4 Bolt Flange Bearing

The Dayton 1F548 is a square housing flange bearing with a 3/4 in cylindrical bore designed for radial ball applications. It mounts via four bolt holes on a 2 1/2 in center-to-center pattern and arrives in new condition.

Speed and Temperature Headroom

The bearing operates from -30 to 200 degrees F and is rated for a maximum speed of 4,500 RPM. Double sealed construction with NLGI #2 equivalent lubricant protects the alloy steel insert inside the zinc die cast housing.

Fixed Expansion Type

This unit is a fixed expansion type bearing, meaning it locates the shaft axially without allowing for thermal growth. Buyers needing a floating or expansion bearing to accommodate shaft length changes should select a different design.

Highlights

  • Double-sealed closure keeps contaminants out for longer bearing life
  • Radial ball design handles combined radial and thrust loads in one unit
  • Zinc die-cast housing resists corrosion in harsh industrial environments
  • Fixed expansion type maintains precise shaft alignment under load

Questions about this item

Will the 3/4 in bore fit the shaft I already have?

The bearing has a cylindrical 3/4 in bore, so it will fit any shaft of that exact diameter.

How can I confirm the double-sealed radial ball bearing is running correctly after installation?

Listen for smooth, quiet rotation and check that the housing temperature stays well below the 200 Degrees F maximum during operation.

Does the zinc die-cast square housing include mounting bolts or do I need to supply them?

The unit comes as the bearing insert in its square housing only; mounting bolts are not included and must be purchased separately.
