About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X100X400
The SCT80X100X400 tandem cylinder delivers four fixed rod positions for sequencing tasks without complex servo controls. By pressurising either or both of its 100 mm and 400 mm stroke sections, the 25 mm diameter rod can be precisely located at 0, 100, 400, or the full 500 mm total travel. Each actuated piston section generates 2513 N of push force at 0.5 MPa, rising to 4523 N at the maximum operating pressure of 0.9 MPa.
Built on an 80 mm bore tie-rod body with a total A-length of 296 mm plus strokes, this double-acting unit uses PT3/8 ports and features an adjustable pneumatic cushion of 28 mm at each end to manage deceleration. The standard TPU seals suit operating temperatures from -20 to +70 °C. For position sensing, external sensors can be mounted via the tie-rods, though this basic model does not include a built-in magnet.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X100X400 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 100 / 400 mm |
| Total travel | 500 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT3/8 |
| 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, 28 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) | 100 mm |
| P2 (section 2) | 400 mm |
| P3 (both extended) | 500 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SCT80X100X400 Is Used
Two-Stage Clamping
Use the 100 mm stroke for a rapid low-force approach to the workpiece, then engage the 400 mm section for the full-power clamping stroke, preventing collision damage.
Dual-Depth Part Insertion
Insert a component to a 100 mm pre-set depth in one station, then extend the rod further to 400 mm or full 500 mm travel to seat it in a deeper cavity at the next index.
Multi-Lane Diverter Gate
Position a diverter gate at 100 mm for lane one, 400 mm for lane two, or the full 500 mm to direct product to a third conveyor line, all from a single pneumatic unit.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X100X400 the Right Cylinder?
This four-position SCT replaces the complexity of two separate cylinders with external hard stops, reducing plumbing and alignment work. The 100 mm and 400 mm stroke combination is ideal for a short advance to a staging point followed by a longer push to a final position. If your application requires higher force, stepping up to the 100 mm bore provides 3927 N of push per section at 0.5 MPa. For a direct replacement, match the 80 mm bore, both the 100 mm and 400 mm strokes, PT port thread, and basic mounting. With the 400 mm section stroke being substantial, ensure the rod is adequately guided if significant side loads are present to prevent bending or uneven seal wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 400 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 SCT80X100X400 FAQ
This tandem cylinder provides four discrete, repeatable stop positions: 0 mm (fully retracted), 100 mm (first section extended), 400 mm (second section extended), and 500 mm (both sections extended for total travel).
Yes, if your sequence requires fixed stops at 100 mm and 400 mm. The SCT80X100X400 integrates both strokes onto a single rod line, saving space and eliminating the need to synchronize two separate cylinder movements. Ensure the replacement matches the PT3/8 ports and basic mounting.
