Dayton 2X498 Flexible Coupling Trap 1/2 in 0.5 hp 725 RPM
Connects shafts up to 0.5 hp at 725 RPM while handling 7° angular and 0.125 in parallel misalignment
- Product typeDrain Components
- Flexible Buna-N rubber sleeve absorbs vibration and misalignment
- Knurled steel hubs provide secure shaft grip with included set screws
- Handles angular misalignment up to 7 degrees for smooth power transfer
- Accommodates parallel offset of 0.125 in to reduce bearing stress
- Rated for 0.5 hp at 725 RPM for reliable light-duty operation
Application & User
The Dayton 2X498 is a flexible shaft coupling designed to connect two rotating shafts while absorbing angular and parallel misalignment. It suits maintenance teams and equipment builders who need a compact rubber-element coupling for light-duty power transmission.
Operational Limits
The coupling transmits up to .5 hp at 725 RPM and tolerates angular misalignment of 7 degrees with parallel offset of .125 in. Exceeding the speed or horsepower rating will accelerate wear on the Buna nitrate sleeve and reduce service life.
Installation Notes
Two set screws secure the knurled steel hubs onto 1 1/2 in round bores. The most common issue is insufficient hub engagement or over-tightening the screws, which can distort the rubber centre element and cause premature vibration.

Questions about this item
What does the 0.5 hp rating mean for everyday use?
The 0.5 hp maximum horsepower rating shows the power limit this coupling can transmit between shafts without overloading the rubber sleeve.
How does the 725 RPM limit affect installation choices?
The 725 RPM maximum speed caps the operating speed; the coupling must not be used on shafts rotating faster than this value.
What does the 0.125 in parallel misalignment figure allow in practice?
The 0.125 in parallel offset capacity lets the coupling absorb lateral shaft displacement while maintaining drive through the flexible rubber element.
