Overview
The Dodge 123817 pillow block bearing is a Series 209 normal-duty ball bearing unit designed for industrial machinery and power transmission applications. This 2-bolt mounted bearing features a 1-3/4 inch bore diameter, setscrew locking mechanism, and single-lip contact seal. The cast iron housing and powder-coated steel construction provide durability in demanding environments, making the Dodge 123817 an industry-standard drop-in replacement for mechanical drive systems.
Key Features
- Series 209 normal-duty ball bearing design rated for 7,891 lbs dynamic and 4,906 lbs static load
- Setscrew locking device ensures secure shaft retention without additional hardware
- Single-lip contact seal protects against contamination while minimizing friction loss
- Non-expansion (fixed) bearing type for rigid alignment in fixed-mounting applications
- Cast iron housing with powder-coated steel finish resists corrosion
- Two-bolt base mount with standard footprint for quick installation
- Operating temperature range 225°F to 400°F accommodates industrial process conditions
