About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X175X25S
The SCT32X175X25S is a double-acting tandem cylinder that delivers four fixed rod positions from its two piston sections: 0 mm (fully retracted), 25 mm, 175 mm, and the total travel of 200 mm. With a 12 mm diameter rod and PT1/8 ports, each section provides a push force of 402 N at 0.5 MPa, making it a compact solution for light-duty multi-stop 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 body length A is 233 mm, and the adjustable air cushion at each end helps manage end-of-stroke impact within a speed range of 30-800 mm/s.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X175X25S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X175X25S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 175 / 25 mm |
| Total travel | 200 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) | 175 mm |
| P2 (section 2) | 25 mm |
| P3 (both extended) | 200 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 SCT32X175X25S Is Used
Two-Stage Sorting Gate
Uses the 25 mm stroke for a partial gate opening to divert small items and the full 200 mm stroke for a complete lane change, all from a single compact cylinder.
Multi-Depth Labeling
Positions a tamp pad at 0 mm (home), 25 mm (light touch), and 175 mm (full apply) for applying labels to products at varying heights on a conveyor.
Sequential Part Clamping
Provides a low-force initial clamp at the 25 mm position followed by a high-force full stroke at 175 mm, useful for delicate assembly processes.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X175X25S the Right Cylinder?
Select the SCT32X175X25S when your application requires a compact 32 mm bore actuator to index between four discrete positions without the complexity of two separate cylinders and external stops. The 175 mm and 25 mm stroke combination is well-suited for a long advance with a short secondary positioning step. If higher force is needed, stepping up to the 40 mm bore provides 628 N of push per section at the same pressure.
For a direct replacement, match the bore (32 mm), both strokes (175 mm and 25 mm), PT port thread, and the -S magnet option. The basic mounting configuration accepts standard SCT accessories like FA/FB flanges or LB feet if mounting needs change later.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 175 + 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 SCT32X175X25S FAQ
This tandem cylinder provides four discrete rod positions: 0 mm (retracted), 25 mm (first section extended), 175 mm (second section extended), and 200 mm (both sections extended, total travel).
The SCT32X175X25S integrates two strokes on a single common rod, guaranteeing fixed, repeatable intermediate positions without needing external hard stops, couplers, or complex sequencing valves. It saves space and simplifies the pneumatic circuit for multi-position tasks.
