About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X25
The AirTAC SCT100X100X25 is a double-acting multi-position tandem cylinder that delivers four fixed rod positions: 0 mm, 25 mm, 100 mm, and the combined 125 mm total travel. Each piston section operates independently, producing a push force of 3927 N at 0.5 MPa, rising to 7068 N at the maximum operating pressure of 0.9 MPa.
Built on a robust tie-rod design with a 25 mm diameter rod and M20x1.5 rod thread, this cylinder features a 29 mm adjustable air cushion at each end for smooth deceleration. The body length A(SCT) is 308 mm, and it uses PT1/2 ports, making it a compact yet powerful solution for sequenced linear movements.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X25 Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X25 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 100 / 25 mm |
| Total travel | 125 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) | 25 mm |
| P3 (both extended) | 125 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 SCT100X100X25 Is Used
Two-Stage Clamping
A primary clamp extends 100 mm for part clearance, then a secondary high-force clamp engages at the 25 mm position to secure a delicate component without over-travel.
Dual-Rate Pusher
Transfers a product 100 mm into a machine, then uses the 25 mm stroke for a final precise locating push against a datum, all from one compact cylinder body.
Sorting Gate Actuator
Controls a diverter gate with three positions: fully open at 125 mm, a mid-flow setting at 100 mm, and a low-flow bypass at the 25 mm extension.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X25 the Right Cylinder?
Select the SCT100X100X25 when your application requires two distinct extended positions and a partial retraction stop without the complexity of two separate cylinders and external hard stops. If you need a higher force class, the SCT100 is the largest bore in this series. For lower forces, stepping down to an 80 mm bore provides 2513 N of push per section at 0.5 MPa. As a direct replacement, ensure the alternative matches the 100 mm and 25 mm strokes, PT port thread, and basic mounting style.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 25 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 SCT100X100X25 FAQ
This tandem cylinder provides four discrete rod positions: fully retracted (0 mm), the first section extended (100 mm), the second section extended (25 mm), and both sections extended for the total travel of 125 mm.
No, like all standard pneumatic cylinders, it will drift if pressure is lost or the valve is centered. An external rod lock or pilot-operated check valve is required to mechanically hold a position without live air.
