Bearing Unit for HVAC Systems

The Dayton 3FDE9 is a double sealed cartridge bearing unit designed for HVAC applications. It features a 3/4 in bore diameter and a 2 17/32 in outside diameter to fit standard shaft sizes. The unit uses a radial ball insert made from 52100 alloy steel for reliable rotation.

Rubber Housing with Eccentric Collar Lock

A rubber housing provides vibration damping and corrosion resistance in mounting configurations. The eccentric collar shaft locking type secures the inner ring to the shaft with a simple turn and set screw action. Double contact seals retain the NLGI #2 equivalent lubricant while blocking contaminants.

Temperature Range Defines Operating Limits

Continuous operation is rated between -20 degrees F and 220 degrees F. Exceeding the maximum temperature can degrade the lubricant and seal materials, reducing service life. The single row of rolling elements suits moderate radial loads but is not intended for heavy axial thrust.
