- **Caution**: 

### Q: What is the primary function of a thrust ring/reaction structure in machinery?
**A**: The thrust ring/reaction structure transfers and distributes thrust forces while providing critical reaction support during lifting operations in main jacking systems, ensuring stable load distribution.

### Q: What materials are typically used in manufacturing thrust rings?
**A**: Thrust rings are manufactured from high-strength alloy steel and structural steel to withstand extreme forces, with components like bearing surfaces, main ring bodies, mounting flanges, and reinforcement ribs.

### Q: How does the thrust ring integrate with main jacking systems?
**A**: The thrust ring mounts via its flange to the jacking system framework, with its bearing surface distributing thrust loads evenly across reinforcement ribs to the main ring body, creating a stable reaction structure.
