Overview
The Rexnord PB22431H is a Link-Belt B22400 series solid-housed pillowblock bearing designed for industrial mechanical power transmission. This 1-15/16 inch mounted spherical roller bearing combines a cast iron housing with precision-engineered internal components, providing dependable alignment and load distribution across double-row spherical rollers. The solid-housed design eliminates split-housing maintenance concerns, making it ideal for fixed mounting applications in conveyors, crushers, fans, and pump drives.
Key Features
- Two-piece outer ring design reduces misalignment-induced bearing failure by providing double the static and dynamic misalignment capacity compared to standard bearings
- Cast iron solid housing rated for standard duty with a 2-1/2 inch base width and corrosion-resistant powder-coated finish
- Concentric setscrew locking collar enables secure, repeatable installation without additional fasteners
- Labyrinth clearance seal protects internal components while allowing field seal replacement if needed
- Industry-standard dimensions provide interchangeability with competing manufacturers and facilitate drop-in retrofits
