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 across industrial automation, machining, and packaging applications.

What are the specifications of the Ruland MRLS25-12-8-A slit coupling?

The Ruland MRLS25-12-8-A is a long set screw slit coupling with a 12 mm bore diameter 1, an 8 mm bore diameter 2, and a 25 mm coupling outside diameter. It is designed for zero-backlash torque transmission and accommodates parallel, angular, and axial misalignment.

Where to buy Ruland Manufacturing couplings in worldwide?

3G Electric supplies Ruland Manufacturing couplings worldwide, handling full logistics, customs clearance, and delivery to your site. As a global industrial solutions provider, we source genuine Ruland components like the MRLS25-12-8-A and support procurement across 14 industrial departments.

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

To select the correct Ruland slit coupling, match bore diameters to your shaft sizes, verify the outside diameter fits your space, and confirm torque and misalignment ratings meet your system demands. For the MRLS25-12-8-A, ensure one shaft is 12 mm and the other is 8 mm.
