About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X150X150
The SCT100X150X150 tandem cylinder delivers three precise, repeatable stop positions at 0 mm, 150 mm, and 300 mm by pressurizing its two piston sections. Each section provides 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 and positioning tasks.
Built on a durable tie-rod design with a 25 mm diameter rod and M20x1.5 rod thread, this model features a 29 mm adjustable air cushion on each end to absorb energy smoothly. The PT1/2 port connections and a body length of 308 mm ensure it integrates into existing pneumatic layouts without surprises.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X150X150 Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X150X150 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 150 / 150 mm |
| Total travel | 300 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) | 150 mm |
| P2 (both extended) | 300 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 SCT100X150X150 Is Used
3-Position Diverter Gate
Controls a gate on a conveyor line to sort packages into three separate lanes using the 0 mm, 150 mm, and 300 mm rod positions.
Two-Depth Clamping Fixture
Applies a light clamp at the 150 mm intermediate stop before a full-power 7068 N press at the 300 mm extended position for assembly operations.
Multi-Stop Material Stop
Acts as a programmable hard stop for sheet material, allowing an operator to select between two different feed lengths without manual adjustment.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X150X150 the Right Cylinder?
Choosing this SCT100X150X150 over two separate cylinders saves space and simplifies plumbing for applications needing three fixed stops. If your force requirement is lower, consider stepping down to the 80 mm bore, which provides 2513 N of push per section at 0.5 MPa. For a direct replacement, match the 100 mm bore, both 150 mm strokes, PT thread, and basic mounting configuration. With a total stroke of 300 mm, ensure the load is guided externally if significant side forces are present to prevent rod bending.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 150 + 150 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 SCT100X150X150 FAQ
This cylinder provides 3 discrete mechanical stops because both strokes are equal at 150 mm. The rod positions are fully retracted (0 mm), mid-extension (150 mm), and fully extended (300 mm).
Yes, it is a direct form-and-function match for any AirTAC SCT100X150X150 with PT ports and basic mounting. Ensure your system's operating pressure is within the 0.15-1.0 MPa range and that the 3927 N push force per section meets your load requirements.
