Rigid Shaft Coupling

The Climax Metal Products ISCC-075-075 is a one-piece rigid shaft coupling designed for power transmission applications. It connects two shafts with matching 3/4 in round bores in a fixed alignment. This component suits maintenance engineers and machinery builders who need a simple, zero-backlash connection for light-duty drive lines.

Capacity and headroom

The coupling transmits up to 1,540 in-lb of torque and is rated for speeds up to 4,000 RPM. Within those limits it handles steady or reversing loads without introducing compliance. Applications that exceed the torque rating or require misalignment compensation will need a flexible or larger coupling instead.

Practical limits of the standard

The one-piece carbon steel construction demands precise shaft alignment and straight bores during installation. A clearance diameter of 1.81 in sets the minimum space needed around the hub. There is no keyway provision, so torque transfers purely by friction or set-screw engagement on the round shafts.

Questions about this item

Will the 1.81 in clearance diameter fit around the flanges on my existing 3/4 in shafts?

The coupling has a 1.81 in clearance diameter and a 3/4 in bore, so it will slide over standard 3/4 in shaft flanges without interference.

How can I confirm the coupling is seated correctly after installation?

After tightening the set screws, rotate the assembly by hand; it should turn smoothly up to the rated 4,000 RPM with no wobble or binding.

Does the box include set screws or keys, or must I order them separately?

The one-piece carbon-steel coupling is supplied complete; no separate keys or fasteners are required for the plain round bore.
