RULAND MANUFACTURING Slit Coupling: 4 mm Bore Dia 1, 1/8 in Bore Dia 2, 21/32 in Overall Lg

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, packaging, and robotics applications.

The Ruland RSS8-4MM-1/8"-A is a short set screw slit coupling with a 4 mm bore diameter on one side and a 1/8 in bore diameter on the other. Overall length is 21/32 in, and the body shape is round. It is made by Ruland Manufacturing.

To select a Ruland slit coupling, measure both shaft diameters and the gap between shaft ends. Choose a coupling with bore sizes matching each shaft and an overall length that fits your space. Ruland couplings accommodate parallel, angular, and axial misalignment; consult the manufacturer's torque and misalignment ratings for your application.
