Overview
The Dodge F4R-S2-207R bearing (part number 070446) is a non-expansion, 4-bolt flange-mount spherical roller bearing unit designed for heavy-duty industrial applications. This bearing features a 2-7/16″ bore diameter with a cast iron housing and round flange mounting configuration, making it a reliable drop-in replacement for many machinery and power transmission systems.
Key Features
- Spherical Roller Design: Accommodates shaft misalignment up to 1.5°, reducing stress on machinery and extending service life
- 4-Bolt Round Flange Mount: Secure, symmetrical mounting with 6.75″ bolt circle diameter and 4.766″ bolt center-to-center spacing
- Set Screw Locking Device: 65° locking mechanism ensures the bearing stays fixed during operation and prevents slippage
- Triple-Lip Contact Seal: Advanced sealing with Trident triple-lip design protects against contamination and extends bearing life
- Grease-Lubricated: Pre-filled with MobilGrease XHP222 for consistent performance; ideal for minimal-maintenance applications
- Non-Expansion (Fixed) Bearing: Rigid design suitable for applications requiring precision shaft positioning
