What this coupling does

The Dayton 2X497 is a flexible shaft coupling built to connect two round shafts with a 1 1/2 inch bore. It handles both angular and parallel misalignment using a rubber center element between steel hubs, and it secures with two set screws. The coupling is rated for 0.5 hp at 725 RPM and measures 2 1/2 inches overall length.

Who it suits and who it does not

Maintenance teams and OEMs needing to join shafts that cannot be perfectly aligned will find the 7 degree angular and 0.125 inch parallel capacity useful. It is not for applications that exceed the 0.5 hp rating or require speeds above 725 RPM. Buyers needing a different bore size, a clamp-style hub or a higher torque capacity should look elsewhere.

Behaviour under sustained load

The rubber element absorbs vibration and accommodates continuous misalignment without binding, letting the steel hubs transmit torque smoothly at the rated speed. Heat build-up stays low at 725 RPM, so the coupling maintains its 0.5 hp capacity during extended duty cycles. Regular inspection of the set screws and rubber condition keeps alignment stable over time.

Questions about this item

What shaft diameter must I already have for the 1 1/2 in bore to fit?

The coupling accepts a 1 1/2 in round shaft on each end, so both connected shafts must match that diameter.

Will the 725 RPM limit and .5 hp rating handle the older motor I plan to keep?

The coupling is rated for 725 RPM and .5 hp maximum; verify your motor stays at or below both figures.

How can I confirm the 7 degree angular and .125 in parallel misalignment are being absorbed after installation?

Run the system and check for smooth rotation without vibration, binding or excessive heat at the rubber center element.
