Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X30
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X30 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 30mm and 30mm give 3 controllable stop positions across a 60mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X30
The SCT32X30X30 is a tie-rod multi-position cylinder that provides three fixed rod positions: fully retracted, 30 mm, and 60 mm total travel. Each of its two 32 mm bore sections generates 402 N of push force at 0.5 MPa, making it a compact solution for light-duty sorting or diverting tasks.
This model uses a 12 mm diameter rod with an M10x1.25 thread and PT1/8 ports. The adjustable air cushion on each section is 21 mm long, and the total body length A(SCT) is 233 mm, allowing it to fit into tight machine envelopes where multiple stop points are needed.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X30 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 30 / 30 mm |
| Total travel | 60 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) | 30 mm |
| P2 (both extended) | 60 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 SCT32X30X30 Is Used
Two-Way Part Diverting
Extend to 30 mm for one lane or 60 mm for another, directing small components on a conveyor without needing multiple actuators.
Staged Ejection
Use the intermediate 30 mm position for a pre-eject stage and the full 60 mm stroke for final part release in assembly fixtures.
Dual-Depth Pressing
Achieve two controlled pressing depths in a single cycle, ideal for inserting pins or bushings to different set heights.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X30 the Right Cylinder?
Choose the SCT when a single actuator must reach two distinct extended positions without the complexity of two separate cylinders and external hard stops. The 32 mm bore is ideal for compact mechanisms; if higher force is needed, stepping up to the 40 mm bore provides 628 N of push per section at the same 0.5 MPa pressure.
For replacement, match the bore, both 30 mm strokes, PT port thread, and basic mounting. If the application involves a long tooling attachment, consider an external guide to protect the 12 mm rod from side loads.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 30 + 30 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 SCT32X30X30 FAQ
It provides three distinct mechanical stop positions: 0 mm (fully retracted), 30 mm (first section extended), and 60 mm (both sections extended). The stops are fixed by the cylinder's internal structure, not by external switches.
Yes, in applications requiring two fixed extension points on the same axis. It uses fewer valves and mounting brackets than two separate cylinders, but ensure the per-section force (402 N push at 0.5 MPa) meets your load requirement at each position.
