Frequently Asked Questions

What is a RULAND MANUFACTURING rigid coupling used for?

A RULAND MANUFACTURING rigid coupling connects two shafts in precise alignment for motion control, power transmission, and positioning applications. It is used in packaging, printing, robotics, and machine tools where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING MSPC-1-1/4"-30MM-SS rigid coupling?

This two-piece rigid coupling has a 1 1/4 in bore diameter on one side and a 30 mm bore diameter on the other, both round keyed. It is made by RULAND MANUFACTURING, part number MSPC-1-1/4"-30MM-SS, and is designed for stainless steel or similar applications.

Where to buy a RULAND MANUFACTURING rigid coupling worldwide?

3G Electric supplies RULAND MANUFACTURING rigid couplings worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on the MSPC-1-1/4"-30MM-SS or other bore combinations.

How to select the right RULAND MANUFACTURING rigid coupling for my application?

Select a rigid coupling by matching bore diameters to your shaft sizes and ensuring keyway type (round keyed here) aligns with your key stock. Consider shaft misalignment tolerance—rigid couplings require precise alignment. RULAND MANUFACTURING offers various bore combinations; verify torque and speed ratings for your load.

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.
