Browning VF2S-216 AH Air Handling 2-Bolt Flange Ball Bearing Unit, 1" Bore, Cast Iron, Setscrew Lock

The Browning VF2S-216 AH is a normal-duty, air handling 2-bolt flange mounted ball bearing unit designed for shaft support in fans, blowers, and HVAC air handling equipment. The "AH" (Air Handling) designation indicates a looser-than-standard housing fit for ease of alignment on lightweight frames, along with a noise-tested, low-vibration design suited for quiet operation environments.

The unit features a powder coat epoxy cast iron housing for rigidity and vibration damping, housing a deep-groove radial ball bearing insert made from 52100 chromium steel with a black oxide coated inner ring. A rivet on the outer ring prevents rotation within the housing, reducing heat buildup and extending bearing service life. The self-aligning insert has a convex sphered outer surface to compensate for shaft misalignment.
