Overview
The Link Belt PEB22439FH is a solid-housed pillow block bearing featuring a mounted spherical roller bearing mounted in expansion cast iron housing. This 2-7/16″ bore unit combines proven Rexnord engineering with industry-standard design for critical rotating shaft applications. The expansion housing accommodates shaft growth during thermal expansion while maintaining precise alignment.
Key Features
- Spherical Roller Design: Double-row spherical rollers self-align to distribute combined radial and thrust loads evenly, preventing edge loading and extending bearing life.
- Expansion Cast Iron Housing: Accommodates shaft thermal expansion and prevents binding during operation.
- Single Setscrew Locking Collar: Provides secure, concentric mounting without special tools; easily adjustable for different shaft sizes.
- Clearance Seal: Floating labyrinth design protects against contaminant entry while allowing normal lubrication flow.
- Relubricatable: Designed for on-condition maintenance with standard grease or oil lubrication at bearing relief points.
- Two-Bolt Base: Standard mounting footprint for quick installation and field replacement in existing installations.
