Overview
The Dodge 070280 P2B-S2-203R is a Type S-2000 pillow block roller bearing unit designed for demanding industrial machinery and power transmission applications. With a 2-3/16″ bore diameter, cast iron housing, and heavy-duty load capacity, this mounted bearing assembly delivers reliable performance in conveyors, pumps, motors, and rotating equipment requiring fixed mounting and precise shaft support.
Key Features
- Spherical roller bearing with 2-3/16″ bore diameter for load equalization
- Cast iron, black oxide-finished housing for corrosion resistance
- Springlok concentric collar locking device for secure shaft retention
- Trident triple-lip contact seal design for extended grease retention
- Two-bolt base mount with 2.63″ base width for standard industrial footprints
- Non-expansion (fixed) bearing type for fixed-position mounting
- Lubricated with MobilGrease XHP222 for optimal performance

Typical Applications
The Dodge 070280 is well-suited for:
- Conveyor systems and belt drives requiring mid-range shaft support
- Pump and motor coupling applications with moderate to heavy loads
- Industrial machinery requiring sealed, grease-lubricated bearing blocks
- Equipment operating in general industrial environments with standard temperature ranges
- Fixed-position mounting where shaft misalignment is minimal
Compatibility & Replacements
Compatible With
- Standard industrial shaft sizes up to 2-3/16″ diameter
- Two-bolt pillow block mounting applications using S-2000 frame size
- Machinery designed for fixed (non-expansion) bearing installations
- Grease-lubricated bearing systems operating at 1,950 rpm or below
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. Alternative equivalent models from other manufacturers (such as Rexnord ZA2203, ZEP2203, or MA2203 series) may exist for 2-3/16″ applications but direct replacement eligibility depends on specific mounting footprint and performance requirements.
Works With
- Industrial machinery using spherical roller bearing inserts
- Conveyor and power transmission systems requiring sealed, mounted bearing blocks
- Standard two-bolt base pillow block mounting footprints
- Equipment utilizing MobilGrease XHP222 or compatible lubricants
