About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X100X5
The SCT63X100X5 tandem cylinder delivers four fixed rod positions from two piston sections on a common axis: fully retracted (0 mm), 5 mm, 100 mm, and the combined total travel of 105 mm. This discrete stop set is ideal for applications requiring a short precision stroke and a longer feed stroke from one compact unit, eliminating the need for two separate actuators and their mounting hardware.
Built on a rugged tie-rod design with a 20 mm diameter rod and M16x1.5 rod thread, each 63 mm bore section generates 1559 N of push force at 0.5 MPa (2182 N at 0.7 MPa). The cylinder body has an A(SCT) length of 249 mm and uses a 28 mm adjustable air cushion on each section for smooth deceleration. Ports are PT1/4.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X100X5 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X100X5 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 100 / 5 mm |
| Total travel | 105 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) | 100 mm |
| P2 (section 2) | 5 mm |
| P3 (both extended) | 105 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 SCT63X100X5 Is Used
Two-Depth Pressing
Uses the 5 mm stroke for a light pre-press or part contact, then the 100 mm stroke for the full forming depth, giving two distinct pressing stages from one cylinder.
Sorting Gate Actuation
The 5 mm stop acts as a reject position, while the 100 mm stroke diverts parts down the main line, providing a compact 4-position diverter.
Micro-Adjust Feed
Combines a 5 mm fine-feed for tool engagement with a 100 mm rapid traverse, protecting delicate tooling before the main work stroke.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X100X5 the Right Cylinder?
Choose the SCT63X100X5 when your sequence needs a precise 5 mm locating stop and a 100 mm transfer stroke without the complexity of external hard stops or dual-cylinder setups. If the 5 mm stroke is too fine for your mechanical feedback, verify that your valve control can reliably pressurise only the short-stroke section to hit that position consistently. For higher per-section thrust, step up to the 80 mm bore, which provides 2513 N push at 0.5 MPa. When replacing an existing SCT, match the 63 mm bore, both the 100 mm and 5 mm strokes, PT port thread, and basic mounting to ensure identical form and function.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 5 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 SCT63X100X5 FAQ
It provides four discrete rod positions: 0 mm (fully retracted), 5 mm (first section extended), 100 mm (second section extended), and 105 mm (both sections extended). The stops are fixed by the two stroke lengths and are not infinitely adjustable.
Each 63 mm bore section generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. The two sections do not combine their force; each acts independently to move the rod to its designated stop.
