About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X200X210S
The SCT100X200X210S is a 100 mm bore multi-position tandem cylinder that provides four distinct mechanical stop positions along its stroke: 0 mm (fully retracted), 200 mm, 210 mm, and the total extended travel of 410 mm. Each piston section delivers a robust push force of 3927 N at 0.5 MPa, scaling up to 7068 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy-duty sorting or staging tasks.
This model features a built-in magnet, designated by the 'S' suffix, allowing for direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for reliable end-of-stroke or intermediate position sensing. The cylinder body has a length of 308 mm and uses a 25 mm diameter piston rod with an M20x1.5 thread, offering excellent rigidity for the combined 410 mm total travel.

| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 200 / 210 mm |
| Total travel | 410 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 29 mm |
| Max stroke / section | Up to 500 mm standard |
Specifications follow the official AirTAC SCT (multi-position) datasheet. SCT is available in bores 32–100; each of the two sections has a 500 mm max standard stroke (800 mm max). Confirm against the product label before installation. Thread options: PT (standard) / G.
Stop Positions (4)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 200 mm |
| P2 (section 2) | 210 mm |
| P3 (both extended) | 410 mm |
Positions are set by pressurising section 1, section 2, or both. With equal strokes you get 3 distinct positions; with unequal strokes you get 4.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
Force is per actuated piston section (single-piston, same as the SC bore): push uses the full bore area, pull subtracts the rod area. Size with a safety margin.

Where the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X200X210S Is Used
Two-Stage Diverter Gate
Controls a chute or gate with three positions: closed (0 mm), partial divert to lane A (200 mm), and full divert to lane B (410 mm), using the 10 mm offset for fine flow adjustment.
Sequential Clamping Station
Applies an initial low-force clamp at 210 mm stroke before a secondary high-force press at the full 410 mm extension, with sensor confirmation at each stage via the built-in magnet.
Multi-Depth Assembly Press
Installs components to two different depths in one cycle. The rod stops precisely at 200 mm for a bushing seat and continues to 410 mm for a final bearing press, ensuring repeatable quality.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X200X210S the Right Cylinder?
Selecting this SCT model is ideal when an application requires two distinct extended positions plus full retraction, eliminating the complexity and alignment issues of two separate cylinders with external stops. The 200 mm and 210 mm stroke combination creates a precise 10 mm differential step between the intermediate positions. If a higher force is not required but a smaller footprint is, stepping down to an 80 mm bore SCT80X200X210S would provide 2513 N of push per section. A direct replacement must match the 100 mm bore, both 200 mm and 210 mm strokes, PT port thread, basic mounting, and the integrated magnet.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 200 + 210 mm suit your layout?
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Plumb the two sections to the correct valves for each stop.
- check Adjust end cushion screws for smooth stops.
- check Use SCT mounting accessory (FA / FB / CA / CB / LB).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X200X210S FAQ
This cylinder has four discrete mechanical stops. The rod can be positioned at 0 mm (fully retracted), 200 mm (first section extended), 210 mm (second section extended), and 410 mm (both sections fully extended). The 10 mm difference between the two strokes provides a very fine positioning step.
Yes, if your sequence requires stops at 200 mm and 410 mm. The SCT integrates both strokes into one tie-rod body, ensuring perfect axial alignment and reducing plumbing. Ensure the replacement matches the 100 mm bore, PT ports, and the 'S' magnet option for sensor compatibility.
