Asked Questions

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

The RULAND MANUFACTURING SPX-6-4-SS is a two-piece rigid shaft coupling used to connect two shafts with different bore diameters—3/8 in and 1/4 in—in applications requiring precise alignment and torque transmission. It is commonly used in industrial machinery, conveyors, and motion control systems where zero backlash and high torsional stiffness are needed.

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

The RULAND MANUFACTURING SPX-6-4-SS is a two-piece rigid shaft coupling with a round shape and inch dimensions. It has a bore diameter 1 of 3/8 in and a bore diameter 2 of 1/4 in, accommodating different bore dimensions. The manufacturer part number is SPX-6-4-SS, and it is designed for secure, backlash-free shaft connections.

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

You can source the RULAND MANUFACTURING SPX-6-4-SS rigid shaft coupling worldwide through 3G Electric. As a global industrial equipment distributor since 1990, 3G Electric handles full logistics, customs clearance, and delivery to your location.

How to select the correct RULAND MANUFACTURING rigid shaft coupling?

To select the correct RULAND MANUFACTURING rigid shaft coupling like the SPX-6-4-SS, match the bore diameters to your shaft sizes—here 3/8 in and 1/4 in—and ensure the coupling style (round, two-piece) fits your application. Verify inch dimensions and that the coupling accommodates different bore dimensions if needed. Consult RULAND MANUFACTURING's technical data for torque and misalignment limits.
