About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X30X100S
The SCT100X30X100S is a double-acting multi-position cylinder that provides four fixed rod positions: fully retracted (0 mm), 30 mm, 100 mm, and the combined total travel of 130 mm. Each piston section generates a powerful 3927 N of push force at 0.5 MPa, driven through a rigid 25 mm diameter rod with PT1/2 ports.
This tandem unit features a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing. With a 29 mm air cushion at each end and a body length of 308 mm, it is engineered for precise, repeatable multi-stop actuation in sorting and material handling tasks.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X30X100S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 30 / 100 mm |
| Total travel | 130 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) | 30 mm |
| P2 (section 2) | 100 mm |
| P3 (both extended) | 130 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 SCT100X30X100S Is Used
Two-Stage Part Diverting
Uses the 30 mm and 130 mm positions to route parts to two separate conveyor lanes, with the 100 mm position acting as a mid-stroke clearing stage.
Multi-Depth Pallet Stop
Provides three distinct stop heights (30, 100, 130 mm) for pallets of varying sizes on a gravity conveyor, precisely controlled by pressurizing the cylinder sections.
Sequential Clamping Station
Applies an initial low-force clamp at the 30 mm position, then a full-power clamp at the 130 mm total travel position, with sensor confirmation at each step via the built-in magnet.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X30X100S the Right Cylinder?
Choose this 4-position SCT model when your process needs two distinct extended stops plus a full-retract and full-extend position, eliminating the complexity of two separate cylinders and external hard stops. For higher thrust at each stop, stepping up to this 100 mm bore provides 3927 N of push force per section at 0.5 MPa, a significant increase over the 2513 N offered by the 80 mm bore version.
To guarantee a drop-in replacement, match the 100 mm bore, both strokes (30 mm and 100 mm), the PT port thread, and the built-in magnet (-S suffix). Since the 100 mm stroke section is relatively short, standard guiding is typically sufficient, but ensure the rod is supported if significant side loads are present.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 30 + 100 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 SCT100X30X100S FAQ
This cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 30 mm (section 1 extended), 100 mm (section 2 extended), and 130 mm (both sections extended for total travel). The positions are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, it is designed to do exactly that. One SCT100X30X100S replaces two SC100 cylinders (one with a 30 mm stroke, one with a 100 mm stroke) and their mounting hardware. Ensure the replacement matches the 100 mm bore, both strokes, PT ports, and the magnet option (-S) for sensor compatibility.
