About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X200S
The SCT63X50X200S is a tandem multi-position cylinder that delivers four discrete rod stops: 0 mm (fully retracted), 50 mm, 200 mm, and the full 250 mm total travel. Each piston section provides a push force of 1559 N at 0.5 MPa, rising to 2805 N at the maximum 0.9 MPa operating pressure, driven through a 20 mm diameter rod.
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to be mounted directly on the tie-rod barrel for reliable end-of-stroke or mid-position sensing. The adjustable air cushion at each end, with a 28 mm cushion length, decelerates the load smoothly, while the PT1/4 port threads keep the unit compatible with standard pneumatic fittings.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X200S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X200S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 50 / 200 mm |
| Total travel | 250 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) | 50 mm |
| P2 (section 2) | 200 mm |
| P3 (both extended) | 250 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 SCT63X50X200S Is Used
Two-Stage Part Diverting
Use the 50 mm stroke to shift a diverter gate to a first lane and the 200 mm stroke to reach a second lane, with the full 250 mm travel clearing a reject path.
Multi-Depth Pressing
Actuate a pressing tool to a light contact depth at 50 mm and a full forming depth at 200 mm, using the 250 mm position for part ejection.
Sequential Stop Indexing
Drive a conveyor stop pin to three distinct heights: a low profile at 50 mm, a mid-height at 200 mm, and a full block at 250 mm for pallet control.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X200S the Right Cylinder?
Choose this 4-position SCT cylinder when your process needs a compact, all-in-one actuator to stop at 50 mm, 200 mm, and 250 mm, eliminating the complexity of two separate cylinders and external hard stops. If your application demands higher force, stepping up to the 80 mm bore provides 2513 N of push per section at 0.5 MPa. For a direct replacement, match the 63 mm bore, both 50 mm and 200 mm strokes, PT port threads, basic mounting, and the -S magnet option. With a combined stroke of 250 mm, ensure the rod is guided externally if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 200 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 SCT63X50X200S FAQ
This 4-position cylinder stops at 0 mm (fully retracted), 50 mm, 200 mm, and 250 mm (total travel). The positions are fixed by pressurizing the first section, the second section, or both simultaneously.
Order the identical model code SCT63X50X200S to match the 63 mm bore, 50 mm and 200 mm strokes, PT ports, basic mounting, and the integrated magnet for sensor compatibility. The per-section push force is 1559 N at 0.5 MPa.
