Overview
The Rexnord PEB22439H is a solid-housed pillow block spherical roller bearing from the Link-Belt B22400 series. This unit combines 2-7/16″ bore diameter with expansion-type cast iron housing, delivering proven durability for demanding industrial applications. Self-aligning double row spherical roller bearings are designed to distribute the load over the symmetrical rollers, assuring positive tracking and smooth operation, with the large roller complement providing high capacity for radial or combined radial-thrust loads. The solid-housed pillow block features a 2-7/16″ mounted spherical roller bearing within an expansion cast iron 2-bolt pillow block, employing a single setscrew locking collar for secure attachment and includes a clearance seal.
Key Features
- Spherical roller design: Osculation clearance at the ends of the rollers compensates for shock loads and prevents destructive edge loading.
- 2-bolt base mounting: Expansion type for shaft accommodation and thermal growth
- Single setscrew locking collar: Secure, easy-to-adjust shaft retention
- Clearance/floating labyrinth seal: Protects against contaminants while minimizing friction
- Cast iron housing: Durable construction rated to 225°F continuous operation
- Self-aligning capability: Compensates for minor shaft deflection and installation misalignment

Typical Applications
This bearing unit is commonly used in conveying systems for head, tail, and tensioning station roller shaft supports for belt conveyors, chain conveyors, and screw conveyors, as well as lifting equipment supports for bucket elevators and winches, and mining and metallurgical equipment such as vibrating screens, crushers, and mineral processing equipment. The bearing is commonly used at the output shaft end of gearboxes as a support point for the extended shaft, and supports fan or pump shafts, especially when the motor is directly connected via a coupling. Heavy-load applications in textile mills, paper production, cement manufacturing, and general industrial machinery also benefit from the PEB22439H’s load capacity and self-aligning design.
