Product Description

The RULAND MANUFACTURING Slit Coupling is a short clamp-on slit coupling with a 4 mm bore diameter 1 and a 1/8 in bore diameter 2, round type, and an overall length of 21/32 in (MPN RSC8-4MM-1/8"-A). This component is designed for precise shaft connections in industrial equipment.

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 where zero backlash and high torsional stiffness are required.

What are the specifications of the Ruland RSC8-4MM-1/8"-A slit coupling?

The Ruland RSC8-4MM-1/8"-A is a short clamp-on slit coupling with a 4 mm bore diameter on one side and a 1/8 in bore diameter on the other. Its overall length is 21/32 in, and it features a round outer diameter. This Ruland coupling is designed for precision motion control.

Where to buy Ruland Manufacturing couplings worldwide?

You can source Ruland Manufacturing couplings worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the RSC8-4MM-1/8"-A or other Ruland slit couplings.

How to select the correct Ruland slit coupling for an application?

To select the correct Ruland slit coupling, match the bore diameters to your shaft sizes (e.g., 4 mm and 1/8 in for the RSC8-4MM-1/8"-A), consider the overall length and torque requirements, and ensure the coupling type (clamp-on) fits your installation. Ruland couplings provide zero-backlash performance for precision systems.
