Overview
The UCF207-23 flange bearing is a heavy-duty 4-bolt square flange mounted ball bearing unit designed for industrial machinery and conveyor systems. Featuring a cast iron F207 housing and chrome steel UC207-23 bearing insert, this unit delivers reliable performance in demanding rotational applications. The self-aligning ball bearing design accommodates slight shaft misalignment, while the set-screw locking device prevents shaft slippage during operation.
Key Features
- 1-7/16″ (35 mm) bore diameter fits standard cylindrical shafts
- 4-bolt square flange mounting for secure attachment to perpendicular surfaces
- Cast iron housing provides structural rigidity and corrosion resistance
- Self-aligning chrome steel bearing insert with C3 internal clearance
- Set-screw locking mechanism eliminates shaft rotation
- Synthetic rubber seal protects against contamination across temperature extremes
- Relubricating design with grease zerk fitting for extended service life
