About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X80X80
The SCT32X80X80 is a tandem multi-position cylinder that delivers three fixed rod positions: fully retracted (0 mm), 80 mm, and the total combined travel of 160 mm. Achieving these discrete stops is done by pressurising either or both of its two 32 mm bore sections, each delivering a push force of 402 N at 0.5 MPa. The unit uses a 12 mm diameter piston rod and features an M10x1.25 rod-end thread.
Built on a tie-rod design with a body length A of 233 mm, this double-acting cylinder includes adjustable pneumatic cushioning at both ends with a 21 mm cushion length. It operates with filtered air from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa. The standard TPU seals suit a temperature range of -20 to +70 °C, and the PT1/8 ports are standard.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X80X80 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 80 / 80 mm |
| Total travel | 160 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) | 80 mm |
| P2 (both extended) | 160 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 SCT32X80X80 Is Used
3-Position Sorting Gate
Directs small packages to three separate conveyor lanes by stopping at retracted, mid-stroke (80 mm), and full extension (160 mm).
Multi-Level Part Staging
Positions a lightweight component at two different insertion depths for a sequential assembly process, using the 80 mm and 160 mm stops.
Dual-Stroke Clamping Fixture
Applies a preliminary clamp at 80 mm extension before a final high-pressure clamp at the full 160 mm stroke, all from a single compact unit.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X80X80 the Right Cylinder?
Choose the SCT32X80X80 when a compact, three-position actuator is more cost-effective and simpler to control than two separate cylinders with external stops. This model is ideal for applications requiring a light push force of 402 N at standard line pressure. If a higher force is needed, stepping up to the 40 mm bore SCT40X80X80 provides 628 N of push per section at the same 0.5 MPa. For a direct replacement, match the 32 mm bore, both 80 mm strokes, PT port thread, and basic mounting configuration.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 80 + 80 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 SCT32X80X80 FAQ
This model provides three distinct mechanical stop positions because both piston sections have an equal 80 mm stroke. The rod can be positioned at 0 mm (fully retracted), 80 mm (one section extended), and 160 mm (both sections extended).
Yes, if your application requires the rod to stop at 0, 80, and 160 mm. The SCT tandem cylinder achieves this in a single body with a common rod, simplifying mounting and eliminating the need to synchronize two separate actuators. Ensure the per-section force of 402 N at 0.5 MPa meets your load requirements.
