Product Description

The RULAND MANUFACTURING Two-Piece Rigid Shaft Coupling (MPN SPC-18-16-F) is a round keyed, inch-type coupling with a 1 1/8 in bore diameter on one side and a 1 in bore diameter on the other. This rigid coupling provides a fixed, zero-backlash connection for precise shaft alignment in industrial power transmission applications.

Frequently Asked Questions

What is a Ruland rigid shaft coupling used for?

A Ruland rigid shaft coupling connects two shafts in precise alignment for motion control applications. It is used in packaging, printing, and conveyor systems where zero backlash and high torque transmission are required. The SPC-18-16-F model has a 1 1/8 in bore and a 1 in bore, both round keyed.

What are the specifications of the Ruland SPC-18-16-F coupling?

The Ruland SPC-18-16-F is a two-piece rigid shaft coupling with bore diameters of 1 1/8 in and 1 in. It is round keyed, inch-sized, and made by Ruland Manufacturing. This coupling provides a zero-backlash, high-torque connection for shafts requiring precise alignment.

Where to buy Ruland rigid shaft couplings worldwide?

3G Electric supplies Ruland rigid shaft couplings like the SPC-18-16-F to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this and other Ruland motion control components.

How to select a rigid shaft coupling for an application?

Select a rigid shaft coupling by matching bore diameters to your shaft sizes and ensuring keyway type (square or round) aligns with your key. Consider torque requirements and shaft misalignment tolerance. For precise alignment applications, Ruland couplings like the SPC-18-16-F provide zero-backlash performance.
