Product Description

Frequently Asked Questions

What is the RULAND MANUFACTURING PSR20-4-4-SS coupling used for?

The RULAND MANUFACTURING PSR20-4-4-SS is a high-precision set screw beam shaft coupling used in motion control applications. It connects two shafts while accommodating up to 3° angular misalignment, making it ideal for precision positioning systems, encoders, and light-duty power transmission where accurate alignment is critical.

What are the specifications of the RULAND MANUFACTURING PSR20-4-4-SS?

The PSR20-4-4-SS has a 1/4 in bore diameter with same bore dimensions, a round body, and inch sizing. It is not keyed and accommodates up to 3° angular misalignment. This RULAND MANUFACTURING coupling is designed for high-precision motion control and is made of stainless steel for durability.

Where to buy the RULAND MANUFACTURING PSR20-4-4-SS worldwide?

You can source the RULAND MANUFACTURING PSR20-4-4-SS 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 this high-precision motion control coupling.

How to select the right RULAND MANUFACTURING beam coupling for misalignment?

To select the right RULAND MANUFACTURING beam coupling, first measure your shaft diameters and ensure they match the bore size, such as the 1/4 in bore on the PSR20-4-4-SS. Consider the angular misalignment your application requires—this model handles up to 3°. Also verify torque and speed requirements against the coupling's ratings.

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.
