About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X80X30S
The SCT100X80X30S is a tandem multi-position cylinder delivering four distinct rod positions: 0 mm (fully retracted), 80 mm, 30 mm, and 110 mm total travel. Each 100 mm bore section generates a push force of 3927 N at 0.5 MPa, providing robust pneumatic actuation for sequencing tasks without complex electronics.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for reliable end-of-stroke or mid-position sensing. The cylinder features a 25 mm diameter rod, M20x1.5 rod thread, PT1/2 ports, and a 29 mm air cushion for smooth deceleration at each stop.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X80X30S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 80 / 30 mm |
| Total travel | 110 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) | 80 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 110 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 SCT100X80X30S Is Used
Two-Stage Sorting Gate
Uses the 80 mm stroke to extend a diverter arm into a main product flow, then the 30 mm stroke for a final precise push into a secondary lane, all controlled by two valve signals.
Multi-Depth Clamping
Provides a primary clamp at 30 mm for thin workpieces and a secondary clamp at 80 mm for thicker parts, with the full 110 mm travel used for part loading clearance.
Sequential Press Operation
Advances a tool to a pre-press position at 30 mm, then drives to the full pressing depth at 80 mm. The 110 mm retracted position allows complete tool change access.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X80X30S the Right Cylinder?
Choose the SCT100X80X30S when your process requires four fixed mechanical stops using a single compact assembly instead of two separate cylinders. The 80 mm and 30 mm strokes create an asymmetric position pattern ideal for a long advance with a short secondary push. If a lighter force profile is acceptable, stepping down to the 80 mm bore (2513 N push at 0.5 MPa) reduces air consumption while still offering the same multi-position logic.
For direct replacement, match the 100 mm bore, both stroke lengths (80 mm and 30 mm), PT port thread, and the -S magnet option. This is a basic mounting configuration; if panel mounting is needed later, FA or FB flange kits can be added. Ensure the rod is guided externally if the 110 mm total travel creates a side-load risk in your application.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 80 + 30 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 SCT100X80X30S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 80 mm (section 1 extended), 30 mm (section 2 extended), and 110 mm (both sections extended). The positions are fixed by the two stroke lengths and are not infinitely adjustable.
The SCT100X80X30S integrates two piston sections on a single common rod, ensuring coaxial alignment and reducing mounting footprint versus two separate cylinders with a coupler. It delivers the same 3927 N push force per section at 0.5 MPa, but with only one set of port connections and mounting brackets to manage.
