Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 300mm and 300mm give 3 controllable stop positions across a 600mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300
The SCT32X300X300 is a double-acting tandem cylinder that provides three fixed rod positions: fully retracted (0 mm), the first section extended (300 mm), and both sections extended for a total travel of 600 mm. Each 32 mm bore section generates 402 N of push force at 0.5 MPa, making it a compact solution for light-duty sorting or diverting tasks where two distinct extended stops are required from a single tie-rod body.
Built with a 12 mm diameter piston rod and PT1/8 ports, this model includes a 21 mm adjustable air cushion in each section to decelerate the load smoothly at the end of the 300 mm strokes. The body length A(SCT) is 233 mm, and the push force rises to 724 N per section at the maximum operating pressure of 0.9 MPa.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 300 / 300 mm |
| Total travel | 600 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) | 300 mm |
| P2 (both extended) | 600 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 SCT32X300X300 Is Used
3-Way Diverter Gate
Use the three discrete positions (0, 300, 600 mm) to direct parts down a central, left, or right lane on a conveyor, simplifying pneumatic routing with a single actuator.
Two-Stage Part Ejection
Eject a part with a 300 mm stroke for one product size, or extend fully to 600 mm for a taller variant, eliminating manual changeover between batches.
Multi-Stop Labeling Head
Position a labeling head at a 300 mm standby position for large boxes and a 600 mm position for pallet application, achieving two working heights from one cylinder.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300 the Right Cylinder?
Select the SCT32X300X300 when your application needs a compact, three-position actuator without the complexity of two separate cylinders and external hard stops. For higher thrust, consider stepping up to the SCT40 bore, where each section provides 628 N of push force at 0.5 MPa. This model is a direct, form-fit replacement for another AirTAC SCT32 with 300 mm strokes, PT ports, and basic mounting.
With a 300 mm stroke per section, ensure the rod is properly guided if the load applies significant side force, as the 12 mm rod can be susceptible to bending under off-axis loads.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 300 + 300 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 SCT32X300X300 FAQ
This model provides 3 distinct mechanical stops because both strokes are equal at 300 mm. The rod positions are 0 mm (fully retracted), 300 mm (first section extended), and 600 mm (both sections extended for total travel).
Yes, in many cases. It provides the same two extended stops in a single, pre-aligned tie-rod body, reducing mounting hardware and ensuring the stroke relationship is fixed. It is a direct replacement for another AirTAC SCT32X300X300 with PT ports and basic mounting.
