About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X250X250
The SCT32X250X250 is a double-acting multi-position cylinder that delivers three fixed rod positions: fully retracted, 250 mm, and 500 mm total travel. Each of its two piston sections generates 402 N of push force at 0.5 MPa, driven through a 12 mm diameter rod with M10x1.25 threads, making it suitable for light-duty sorting or diverting tasks.
Built on a tie-rod body with a 233 mm base length and 21 mm of adjustable air cushion at each end, this genuine AirTAC cylinder decelerates loads smoothly. The PT1/8 ports supply air to either section independently, allowing simple pneumatic control of the three stop points without complex electronics.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X250X250 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X250X250 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 250 / 250 mm |
| Total travel | 500 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 250 mm |
| P2 (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 (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 SCT32X250X250 Is Used
3-Position Sorting Gate
Directs packages to three different conveyor lanes by stopping the rod at 0, 250, and 500 mm, simplifying multi-outlet sorting systems.
Two-Depth Labeling
Applies labels at two distinct heights on a product. The cylinder extends to 250 mm for the first label and 500 mm for the second, then fully retracts.
Multi-Stop Part Feeding
Advances components in two 250 mm increments on an assembly line, presenting parts at an intermediate station and a final pick point.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X250X250 the Right Cylinder?
Choose the SCT32X250X250 when your application needs three defined positions from a single compact unit, avoiding the complexity of two separate cylinders and external stops. If higher force is needed, stepping up to the 40 mm bore provides 628 N of push per section at the same 0.5 MPa. For replacement, match the 32 mm bore, both 250 mm strokes, PT port thread, and basic mounting. With a 250 mm stroke per section, ensure the rod is guided if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 250 + 250 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 SCT32X250X250 FAQ
It has three distinct rod positions: 0 mm (fully retracted), 250 mm (first section extended), and 500 mm (both sections extended). The two equal strokes create these three stops.
Each of the two piston sections independently produces 402 N of push force and 345 N of pull force when operated at 0.5 MPa. The force does not combine; it acts per section.
