Rigid Steel Coupling for 1/2 in Shafts

This stainless steel rigid coupling joins two 1/2 inch diameter shafts in industrial and automotive driveline applications. The one-piece clamp design provides a positive mechanical lock without a keyway, simplifying alignment on precision equipment. It is built for new installations where zero backlash and high torque transmission are required.

Simple Clamp Installation Avoids Keyway Work

The coupling installs by tightening two #8-32 socket head screws against the shaft surfaces, eliminating the need for keyway machining or set-screw dimpling. Over-tightening the screws beyond the rated torque can distort the bore and reduce holding power, so a calibrated torque wrench is recommended. Ensure both shafts are clean, free of burrs and within the 1/2 inch tolerance before clamping.

Rated for 280 in-lb at 4,000 RPM Continuous Duty

Under sustained load the coupling transmits up to 280 in-lb of torque at speeds up to 4,000 RPM without measurable wind-up or heat buildup. The solid stainless steel construction resists corrosion and maintains concentricity during extended operation. It is not suited for applications that require angular misalignment compensation or vibration damping.

Questions about this item

How do I confirm the ISCC-050-050-S coupling is operating correctly after installation?

Verify smooth rotation up to 4,000 RPM without vibration and ensure transmitted torque stays below the 280 in-lb limit during normal operation.

What comes with the ISCC-050-050-S coupling and what must I source separately?

The package includes one stainless-steel rigid clamp coupling with #8-32 screws; shafts matching the 1/2 in bore and any additional fasteners are not supplied.

Which version of the ISCC-050-050-S should I select for my application?

Choose this model when you need a 1/2 in bore, 1.375 in outside diameter, plain-finish stainless coupling rated for 280 in-lb torque and 4,000 RPM maximum speed.
