Frequently Asked Questions

What is a Ruland Manufacturing slit coupling used for?

A Ruland Manufacturing slit coupling connects two shafts in motion-control systems, compensating for minor misalignment while transmitting torque. It is commonly used in encoders, stepper motors, and precision positioning equipment across industrial automation, packaging, and robotics applications.

What are the specifications of the Ruland RSS8-4MM-1/8"-A slit coupling?

The Ruland RSS8-4MM-1/8"-A is a short set screw slit coupling with a 4 mm bore diameter on one side and a 1/8 in bore diameter on the other. Overall length is 21/32 in, and the body shape is round. It is made by Ruland Manufacturing.

Where to buy Ruland Manufacturing slit couplings worldwide?

3G Electric supplies Ruland Manufacturing slit couplings worldwide. As a global industrial sourcing partner, we handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on the RSS8-4MM-1/8"-A or other Ruland couplings.

How to select the right Ruland slit coupling for a shaft misalignment?

To select a Ruland slit coupling, measure both shaft diameters and the gap between shaft ends. Choose a coupling with bore sizes matching each shaft and an overall length that fits your space. Ruland couplings accommodate parallel, angular, and axial misalignment; consult the manufacturer's torque and misalignment ratings for your application.

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.
