Overview
The Rexnord FEB22431H is a Link-Belt B22400 series flanged block spherical roller bearing designed for general industrial duty. Features a 1-15/16″ (49.2 mm) bore with 4-bolt round flange mounting for secure, vibration-free installation on vertical or horizontal shafts. The expansion (floating) design accommodates thermal growth and shaft misalignment.
Key Features
- Spherical roller design: Self-aligning double-row construction distributes radial and combined radial-thrust loads uniformly across roller complement
- Expansion bearing: Floating design allows axial shaft movement, ideal for belt or chain drive applications
- Cast iron housing: Corrosion-resistant, powder-coated finish; rated for standard duty
- Single setscrew collar locking: Simple, secure collar prevents bearing rotation on shaft
- Labyrinth seal: Clearance seal provides protection without excessive drag or heat buildup
- Grease lubrication: 1/8 NPT grease fitting for periodic maintenance
