Double Sealed Cartridge Bearing

The Dayton 3FDF1 is a radial ball cartridge bearing unit built for inch-series shafts. Its 1 in bore and 2 17/32 in outside diameter suit HVAC and general machinery applications where a self-contained, double sealed unit simplifies installation and reduces maintenance intervals.

Upgrade from open or single sealed units

When an existing bearing runs unsealed or with a single seal, contaminants and moisture shorten service life. The double contact seal on this unit retains the NLGI #2 equivalent grease and excludes debris, making the switch worthwhile in dusty or humid environments where relubrication is difficult or infrequent.

Fits inch shafting with eccentric collar lock

The eccentric collar locks onto a 1 in shaft without a keyway, while the rubber housing cushions vibration and accommodates slight misalignment. Operating range spans -20 to 220 degrees F, and the 1.406 in overall width fits standard pillow block or flange housings, freeing the designer from specifying separate seals or bearing inserts.

Questions about this item

What shaft diameter fits the 1 in bore on this cartridge bearing?

The bearing accepts a 1 in shaft and locks with an eccentric collar that tightens against the shaft.

How do I install the eccentric collar without damaging the 52100 alloy steel insert?

Slide the unit onto the shaft, then turn the collar in the direction of rotation until it seats, and tighten the set screw to lock it.

When should I replace the NLGI #2 equivalent grease inside the double sealed unit?

The bearing is lubricated for life; replace the entire unit if noise, heat or vibration appear beyond the -20 to 220 Degrees F range.
