About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X60X70S
The SCT32X60X70S is a tandem multi-position cylinder that provides four fixed rod positions: fully retracted (0 mm), 60 mm, 70 mm, and 130 mm total travel. Each piston section delivers about 402 N of push force at 0.5 MPa, making it a compact solution for light-duty sorting or diverting tasks that need more than two end stops.
This 32 mm bore model uses a 12 mm diameter rod and PT1/8 ports, with a body length A of 233 mm. The built-in magnet (suffix -S) allows direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for reliable position feedback without external brackets.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X60X70S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X60X70S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 60 / 70 mm |
| Total travel | 130 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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, 21 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) | 60 mm |
| P2 (section 2) | 70 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCT32-63 Multi-Position Tandem Air Cylinder SCT32X60X70S Is Used
Multi-lane Diverter
Routes packages to four distinct conveyor lanes using the 0, 60, 70, and 130 mm stop positions for precise gate alignment.
Two-Depth Pressing
Executes a shallow 60 mm pre-press and a deeper 70 mm final press in sequence, with the 130 mm position used for part ejection.
Staged Part Transfer
Transfers components between four stations on an assembly line, using the discrete stops for accurate positioning at each pick-and-place point.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X60X70S the Right Cylinder?
Choose the SCT when you need up to four mechanical stops from a single compact unit rather than sequencing two separate cylinders. For higher thrust, step up to the 40 mm bore SCT which provides 628 N push per section at 0.5 MPa. This model is a direct replacement for an existing AirTAC SCT32 with 60 mm and 70 mm strokes, PT ports, and a magnet sensor option. If your application requires a pivoting mount, consider adding the CA rear clevis or CB double clevis kit.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 60 + 70 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 SCT32-63 Multi-Position Tandem Air Cylinder SCT32X60X70S FAQ
It provides four distinct mechanical stops: 0 mm (fully retracted), 60 mm, 70 mm, and 130 mm (fully extended, which is the sum of the two strokes).
Yes, if your process requires a 60 mm and a 70 mm stroke in a shared linear path. The SCT tandem design eliminates the need to synchronize two separate cylinders and their mountings, simplifying the machine layout.
