Worm hangers, also called hanger bearings, are critical support components used in screw conveyors and auger systems. They are installed between screw sections to support the rotating shaft and prevent it from sagging or contacting the conveyor casing.
These bearings act as plain (journal) bearings, allowing smooth rotation while reducing friction and wear. They are especially important in long conveyor systems where multiple screw sections are connected.
Common types include:
- 216 Type – heavy-duty, double support
- 226 Type – lighter, less obstruction to material flow
Worm hangers are manufactured using materials like:
- Mild steel (general use)
- Carbon steel (heavy-duty)
- Bronze / nylon (low friction applications)
