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 low inertia are critical.

What are the specifications of the Ruland RSS8-1/4"-3MM-A slit coupling?

The Ruland RSS8-1/4"-3MM-A is a short set screw slit coupling with a 1/4 in bore diameter on one side and a 3 mm bore diameter on the other. Overall length is 21/32 in, and the outer diameter is round. It is made by Ruland Manufacturing.

Where to buy a Ruland Manufacturing slit coupling worldwide?

3G Electric supplies and delivers Ruland Manufacturing slit couplings worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to ensure your order reaches any international destination. Contact us for availability and lead time.

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

To select the correct Ruland slit coupling, match bore diameters to your shaft sizes (e.g., 1/4 in and 3 mm), confirm overall length fits your space, and verify torque and misalignment ratings from the manufacturer. For motion-control systems, choose zero-backlash designs like the RSS8 series.
