Product Description

The RULAND MANUFACTURING Rigid Shaft Coupling is a two-piece rigid shaft coupling with a 1/2 in bore diameter 1 and 1/2 in bore diameter 2, round keyed, inch type (MPN SPC-8-8-SS). It is designed for precise shaft alignment and torque transmission in industrial applications.

Frequently Asked Questions

What is a RULAND MANUFACTURING rigid shaft coupling used for?

A RULAND MANUFACTURING rigid shaft coupling connects two shafts in precise alignment for motion control applications. It is commonly used in packaging, printing, and automation equipment where zero backlash and high torsional stiffness are required. The SPC-8-8-SS model features a two-piece design with 1/2 inch bore diameters and a round keyway.

What are the specifications of the RULAND SPC-8-8-SS rigid shaft coupling?

The RULAND SPC-8-8-SS is a two-piece rigid shaft coupling with 1/2 inch bore diameters on both ends. It has a round keyway and is made of stainless steel. The manufacturer part number is SPC-8-8-SS. This inch-series coupling is designed for precise shaft alignment in industrial machinery.

Where to buy RULAND rigid shaft couplings worldwide?

You can source RULAND rigid shaft couplings like the SPC-8-8-SS through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this and other RULAND coupling models.

How to select a rigid shaft coupling for a motion control system?

Select a rigid shaft coupling by matching bore diameters to your shaft sizes and ensuring the keyway type (e.g., round keyed) fits your key. Consider material—stainless steel like the RULAND SPC-8-8-SS offers corrosion resistance. For precise alignment, rigid couplings are ideal when shafts are already aligned and no misalignment compensation is needed.

Used in

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.
