About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X10X50
The SCT50X10X50 is a 50 mm bore multi-position pneumatic cylinder that provides four fixed rod positions: 0 mm (fully retracted), 10 mm, 50 mm, and the total travel of 60 mm. Each piston section generates a push force of 982 N at 0.5 MPa, making it a compact solution for short-stroke indexing tasks that require two distinct extended stops.
Built on a durable tie-rod design with a 20 mm diameter rod and M16x1.5 rod thread, this tandem cylinder uses PT1/4 ports and features a 21 mm adjustable air cushion. The body length A(SCT) is 243 mm, and the per-section thrust rises to 1767 N at the maximum operating pressure of 0.9 MPa.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X10X50 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X10X50 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 10 / 50 mm |
| Total travel | 60 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, 21 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) | 10 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 60 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 SCT50X10X50 Is Used
Two-Stage Part Ejection
Uses the 10 mm stroke for a gentle initial push to break a part free, followed by the full 50 mm stroke for complete ejection, preventing damage to delicate components.
Dual-Depth Stop Gate
Provides a 10 mm partial-open position for small item singulation and a 50 mm full-open position for bulk flow, controlling material release on a conveyor line.
Short-Stroke Clamping & Feed
The 10 mm position acts as a low-force clamp or locator, while the 50 mm stroke advances a feeder mechanism, all from one compact tandem cylinder body.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X10X50 the Right Cylinder?
Choose the SCT50X10X50 when your application needs a short 10 mm advance and a separate 50 mm positioning stroke from a single actuator. This saves the cost and plumbing of two individual cylinders. If higher force is needed, stepping up to the 63 mm bore provides 1559 N of push per section at 0.5 MPa. For a direct replacement, match the 50 mm bore, both the 10 mm and 50 mm strokes, PT port thread, and basic mounting configuration.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 10 + 50 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 SCT50X10X50 FAQ
This tandem cylinder has four discrete positions: 0 mm (fully retracted), 10 mm, 50 mm, and the combined total travel of 60 mm. You select the position by pressurizing the front section, rear section, or both simultaneously.
Each of the two piston sections independently produces 982 N of push force and 825 N of pull force at 0.5 MPa. The forces do not add together for a combined output; each section provides its rated thrust when actuated.
