Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X5X10
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X5X10 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 5mm and 10mm give 4 controllable stop positions across a 15mm total travel, with a Ø63mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X5X10
The SCT63X5X10 tandem cylinder provides four distinct rod positions—0, 5, 10, and 15 mm—by pressurising two piston sections on a common rod line. Each 63 mm bore section delivers 1559 N of push force at 0.5 MPa, making it ideal for compact, multi-stop sorting or diverting tasks where space is tight.
Built with a 20 mm diameter rod and M16x1.5 rod thread, this tie-rod cylinder includes a 28 mm adjustable air cushion on each end to manage end-of-stroke impact. The body length A(SCT) is 249 mm, and at 0.9 MPa, a single section pushes with 2805 N of force.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X5X10 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X5X10 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 5 / 10 mm |
| Total travel | 15 mm |
| Stop positions | 4 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 (4)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 5 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 15 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 SCT63X5X10 Is Used
Precision Sorting Gate
Diverts small parts to two different lanes using the 5 mm and 15 mm extended positions for a two-lane sorting system.
Multi-Depth Pressing
Applies two distinct pressing depths in a small assembly fixture, using the 5 mm and 10 mm stops for component insertion.
Compact Label Applicator
Positions a tamp pad at retracted, 5 mm, and 10 mm heights for applying labels to products of varying thicknesses.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X5X10 the Right Cylinder?
Select the SCT63X5X10 when you need four fixed mechanical stops from a single actuator, eliminating the complexity and cost of two separate cylinders with external hard stops. If your application requires higher force, consider stepping up to the 80 mm bore, which provides 2513 N of push per section at 0.5 MPa. For a direct replacement, match the 63 mm bore, both 5 mm and 10 mm strokes, PT port thread, and basic mounting configuration exactly.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 5 + 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 SCT63X5X10 FAQ
It provides four discrete rod positions: 0 mm (fully retracted), 5 mm, 10 mm, and the total travel of 15 mm. These are achieved by pressurising the first section, the second section, or both simultaneously.
No, the SCT is a tandem multi-position cylinder with two strokes. To replace it, you must match an AirTAC SCT of the same 63 mm bore, both 5 mm and 10 mm strokes, port thread, and mounting style. It is not interchangeable with a single-stroke SC cylinder.
