About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X70X130
The SCT100X70X130 is a tandem multi-position cylinder delivering four fixed rod positions: 0 mm, 70 mm, 130 mm, and the full 200 mm travel. Each piston section generates a push force of 3927 N at 0.5 MPa, scaling to 7068 N at the0.9 MPa maximum operating pressure, driven through a rugged 25 mm diameter rod.
With a body length A(SCT) of 308 mm and a29 mm adjustable air cushion at each end, this double-acting unit decelerates loads smoothly across its discrete stops. It uses PT1/2 ports and an M20x1.5 rod thread, making it a direct fit for tasks needing repeatable, air-powered positioning without complex electronics.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X70X130 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 70 / 130 mm |
| Total travel | 200 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) | 70 mm |
| P2 (section 2) | 130 mm |
| P3 (both extended) | 200 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 SCT100X70X130 Is Used
Two-Station Diverter
Actuates a gate to three distinct positions—retracted, mid-stroke, and extended—to sort parts down two separate conveyor lanes from one infeed line.
Multi-Depth Pressing
Provides two controlled pressing depths (70 mm and200 mm) in a single cycle, ideal for a two-stage assembly or forming operation that needs a light touch followed by full insertion.
Sequential Clamping
Clamps a workpiece first with a partial stroke for alignment, then drives to the full200 mm position for high-force holding, all from one compact cylinder body.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X70X130 the Right Cylinder?
Choose the SCT tandem when your application requires multiple fixed stopping points from a single pneumatic axis, avoiding the cost and complexity of two separate cylinders with external hard stops. The100 mm bore offers a per-section push force of 3927 N at0.5 MPa; if your load is lighter, stepping down to the80 mm bore (2513 N push) can reduce air consumption and physical size. For replacement, match the100 mm bore, both the70 mm and130 mm strokes, PT port thread, and basic mounting to ensure a drop-in fit.
Given the200 mm total travel, ensure the load is guided if significant side forces are present to prevent rod bending and premature seal wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 70 + 130 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 SCT100X70X130 FAQ
It provides four discrete rod positions:0 mm (fully retracted),70 mm (first section extended),130 mm (second section extended), and200 mm (both sections extended). The stops are fixed by the two stroke lengths and are not infinitely adjustable.
The force is generated per single piston section. At0.5 MPa, one section provides 3927 N of push force and 3681 N of pull force. The two sections do not combine their force for a single push; each section acts independently to achieve the different stop positions.
