About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X35X175S
The SCT32X35X175S is a tandem multi-position cylinder that delivers four discrete rod stops: 0 mm, 35 mm, 175 mm, and the combined total travel of 210 mm. Each 32 mm bore section generates 402 N of push force at 0.5 MPa, making it a compact solution for light-duty sorting or diverting tasks where multiple fixed endpoints are needed from a single pneumatic unit.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for reliable position feedback. The 12 mm diameter rod and PT1/8 ports keep the footprint small, while the 21 mm adjustable air cushion at each end section helps manage end-of-stroke impact across all four stop positions.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X35X175S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 35 / 175 mm |
| Total travel | 210 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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) | 35 mm |
| P2 (section 2) | 175 mm |
| P3 (both extended) | 210 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCT32X35X175S Is Used
Two-Stage Part Diverting
Use the 35 mm stroke to nudge a part onto a primary lane and the 175 mm stroke to push it fully onto a secondary conveyor, creating a compact 4-position diverter gate.
Multi-Depth Insertion
The rod stops at 35 mm for a shallow press-fit and 210 mm for full insertion, with the intermediate 175 mm position serving as a partial-engagement checkpoint.
Sensor-Controlled Staging
With the built-in magnet and CMSG sensors, the controller can confirm arrival at each of the four discrete positions before triggering the next machine sequence.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X35X175S the Right Cylinder?
Select the SCT32X35X175S when your application requires four distinct mechanical stops without the complexity of two separate cylinders and external hard stops. The unequal strokes give you a short 35 mm advance and a longer 175 mm second position, plus the full 210 mm extension, ideal for two-stage feeding or multi-depth insertion. If you need more force per section, step up to the 40 mm bore SCT40 which provides 628 N push at 0.5 MPa. For replacement, match the 32 mm bore, both 35 mm and 175 mm strokes, PT port thread, and the -S magnet option; basic mounting is standard, but FA or LB brackets can be added if your fixture requires them.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 35 + 175 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 SCT32X35X175S FAQ
This cylinder provides four discrete rod positions: fully retracted (0 mm), first section extended (35 mm), second section extended (175 mm), and both sections extended for the total travel of 210 mm. The positions are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, if your sequence needs exactly the 35 mm and 175 mm stops. The SCT tandem design eliminates the need to synchronize two cylinders and their mounting brackets. Ensure your replacement matches the 32 mm bore, both stroke lengths, PT ports, and the -S magnet if you use sensors.
