About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X400
The SCT100X100X400 is a double-acting multi-position tandem cylinder that provides four distinct mechanical stops along its stroke: 0 mm (fully retracted), 100 mm, 400 mm, and 500 mm (total travel). Each piston section delivers a powerful 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 material handling and positioning tasks.
Built on a robust tie-rod construction with a 25 mm diameter rod and an M20x1.5 rod thread, this cylinder features a 29 mm adjustable air cushion for smooth deceleration. The body length A(SCT) is 308 mm, and it uses a PT1/2 port. This is a genuine AirTAC component designed for reliable multi-stop operation in demanding industrial environments.

| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 100 / 400 mm |
| Total travel | 500 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) | 100 mm |
| P2 (section 2) | 400 mm |
| P3 (both extended) | 500 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 SCT100X100X400 Is Used
Two-Stage Sorting Gate
Operates a diverter gate with a partial-open position at 100 mm for small parcels and a full-open position at 500 mm for large packages on a conveyor line.
Multi-Depth Pressing
Provides a 100 mm pre-press stroke for alignment and a 500 mm full-travel stroke for the main forming operation in a heavy-duty assembly press.
Sequential Clamping
Executes a two-step clamping sequence, applying initial contact force at 400 mm of extension before a final high-force lock at the full 500 mm stroke.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X400 the Right Cylinder?
Select the SCT100X100X400 when your application requires a heavy-duty actuator capable of stopping at four fixed positions without the complexity of multiple cylinders and external hard stops. If your force requirements are lower, stepping down to an 80 mm bore reduces the per-section push force to 2513 N at 0.5 MPa. For a direct replacement, match the 100 mm bore, both the 100 mm and 400 mm strokes, the PT port thread, and the basic mounting configuration. For strokes of 300 mm or more, ensure the rod is externally guided to prevent side-loading and bending under high thrust.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 400 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 SCT100X100X400 FAQ
This tandem cylinder provides four discrete mechanical stop positions: 0 mm (retracted), 100 mm, 400 mm, and the full 500 mm extension. The positions are fixed by the two internal stroke sections and are selected by pressurizing the appropriate air ports.
The force is generated per actuated piston section. A single section provides 3927 N of push force and 3681 N of pull force at 0.5 MPa. At the maximum operating pressure of 0.9 MPa, the push force per section increases to 7068 N.
