About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X75
The SCT32X30X75 is a tandem multi-position cylinder that delivers four fixed rod positions: fully retracted (0 mm), 30 mm, 75 mm, and the combined 105 mm total travel. Each 32 mm bore section generates 402 N of push force at 0.5 MPa, making it suitable for compact diverting or sorting tasks where two distinct extended stops are required.
Built on a tie-rod design with a 12 mm rod and M10x1.25 rod thread, this cylinder includes a 21 mm adjustable air cushion in each section for end-of-stroke deceleration. The PT1/8 ports and standard TPU seals support an operating range of -20 to +70 °C, with a body length A(SCT) of 233 mm.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X75 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X75 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 30 / 75 mm |
| Total travel | 105 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) | 30 mm |
| P2 (section 2) | 75 mm |
| P3 (both extended) | 105 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 SCT32X30X75 Is Used
Two-Way Part Diverting
Extend to 30 mm for one lane and 105 mm for another, routing small components on a conveyor without multiple actuators.
Dual-Depth Labeling
Apply labels at two different heights (30 mm and 75 mm) on a product, using the discrete stops for consistent placement.
Staged Pin Insertion
Drive a locating pin to a pre-insertion depth of 30 mm, then a final press depth of 75 mm in a light assembly fixture.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X75 the Right Cylinder?
Select the SCT32X30X75 when your application needs two separate extension points without the complexity of two individual cylinders and external hard stops. The four-position capability (0, 30, 75, 105 mm) is ideal for sequencing two different feed lengths from a single actuator. If higher force is needed, stepping up to a 40 mm bore provides 628 N of push per section at the same 0.5 MPa.
For direct replacement, match the 32 mm bore, both strokes (30 mm and 75 mm), PT port thread, and basic mounting configuration. An identical AirTAC SCT32X30X75 model code ensures the same body length, rod diameter, and cushion performance.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 30 + 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 SCT32X30X75 FAQ
This cylinder provides four discrete positions: 0 mm (fully retracted), 30 mm, 75 mm, and the combined total travel of 105 mm. You achieve these by pressurizing the first section, the second section, or both simultaneously.
The SCT tandem design shares a common piston rod and body, saving space and eliminating the need to synchronize two separate actuators. It provides the same per-section force (402 N push at 0.5 MPa) but with a single, compact footprint and a total body length of 233 mm.
