Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X10
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X10 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 10mm and 10mm give 3 controllable stop positions across a 20mm total travel, with a Ø63mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X10
The SCT63X10X10 tandem cylinder delivers three fixed rod positions—0 mm, 10 mm, and 20 mm—by pressurising one or both of its 63 mm bore sections. Each section generates a push force of 1559 N at 0.5 MPa (2805 N at 0.9 MPa), making it suitable for short-stroke sorting gates and two-depth pressing fixtures where space is tight.
Built on a rugged tie-rod body with a 249 mm base length and 28 mm adjustable air cushion at each end, this model uses a 20 mm diameter piston rod with an M16x1.5 male thread. The standard PT1/4 ports and TPU seals suit general industrial air supplies filtered to 40 µm, operating reliably from -20 to +70 °C.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X10 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X10 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 10 / 10 mm |
| Total travel | 20 mm |
| Stop positions | 3 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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, 28 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) | 10 mm |
| P2 (both extended) | 20 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 SCT63X10X10 Is Used
Miniature Part Diverting
Uses the three discrete stops to route small components to separate lanes in a compact conveyor junction.
Two-Depth Pressing
Provides a precise 10 mm pre-press position and a full 20 mm final press depth for assembly operations.
Short-Stroke Ejector
Acts as a three-position ejector with a fully retracted idle, a 10 mm partial eject, and a 20 mm full strip.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X10 the Right Cylinder?
Choose the SCT63X10X10 when you need three positive mechanical stops without the complexity of external hard stops or two separate cylinders. For higher thrust in the same bore family, step up to the SCT80 series, which provides 2513 N of push per section at 0.5 MPa. If your application requires lighter actuation, the SCT50 bore offers 982 N per section.
To replace an existing unit, match the 63 mm bore, both 10 mm strokes, PT port thread, and basic mounting configuration. Always verify that the total 20 mm travel and the three-position logic match your machine's sequence before ordering.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 10 + 10 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 SCT63X10X10 FAQ
This cylinder provides three distinct mechanical stops: fully retracted (0 mm), first section extended (10 mm), and both sections extended (20 mm). The positions are fixed by the two 10 mm strokes and are not infinitely adjustable.
No. Like all standard pneumatic cylinders, the SCT63X10X10 will drift or drop if air pressure is exhausted. If you need to hold a load at the intermediate stop without live pressure, you must add an external rod lock or a pilot-operated check valve.
