Overview
The Rexnord PEB22439H is a Link-Belt B22400 Series solid-housed pillow block spherical roller bearing engineered for demanding industrial motion and power transmission applications. This 2-7/16″ bore unit combines proven spherical roller technology with a rugged cast iron pillow block housing, delivering reliable performance in mining, manufacturing, cement, and paper production environments.
Key Features
- Self-aligning double-row spherical roller design for balanced load distribution and smooth operation
- Expansion cast iron 2-bolt pillow block housing accommodates thermal expansion
- Single setscrew locking collar ensures secure shaft attachment
- Clearance seal provides protection against contaminants
- High radial and combined radial-thrust load capacity with osculation clearance to prevent edge loading
- Double contoured retainer pockets engineered for shock load compensation
