It is mainly assembled on 3‑inch air‑expansion shafts. The 6‑12‑inch air‑expansion sleeve is clamped onto the 3‑inch air‑expansion shaft. It can also be fixed by the gripping force of the air‑expansion shaft itself to achieve the application effect of 6‑12 inches.
Air‑expansion sleeves are suitable for temporary alternative use. For long‑term operation, air‑expansion shafts of corresponding specifications are recommended.
