Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X60X30
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X60X30 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 60mm and 30mm give 4 controllable stop positions across a 90mm total travel, with a Ø63mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X60X30
The SCT63X60X30 is a double-acting tandem cylinder that delivers four fixed rod positions—0 mm, 30 mm, 60 mm, and 90 mm—by pressurising one or both of its two piston sections. Each 63 mm bore section generates 1559 N of push force at 0.5 MPa, rising to 2805 N at 0.9 MPa, making it a robust choice for multi-stop diverting or sorting stations where space is limited.
Built on a tie-rod body with a 249 mm base length (A dimension), this model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable pneumatic cushion at each end (28 mm cushion length) decelerates the load smoothly, while the standard TPU seals suit operating temperatures from -20 to +70 °C.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X60X30 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X60X30 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 60 / 30 mm |
| Total travel | 90 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) | 60 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 90 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 SCT63X60X30 Is Used
Two-Way Diverter Gate
The 30 mm and 60 mm strokes create a compact diverter with a home position and two distinct gate angles, routing parts to separate lanes without needing two actuators.
Three-Depth Part Staging
Achieve retracted, 30 mm, 60 mm, and full 90 mm extension to stage components at three different depths for a sequential pressing or insertion operation.
Multi-Stop Label Applicator
The four discrete positions allow a labelling head to park at a safe distance, then extend to 30 mm for a low-tack, 60 mm for a wipe-down, and 90 mm for a full press.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X60X30 the Right Cylinder?
Choose the SCT63X60X30 when your application needs four distinct mechanical stops without the complexity of two separate cylinders and external hard stops. If the 1559 N push force per section (at 0.5 MPa) is insufficient, stepping up to the 80 mm bore SCT80X60X30 provides 2513 N per section; if it is excessive, the 50 mm bore SCT50X60X30 delivers 982 N per section. For a drop-in replacement, match the 63 mm bore, both strokes (60 mm and 30 mm), PT port thread, and basic mounting configuration.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 60 + 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 SCT63X60X30 FAQ
This cylinder provides four discrete rod positions: 0 mm (fully retracted), 30 mm (first section extended), 60 mm (second section extended), and 90 mm (both sections extended, total travel). The stops are fixed by the two stroke lengths and are not infinitely adjustable.
No, the SCT is a pneumatic cylinder and does not lock. If pressure is exhausted or a valve centers, the piston can drift. To hold a load at the 30 mm, 60 mm, or 90 mm position without live pressure, you must add an external rod lock or a pilot-operated check valve.
