Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X40
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X40 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 5mm and 40mm give 4 controllable stop positions across a 45mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X40
The AirTAC SCT32X5X40 is a tie-rod multi-position cylinder that provides four fixed rod positions: 0 mm (fully retracted), 5 mm, 40 mm, and the combined total travel of 45 mm. This discrete positioning is achieved by pressurising one or both of its tandem piston sections, each delivering a push force of 402 N at 0.5 MPa.
Built with a 12 mm diameter rod and M10x1.25 rod-end thread, the cylinder uses PT1/8 ports and features an adjustable air cushion of 21 mm for smooth end-of-stroke deceleration. The body length A(SCT) is 233 mm, making it a compact solution for short-throw, multi-stop tasks where two separate cylinders would consume more space.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X40 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X40 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 5 / 40 mm |
| Total travel | 45 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) | 5 mm |
| P2 (section 2) | 40 mm |
| P3 (both extended) | 45 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 SCT32X5X40 Is Used
Two-Stage Sorting Gate
Uses the 5 mm and 40 mm positions to divert parts into three separate lanes on a conveyor, with the 45 mm total travel providing a fourth reject chute position.
Dual-Depth Insertion
Drives a tool to two precise insertion depths (5 mm and 40 mm) for installing seals or bushings at different levels within a single assembly station.
Multi-Stop Clamping Fixture
Clamps workpieces of two different thicknesses by stopping at 5 mm for thin parts and 40 mm for thicker ones, with the 45 mm position used for a wide-open loading state.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X40 the Right Cylinder?
Choose the SCT32X5X40 when your application needs two distinct short extensions plus a combined full-extension position without the complexity of external hard stops or dual-cylinder sequencing. If higher force is required, stepping up to the 40 mm bore SCT provides 628 N of push per section at the same 0.5 MPa pressure. For replacement, match the 32 mm bore, both the 5 mm and 40 mm strokes, PT port thread, and basic mounting configuration.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 5 + 40 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 SCT32X5X40 FAQ
This tandem cylinder provides four discrete positions: 0 mm (retracted), 5 mm, 40 mm, and the full combined stroke of 45 mm. The positions are achieved by applying pressure to the first section, the second section, or both simultaneously.
Yes, it can often replace two individually mounted cylinders used for two-position or three-position work, provided the strokes match your 5 mm and 40 mm requirements. Ensure the replacement SCT matches the PT port thread, basic mounting, and does not require a magnet unless the original code includes -S.
