Rigid Shaft Coupling For Industrial Power

The Dayton 3ZN44 is a two-piece carbon steel coupling designed to connect two shafts in power transmission equipment. It suits maintenance teams and machinery builders who need a fixed, backlash-free joint for in-line shafts.

Clamp Style Allows Straightforward Shaft Alignment

The clamp design lets installers position each half on the shaft and tighten without disassembling adjacent components. A common issue is exceeding the 4,000 RPM limit or the 480 in-lb torque rating, which can cause premature wear or coupling failure.

Verify Shaft Diameters

Both bores are round at 1-1/2 in and 1-1/2 in, so each shaft must match that dimension exactly. Confirm the application runs below the maximum speed and torque figures, and ensure the 1.22 in clearance diameter fits within the available space.

Questions about this item

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

Verify smooth rotation up to 4,000 RPM without vibration and ensure transmitted torque stays within the 480 in-lb rating.

What components are included with the Dayton 3ZN44 coupling and what must be sourced separately?

The two-piece carbon steel coupling with 1.22 in clearance diameter is supplied; mounting hardware and shaft keys are not included.

Which Dayton 3ZN44 specification should I match to my application when selecting this coupling?

Choose based on the 1-1/2 in and 2-1/2 in round bore diameters, 1-1/8 in outside diameter, and 480 in-lb torque capacity.
