About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X240X60
The SCT63X240X60 tandem cylinder provides four distinct rod positions—0 mm, 60 mm, 240 mm, and full 300 mm extension—by pressurising its two piston sections independently or together. Each 63 mm bore section generates 1559 N of push force at 0.5 MPa, making it suitable for diverting or sorting tasks that need a long primary stroke and a short secondary stop.
Built on a tie-rod body with a 20 mm rod and M16x1.5 thread, this model uses PT1/4 ports and a 28 mm adjustable air cushion to manage end-of-stroke impact. The standard TPU seals suit ambient temperatures from -20 to +70 °C, and the basic configuration accepts direct mounting or optional brackets.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X240X60 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X240X60 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 240 / 60 mm |
| Total travel | 300 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) | 240 mm |
| P2 (section 2) | 60 mm |
| P3 (both extended) | 300 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 SCT63X240X60 Is Used
Two-Way Part Diverting
Uses the 60 mm and 240 mm stops to route parts from a main conveyor into two separate lanes based on a control signal.
Dual-Depth Pressing
Provides a 60 mm pre-press position and a full 300 mm pressing depth for assembling components with an intermediate forming step.
Multi-Stop Feeding
Advances material 240 mm for a primary feed and then 60 mm for a final precise placement in a packaging or assembly machine.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X240X60 the Right Cylinder?
This SCT replaces two separate cylinders or an SC with external stops when a process needs both a 240 mm travel and a precise 60 mm intermediate position. If a higher per-section force is required, stepping up to the 80 mm bore delivers 2513 N push at 0.5 MPa. For a drop-in replacement, match the 63 mm bore, both 240 mm and 60 mm strokes, PT port thread, and the basic mounting style. With the 240 mm section extended, ensure the load is guided to prevent rod bending from side forces.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 240 + 60 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 SCT63X240X60 FAQ
This model has four discrete stop positions: 0 mm (fully retracted), 60 mm, 240 mm, and 300 mm (fully extended). The stops are fixed by the two section strokes and are not infinitely adjustable.
No, the air cushion and multi-position design do not lock the rod. If pressure is lost or a valve centres, the piston can drift. An external rod brake or pilot-operated check valve is needed to hold a load at an intermediate stop.
