Product Description

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 RSC8-4-2-A slit coupling?

The Ruland RSC8-4-2-A is a short clamp-on slit coupling with a 1/4 in bore diameter 1 and a 1/8 in bore diameter 2. Its overall length is 21/32 in. This inch-series coupling is designed for zero-backlash torque transmission in light-duty servo and encoder applications.

Where to buy Ruland Manufacturing couplings worldwide?

3G Electric supplies Ruland Manufacturing couplings like the RSC8-4-2-A to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for a quote on this or any other motion-control component across our 14 industrial departments.

How to select the correct Ruland slit coupling for a shaft?

To select the correct Ruland slit coupling, match both bore diameters to your shaft sizes and confirm the overall length fits your space. Consider torque requirements and misalignment tolerance. For the RSC8-4-2-A, bores are 1/4 in and 1/8 in with a 21/32 in length.

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.
