About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X10X140S
The AirTAC SCT40X10X140S is a tandem multi-position cylinder delivering four distinct rod positions: fully retracted (0 mm), 10 mm, 140 mm, and the combined total travel of 150 mm. Each piston section operates independently, providing a push force of 628 N at 0.5 MPa from the 40 mm bore, making it suitable for light-duty sorting or diverting tasks where two intermediate stops are required.
This model features a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for contactless position feedback. The 16 mm diameter rod and PT1/4 ports ensure reliable pneumatic connections, while the 21 mm adjustable air cushion at each end decelerates the load smoothly across the full 30-800 mm/s speed range.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X10X140S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 10 / 140 mm |
| Total travel | 150 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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) | 10 mm |
| P2 (section 2) | 140 mm |
| P3 (both extended) | 150 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SCT40X10X140S Is Used
Two-Stage Part Diverting
Uses the 10 mm stroke to clear a gate edge and the 140 mm stroke to push the part onto a separate conveyor lane, achieving four distinct positions for routing logic.
Multi-Depth Assembly Press
Provides a light touch at 10 mm for component alignment, a partial press at 140 mm, and a full-depth seat at 150 mm, all from one compact tandem unit.
Sequential Part Feeding
Advances a pusher plate to a staging point at 10 mm, then executes a 140 mm sweep to load the next workpiece, with sensors confirming each discrete stop.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X10X140S the Right Cylinder?
Select the SCT40X10X140S when an application requires four fixed mechanical stops without the complexity of two separate cylinders and external hard stops. The 10 mm and 140 mm stroke combination is ideal for a short initial advance followed by a longer secondary feed. If higher force is needed, consider stepping up to the 50 mm bore SCT series, which provides 982 N of push per section at the same pressure. For a direct replacement, match the 40 mm bore, both 10 mm and 140 mm strokes, PT thread, and the integrated magnet option; this cylinder is not dimensionally interchangeable with ISO 15552 profiles.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 10 + 140 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 SCT40X10X140S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 10 mm, 140 mm, and the combined total travel of 150 mm. These are achieved by pressurizing the first section, the second section, or both simultaneously.
It replaces two individual cylinders and their mounting hardware with a single, compact tandem body on one piston rod line, reducing alignment complexity and footprint. It provides fixed multi-stop capability without needing external hard stops or couplers between separate units.
