Product Description

The RULAND MANUFACTURING Two-Piece Rigid Shaft Coupling (SKU SPC-28-28-F, MPN SPC-28-28-F) is a round keyed coupling with a 1 3/4 in bore diameter on both ends. It is designed for precise shaft alignment and torque transmission in industrial 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, power transmission, and positioning applications. It is used in industrial machinery, packaging equipment, and conveyor systems where zero backlash and high torsional stiffness are required.

What are the specifications of the Ruland SPC-28-28-F coupling?

The Ruland SPC-28-28-F is a two-piece rigid shaft coupling with a 1 3/4 inch bore diameter on both ends, round keyed. It is manufactured by Ruland Manufacturing and is designed for heavy-duty torque transmission in industrial applications.

Where to buy Ruland rigid shaft couplings worldwide?

3G Electric supplies Ruland rigid shaft couplings worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on the SPC-28-28-F or other Ruland coupling sizes.

How to select the right rigid shaft coupling for an application?

Select a rigid shaft coupling by matching bore diameters to your shaft sizes, ensuring keyway dimensions align, and verifying torque capacity exceeds your system's peak load. For the Ruland SPC-28-28-F, confirm both shafts are 1 3/4 inch and round keyed. Consult a technical specialist for alignment and installation best practices.
