About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X80X25S
The SCT32X80X25S is a double-acting multi-position cylinder that delivers four fixed rod positions from its tandem piston design: fully retracted (0 mm), the first section extended (80 mm), the second section extended (25 mm), and both sections extended for a total travel of 105 mm. Each 32 mm bore section generates a push force of 402 N at 0.5 MPa, making it a compact solution for light-duty sorting or diverting tasks.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position feedback. The 12 mm diameter rod and PT1/8 ports keep the footprint small, while the 21 mm adjustable air cushion at each end decelerates the load smoothly. The body length A(SCT) is 233 mm.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X80X25S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X80X25S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 80 / 25 mm |
| Total travel | 105 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) | 80 mm |
| P2 (section 2) | 25 mm |
| P3 (both extended) | 105 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 SCT32X80X25S Is Used
3-Way Diverter Gate
Actuates a gate to three distinct positions for routing packages on a conveyor line, using the 0 mm, 80 mm, and 105 mm stops to direct flow.
Multi-Stop Label Applicator
Positions a tamp pad at 25 mm for a gentle touch and 105 mm for a high-force press, with the sensor confirming arrival at each discrete stop.
Two-Depth Part Insertion
Pushes a component to a 25 mm pre-insertion depth and then a full 105 mm seated depth in a fixture, using the tandem strokes for precise, repeatable staging.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X80X25S the Right Cylinder?
Choose the SCT32X80X25S when you need four distinct mechanical stops without the complexity of two separate cylinders and external hard stops. If your application requires more force, consider stepping up to the 40 mm bore SCT40 series, which provides 628 N of push per section at the same 0.5 MPa pressure. This cylinder is a direct replacement for another AirTAC SCT32 with 80 mm and 25 mm strokes, PT ports, and a built-in magnet. For a load that must be held at an intermediate position without air pressure, an external rod brake or pilot-operated check valve is required, as the air cushion does not lock the piston.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 80 + 25 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 SCT32X80X25S FAQ
It provides four distinct mechanical stop positions: 0 mm (fully retracted), 80 mm (first section extended), 25 mm (second section extended), and 105 mm (both sections extended). The positions are selected by pressurizing the appropriate cylinder ports.
Yes, the SCT32X80X25S is designed to replace a two-cylinder setup for multi-position tasks. It must match the bore (32 mm), both strokes (80 mm and 25 mm), port type (PT), and the built-in magnet option. It provides three positive stops from a single, compact tandem body.
