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, such as conveyors, packaging machinery, and industrial automation. It provides zero-backlash torque transmission and maintains exact shaft alignment, making it suitable for positioning systems where misalignment is not tolerated.

What are the specifications of the RULAND SCC-20-20-SS rigid shaft coupling?

The RULAND SCC-20-20-SS is a set screw rigid shaft coupling with a 1 1/4 in bore diameter on both ends, round keyed, and made by RULAND MANUFACTURING. It is designed for high-torque, zero-backlash connections between equal-diameter shafts in industrial equipment.

Where to buy RULAND MANUFACTURING rigid shaft couplings worldwide?

You can source RULAND MANUFACTURING rigid shaft couplings worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead times on the SCC-20-20-SS and other RULAND coupling models.

How to select a RULAND rigid shaft coupling for an application?

To select a RULAND rigid shaft coupling, match the bore diameter to your shaft sizes and confirm the keyway type (e.g., round keyed). Ensure the coupling material (stainless steel in the SCC-20-20-SS) suits your environment. Verify torque and speed ratings from RULAND's catalog, and account for zero-backlash requirements in precision drives.

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.
