Link-Belt P3-U233H Pillow Block Ball Bearing 2-1/16 in Bore 2-Bolt P3U233H

The Link-Belt P3-U233H (P3U233H) is a 200 Series standard-duty two-bolt pillow block ball bearing unit from Rexnord’s Link-Belt Bearing Division, today part of Regal Rexnord. It mounts a 2-1/16 in (52.39 mm) bore, wide inner race ball bearing insert in a one-piece solid cast iron housing with setscrew shaft locking in a non-expansion (fixed) configuration. The H suffix denotes Link-Belt’s clearance-type labyrinth seal, which runs cooler and supports higher shaft speeds than lip-contact seals, and the unit is relubricatable through a standard grease fitting.

Link Belt H-series pillow blocks are widely specified on fans, blowers, air handlers, conveyors, aggregate equipment, and general mechanical power transmission drives. Rexnord has discontinued factory production of this part number, so new old stock is the direct way to replace a worn P3-U233H in place – same mounting footprint, no re-engineering. The replacement insert for this housing series is UG233HL (verify against the insert number stamped on your unit). Envelope-comparable to other 2-1/16 in two-bolt cast iron pillow block units (UCP211-33 style); verify shaft height, bolt centers, and seal type before substituting. Also written P3-U233H, P3 U233H, or P3U233H.
