About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X50X130
The SCT100X50X130 is a double-acting tandem cylinder that provides four fixed rod positions: 0 mm (fully retracted), 50 mm, 130 mm, and 180 mm (total travel). Built on a 100 mm bore with a rigid 25 mm diameter piston rod, each actuated section generates a push force of 3927 N at 0.5 MPa, scaling up to 7068 N at the maximum operating pressure of 0.9 MPa.
This tie-rod cylinder uses PT1/2 ports and incorporates a 29 mm adjustable air cushion in each section for controlled end-of-stroke deceleration. The body length A(SCT) is 308 mm, providing a compact footprint for its 180 mm total stroke. Standard TPU seals ensure reliable operation within a -20 to +70 °C range.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X50X130 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 50 / 130 mm |
| Total travel | 180 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) | 50 mm |
| P2 (section 2) | 130 mm |
| P3 (both extended) | 180 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 SCT100X50X130 Is Used
Two-Way Diverter Gate
Use the four discrete stops to direct product flow to two separate lanes. The 50 mm stroke opens a primary gate, while the 130 mm stroke fully extends to a secondary diverting position.
Multi-Depth Pressing
Achieve two distinct pressing depths in one cycle. The first section extends 50 mm for a pre-press or shallow form, and the second section adds 130 mm for a full-depth operation, all with 3927 N of force per stage.
Staged Part Transfer
Execute a pick-and-place sequence with a single cylinder. Retract to 0 mm to pick, extend to 50 mm for an intermediate inspection stop, and advance to 180 mm total travel for final placement.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X50X130 the Right Cylinder?
Choose the SCT100X50X130 when your application requires a compact, self-contained actuator for four-position sequencing without the complexity of two independent cylinders and external hard stops. The 50 mm and 130 mm strokes create distinct intermediate positions ideal for multi-step processes. If your force requirement is lower, stepping down to an 80 mm bore reduces the per-section push force to 2513 N at 0.5 MPa, which can lower air consumption. For a direct replacement, match the 100 mm bore, both 50 mm and 130 mm section strokes, PT port thread, and basic mounting configuration.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 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 SCT100X50X130 FAQ
This tandem cylinder provides four distinct rod positions: 0 mm (fully retracted), 50 mm (first section extended), 130 mm (second section extended), and 180 mm (both sections extended for total travel).
The SCT integrates both strokes into one tie-rod body, ensuring the rod line is perfectly aligned and eliminating the need to synchronize two separate cylinders, mounting brackets, and flow controls. It provides fixed, repeatable intermediate stops based on the 50 mm and 130 mm strokes without external hard stops.
