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 low inertia are critical.

What are the specifications of the Ruland RLS8-3/16"-4MM-A slit coupling?

The Ruland RLS8-3/16"-4MM-A is a long set screw slit coupling with a 3/16 in bore diameter on one side and a 4 mm bore diameter on the other. Its overall length is 25/32 in, and it features a round body design for balanced high-speed operation.

Where to buy a Ruland Manufacturing slit coupling worldwide?

3G Electric supplies and delivers genuine Ruland Manufacturing slit couplings worldwide. As a global industrial sourcing partner, we handle full logistics and customs clearance to ensure your order arrives at your facility, regardless of location.

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

To select the correct Ruland slit coupling, match the bore diameters to your shaft sizes (e.g., 3/16 in and 4 mm), verify the overall length fits your space, and confirm torque and misalignment ratings meet your system requirements. Consult Ruland's technical data for specific performance limits.
