Product Description

Frequently Asked Questions

What is a RULAND MANUFACTURING Slit Coupling used for?

A RULAND MANUFACTURING Slit Coupling, such as the MRLC20-8-4-A, is used to connect two shafts in motion-control systems while compensating for minor misalignment. It is common in precision automation, robotics, and servo-drive applications where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MRLC20-8-4-A Slit Coupling?

The RULAND MRLC20-8-4-A is a long clamp-on slit coupling with an 8 mm bore diameter on one side and a 4 mm bore diameter on the other. Its outside diameter is 20 mm. The manufacturer part number is MRLC20-8-4-A, and it is designed for zero-backlash torque transmission.

Where to buy RULAND MRLC20-8-4-A couplings worldwide?

You can source the RULAND MRLC20-8-4-A coupling 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 precision coupling.

How to install a RULAND clamp-on slit coupling?

To install a RULAND clamp-on slit coupling, first ensure both shaft ends are clean and free of burrs. Slide the coupling onto the shafts, align the bores, then tighten the clamp screws evenly to the manufacturer’s recommended torque. Avoid over-tightening to prevent distortion. Always check alignment after installation.

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.
