Product Description

Frequently Asked Questions

What is the RULAND MANUFACTURING SPX-18-18-F rigid shaft coupling used for?

The RULAND MANUFACTURING SPX-18-18-F is a two-piece rigid shaft coupling used to connect two shafts of equal diameter (1 1/8 in) in applications requiring zero backlash and precise alignment. It is common in motion control, packaging, and conveyor systems where a solid, maintenance-free connection is needed.

What are the specifications of the RULAND MANUFACTURING SPX-18-18-F?

The SPX-18-18-F has a 1 1/8 in bore diameter on both ends (same bore dimensions), a round clamp-on design, and is sized in inches. It is a two-piece rigid coupling from RULAND MANUFACTURING, with part number SPX-18-18-F. It does not include a keyway.

Where to buy the RULAND MANUFACTURING SPX-18-18-F worldwide?

3G Electric supplies the RULAND MANUFACTURING SPX-18-18-F rigid shaft coupling to customers worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to deliver this coupling to your facility. Contact us for pricing and lead time.

How to install a RULAND MANUFACTURING clamp-on rigid shaft coupling?

To install the SPX-18-18-F, clean both shaft ends and the coupling bore. Loosen the clamp screws, slide the coupling onto the shafts, align the shafts, then tighten the screws evenly to the manufacturer's torque specification. Ensure shafts are aligned within 0.002 in for optimal performance.
