About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X75X90
The SCT80X75X90 is an 80 mm bore tandem cylinder delivering four fixed rod positions: fully retracted (0 mm), 75 mm, 90 mm, and the combined 165 mm total travel. Each 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, making it a robust choice for multi-stop material handling.
This tie-rod cylinder uses a 25 mm diameter rod with PT3/8 ports and a 28 mm adjustable air cushion at each end. The body length A(SCT) is 296 mm. Operating on filtered air from 0.15 to 1.0 MPa, it suits standard industrial temperatures from -20 to +70 °C with its default TPU seals.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X75X90 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 75 / 90 mm |
| Total travel | 165 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) | 75 mm |
| P2 (section 2) | 90 mm |
| P3 (both extended) | 165 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 SCT80X75X90 Is Used
Four-Way Sorting Gate
Use the four discrete positions (0, 75, 90, 165 mm) to divert packages onto three separate conveyor lanes from a single infeed, simplifying multi-line sortation.
Two-Depth Press Operation
Achieve a primary press depth at 75 mm and a secondary, deeper press at 165 mm for components requiring two-stage forming or insertion in one cycle.
Multi-Stop Part Transfer
Move a workpiece between four distinct stations on an assembly line—pick, two intermediate processes, and place—using a single actuator with fixed, repeatable stops.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X75X90 the Right Cylinder?
Selecting an SCT tandem cylinder eliminates the need for two separate cylinders and external hard stops to achieve four positions, simplifying the pneumatic circuit and saving space on the machine frame. This 80 mm bore model is well-suited to applications needing a push force of about 2513 N at standard line pressure; if a lighter force profile is acceptable, stepping down to a 63 mm bore provides 1559 N of push per section.
For a direct replacement, match the 80 mm bore, both the 75 mm and 90 mm strokes, PT port thread, and basic mounting configuration. Since the longer combined stroke reaches 165 mm, ensure the rod is supported if significant side loads are present, or consider an external guide to prevent rod bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 75 + 90 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 SCT80X75X90 FAQ
This tandem cylinder provides four distinct rod positions: fully retracted (0 mm), first section extended (75 mm), second section extended (90 mm), and both sections extended for the total travel of 165 mm. The stops are fixed by the two stroke lengths.
An SCT80 tandem unit replaces two individual cylinders and their mounting hardware with a single, compact actuator on one rod line. This reduces the number of valves and flow controls needed, simplifies alignment, and guarantees the relative positioning of the two strokes without external brackets.
