About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X50X50
The SCT100X50X50 is a double-acting multi-position tandem cylinder that provides three fixed rod positions: fully retracted (0 mm), 50 mm, and 100 mm total travel. Each piston section generates a push force of 3927 N at 0.5 MPa, scaling to 7068 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy-duty sorting or two-stop pressing operations.
This 100 mm bore model features a 25 mm diameter piston rod and an M20x1.5 rod thread, with a PT1/2 port for pneumatic connections. The adjustable air cushion at each end has a 29 mm cushion length, and the tie-rod body has a base length A of 308 mm, ensuring robust performance in industrial automation tasks.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X50X50 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 50 / 50 mm |
| Total travel | 100 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 50 mm |
| P2 (both extended) | 100 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 SCT100X50X50 Is Used
3-Position Diverter Gate
Controls a gate on a conveyor line with three fixed positions: closed (0 mm), partial divert to lane A (50 mm), and full divert to lane B (100 mm), using simple pneumatic control.
Two-Depth Pressing Station
Executes a two-stage pressing operation where the first 50 mm stroke provides a pre-clamp and the full 100 mm stroke delivers the final high-force press, all from one compact cylinder.
Multi-Stop Material Stop
Acts as a retractable stop with three positions to halt pallets or workpieces at two different locations along a gravity roller conveyor, enabling batching or sequencing.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X50X50 the Right Cylinder?
Choose the SCT100X50X50 when a single actuator must reliably index between three distinct mechanical stops without the complexity of two separate cylinders and external hard stops. For applications requiring higher force, this 100 mm bore is the largest in the SCT range; if a lighter, more compact solution is acceptable, stepping down to an 80 mm bore (2513 N push at 0.5 MPa per section) may reduce air consumption and physical footprint.
This model is a direct replacement for another AirTAC SCT100X50X50 with PT ports and basic mounting. When ordering a replacement, ensure both stroke sections (50 mm and 50 mm) and the port thread match your existing installation.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 50 + 50 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 SCT100X50X50 FAQ
This cylinder provides 3 distinct mechanical stop positions because both stroke sections are equal at 50 mm. The rod positions are 0 mm (fully retracted), 50 mm (first section extended), and 100 mm (both sections extended for total travel).
The force is generated by a single piston section. At 0.5 MPa, it provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The two sections do not combine force for a multi-position move.
