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 automation equipment where zero backlash and high torsional stiffness are required. 3G Electric supplies this coupling across 14 industrial departments.

What are the specifications of the Ruland SPC-6-6-SS coupling?

The Ruland SPC-6-6-SS is a two-piece rigid shaft coupling with 3/8 inch bore diameters on both ends, round keyed, inch series. It is made by Ruland Manufacturing and is suitable for applications requiring accurate shaft alignment and torque transmission.

Where to buy Ruland rigid shaft couplings worldwide?

3G Electric supplies Ruland rigid shaft couplings worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on the SPC-6-6-SS or other Ruland motion control components.

How to select a rigid shaft coupling for a keyed shaft?

Select a rigid coupling with bore diameters matching your shaft sizes and a keyway type that fits your key. For the Ruland SPC-6-6-SS, both bores are 3/8 inch with a round keyway. Ensure shaft alignment is precise, as rigid couplings do not compensate for misalignment.

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.
