Product Description

The RULAND MANUFACTURING MRSS8-4-4-A is a short set screw slit coupling with 4 mm bore diameters on both ends and an 8 mm outside diameter. This coupling is designed for motion control applications requiring zero backlash and high torsional stiffness.

Frequently Asked Questions

What is a Ruland Manufacturing slit coupling used for?

A Ruland Manufacturing slit coupling connects two shafts in motion-control applications, compensating for minor misalignment while transmitting torque. It is commonly used in encoders, stepper motors, and precision positioning systems where zero backlash and high torsional stiffness are required.

What are the specifications of the Ruland MRSS8-4-4-A slit coupling?

The Ruland MRSS8-4-4-A is a short set screw slit coupling with 4 mm bore diameters on both ends and an 8 mm outside diameter. It is designed for compact installations and provides reliable torque transmission with minimal windup.

Where to buy a Ruland MRSS8-4-4-A coupling worldwide?

3G Electric supplies and delivers the Ruland MRSS8-4-4-A slit coupling worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to ensure the coupling reaches your facility, regardless of location.

How to install a Ruland set screw slit coupling?

To install a Ruland set screw slit coupling, align the two shafts within the specified misalignment limits, slide the coupling onto both shaft ends, and tighten the set screws evenly using a hex key. Ensure the screws seat into the shaft flats or keyways for secure torque transmission.

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.
