Overview
The Dodge F4B-SC-108 pillow block bearing is a standard-duty, flange-mounted ball bearing unit designed for general-purpose industrial applications. With a 1-1/2″ bore diameter and 4-bolt square flange housing, this bearing provides robust support for rotating shafts in conveyors, pumps, fans, and other rotating machinery. The unit features Dodge’s proven set-screw locking mechanism and cast iron construction for durability and long service life.
Key Features
- Set-Screw Locking: Dodge uses 65° spacing for setscrews, offering optimum balance between locking force and inner ring stress
- Reinforced Ball Cage: Heat-stabilized nylon with fiber-glass reinforcement for added strength and flexibility
- Anti-Rotation Pin: Prevents rotation of the outer race within the housing for stable operation
- DualGuard Seal System: Patented sealing design that provides maximum protection in tough industrial environments
- Cast Iron Housing: Provides excellent corrosion resistance and structural integrity
- Relubricatable Design: Allows for regular greasing to extend bearing life
