About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X75
The SCT32X150X75 tandem cylinder delivers four fixed rod positions—0 mm, 75 mm, 150 mm, and the full 225 mm extension—by pressurising its two piston sections independently or together. Each 32 mm bore section generates 402 N of push force at 0.5 MPa (724 N at 0.9 MPa), driven through a 12 mm diameter rod with PT1/8 ports.
A 21 mm adjustable air cushion at each end of the 233 mm body length A(SCT) decelerates the load smoothly, protecting the M10x1.25 rod-end threads from impact damage. This genuine AirTAC tie-rod design suits light-duty sorting and diverting tasks where a single cylinder must hit two intermediate stops without external hard stops.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X75 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X75 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 150 / 75 mm |
| Total travel | 225 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) | 150 mm |
| P2 (section 2) | 75 mm |
| P3 (both extended) | 225 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 SCT32X150X75 Is Used
Two-Way Diverter Gate
A single SCT32X150X75 shifts a flap between four fixed angles to route parcels down three separate conveyor lanes, eliminating two extra cylinders and their valve banks.
Multi-Depth Label Press
The rod stops at 75 mm for a light tack, 150 mm for a full-pressure bond, and 225 mm to eject the finished label, all from one compact tandem unit.
Staged Component Feed
Feeds electronic components to three pick points: a 75 mm pre-pick, a 150 mm inspection stop, and the 225 mm full-extend placement position.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X75 the Right Cylinder?
Choose the SCT32X150X75 when your sequence needs four distinct stopping points and the 32 mm bore's 402 N push force (at 0.5 MPa) is sufficient. If you require more thrust for the same position logic, stepping up to the 40 mm bore delivers 628 N push per section. The replacement must match the 32 mm bore, both strokes (150 mm and 75 mm), PT thread, and basic mounting; if the original carries a magnet suffix (-S), the new unit must include it for sensor compatibility.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 150 + 75 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 SCT32X150X75 FAQ
This tandem cylinder provides four discrete rod positions: 0 mm (fully retracted), 75 mm (section 2 extended), 150 mm (section 1 extended), and 225 mm (both sections extended, total travel).
Yes, if your application requires stops at 75 mm and 150 mm. The SCT tandem body integrates both strokes on one common rod line, saving mounting space and simplifying the pneumatic circuit compared to two individual cylinders with external stops.
