About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X150S
The AirTAC SCT63X50X150S is a tandem multi-position cylinder that provides four discrete rod positions: 0 mm (fully retracted), 50 mm, 150 mm, and a total extended travel of 200 mm. This model features a built-in magnet, allowing for direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for contactless position feedback. Each 63 mm bore section delivers a push force of 1559 N at 0.5 MPa, rising to 2805 N at the maximum operating pressure of 0.9 MPa.
With a 20 mm diameter piston rod and PT1/4 ports, this cylinder has a 28 mm adjustable pneumatic cushion at each end to absorb energy and reduce noise. The TPU seals ensure reliable operation within a standard temperature range of -20 to +70 °C. The body length A(SCT) for this configuration is 249 mm, making it a compact solution for applications requiring a defined sequence of three or four stopping points without the complexity of servo systems.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X150S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 50 / 150 mm |
| Total travel | 200 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) | 150 mm |
| P3 (both extended) | 200 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 SCT63X50X150S Is Used
Multi-Stop Diverter Gate
Controls a diverter gate on a conveyor line, stopping at 0 mm (lane A), 50 mm (neutral), 150 mm (lane B), and 200 mm (lane C) to sort packages by destination.
Two-Depth Pressing Station
Executes a two-stage pressing operation: a rapid advance to a 150 mm pre-press position, followed by a final pressing stroke to the 200 mm total travel, with retraction back to 0 mm.
Sequential Part Feeding
Feeds components into a fixture in a defined sequence. The rod extends to 50 mm to push the first part, retracts to 0 mm, then extends to 150 mm and 200 mm to load subsequent parts.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X150S the Right Cylinder?
Select the SCT63X50X150S when your process requires a cylinder that can reliably stop at four fixed positions—for instance, an intermediate position at 50 mm and a second at 150 mm before reaching full extension at 200 mm. This integrated tandem unit is more compact and simpler to control than using two separate 63 mm bore cylinders with external hard stops. If higher force is needed, consider stepping up to the SCT80 series, where each section provides 2513 N of push force at 0.5 MPa. For a direct replacement, ensure the alternative matches the 63 mm bore, the 50 mm and 150 mm strokes, the PT port thread, and the built-in magnet (-S suffix).
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 150 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 SCT63X50X150S FAQ
This 4-position cylinder stops at 0 mm (fully retracted), 50 mm, 150 mm, and 200 mm (total travel). The positions are achieved by pressurizing the first section, the second section, or both sections simultaneously.
Yes, if your application requires the specific 50 mm and 150 mm stroke lengths. The SCT63X50X150S integrates both strokes into one tandem body, saving space and simplifying pneumatic circuitry. Ensure the replacement has the same -S magnet option and PT port thread for full compatibility.
