Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X25X25
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X25X25 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 25mm and 25mm give 3 controllable stop positions across a 50mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X25X25
The SCT32X25X25 is a tandem multi-position cylinder that provides three fixed rod positions: fully retracted (0 mm), 25 mm, and 50 mm total travel. Each of its two piston sections generates 402 N of push force at 0.5 MPa, making it a compact solution for light-duty sorting or diverting tasks.
This 32 mm bore tie-rod cylinder uses a 12 mm diameter rod and M10x1.25 rod thread. Its adjustable air cushion, with a 21 mm cushion length, ensures smooth deceleration at each stop, while the 233 mm body length A(SCT) fits neatly into space-constrained multi-stop fixtures.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X25X25 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X25X25 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 25 / 25 mm |
| Total travel | 50 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) | 25 mm |
| P2 (both extended) | 50 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 SCT32X25X25 Is Used
3-Way Part Sorting
Directs small components to three distinct lanes or bins by stopping the rod at 0, 25, or 50 mm, simplifying conveyor diverting logic.
Multi-Stop Feeding
Advances material strips or trays in precise 25 mm increments for step-by-step assembly or packaging operations.
Two-Depth Light Pressing
Applies a light insertion force at two controlled depths, ideal for installing seals or connectors to different set heights.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X25X25 the Right Cylinder?
Choose the SCT32X25X25 when a single actuator must reliably hit three mechanical stops without the complexity of two separate cylinders and external hard stops. For higher per-section thrust, step up to the 40 mm bore SCT, which delivers 628 N of push force at the same 0.5 MPa pressure. This model is a direct replacement for any existing AirTAC SCT32X25X25 with PT ports and basic mounting.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 25 + 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 SCT32X25X25 FAQ
It provides three distinct mechanical stop positions: 0 mm (fully retracted), 25 mm, and 50 mm (fully extended). This is because both piston sections have an identical 25 mm stroke.
Yes, in applications requiring three fixed positions. It eliminates the need for dual mounting brackets and external alignment, but ensure your load requirements match the single-section force of 402 N push at 0.5 MPa.
