Frequently Asked Questions

What is a RULAND MANUFACTURING rigid shaft coupling used for?

A RULAND MANUFACTURING rigid shaft coupling connects two shafts in precision motion-control applications. It is used in packaging, printing, and robotics where zero backlash and high torsional stiffness are required. The two-piece design allows for easy installation and alignment.

What are the specifications of the RULAND SPC-18-18-F rigid shaft coupling?

The RULAND SPC-18-18-F is a two-piece rigid shaft coupling with a 1 1/8 inch bore diameter on both ends. It features a round keyed bore design for secure torque transmission. The manufacturer part number is SPC-18-18-F, and it is made by RULAND MANUFACTURING.

Where to buy RULAND rigid shaft couplings worldwide?

You can source RULAND rigid shaft couplings worldwide through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the SPC-18-18-F model.

How to install a RULAND two-piece rigid shaft coupling?

To install a RULAND two-piece rigid shaft coupling, first clean both shaft ends and the coupling bores. Slide the coupling halves onto the shafts, align the keyways, and tighten the clamping screws evenly in a cross pattern. Ensure shafts are aligned within 0.002 inches to prevent premature wear.

Common applications for RULAND MANUFACTURING

Automated packaging machinery — Ruland beam couplings (e.g., PSR20-8-5-A) for connecting servo motors to conveyor drive shafts.

CNC machine tools — Ruland rigid couplings (e.g., CLX-4-4-A) for precise alignment of ball screw assemblies.

Robotic arm joints — Ruland Oldham coupling hubs (e.g., OSC16-6-A) for accommodating axial motion in end-effector drives.

Pump and compressor systems — Ruland stainless steel shaft collars (e.g., CL-3-ST) for securing impeller shafts.

Printing press rollers — Ruland clamp-on beam couplings (e.g., PCR18-8-8-A) for synchronizing roller rotation with minimal backlash.

Material handling conveyors — Ruland set screw couplings (e.g., PSMR29-7-7-A) for linking gearboxes to drive rollers.
