Overview
The Dodge 124209 (model F4B-SC-108) is a normal duty, non-expansion, single-lip flange-mount ball bearing unit widely used in machinery, conveyor systems, and industrial drive applications. This bearing features a 1-1/2 inch bore diameter and a cast iron housing with four mounting bolt holes, providing robust mechanical support and straightforward installation.
Key Features
- Superior locking force: Dodge uses 65º setscrew spacing for optimum balance between locking force and inner ring stress
- Reinforced cage design: SC-series ball cage made of heat-stabilized nylon with fiberglass reinforcement for durability and flexibility
- Anti-rotation pin: Simplified anti-rotation device prevents outer race rotation within the housing
- Patented DualGuard seal: Advanced sealing system provides maximum protection in tough, contaminated environments
- Cast iron housing: Durable, powder-coated construction suitable for standard industrial duty applications
