About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X125X80S
The SCT32X125X80S is a tandem multi-position pneumatic cylinder that provides four fixed rod positions: fully retracted (0 mm), 80 mm, 125 mm, and the total extended length of 205 mm. Each of the two piston sections, housed in a 32 mm bore, generates a push force of 402 N at 0.5 MPa, making it a compact solution for light-duty sorting or diverting tasks that require more than two end-of-stroke locations.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for reliable, non-contact position feedback at each stop. The 12 mm diameter rod and 21 mm adjustable air cushion at both ends of each section ensure smooth deceleration, while the PT1/8 port threads maintain compatibility with standard pneumatic fittings.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X125X80S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 125 / 80 mm |
| Total travel | 205 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) | 125 mm |
| P2 (section 2) | 80 mm |
| P3 (both extended) | 205 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 SCT32X125X80S Is Used
3-Way Part Diverting
Use the four discrete positions to guide parts from a single infeed conveyor to three separate outfeed lanes, with the 0 mm position serving as a home or fourth divert path.
Multi-Stop Label Applicator
Actuate to 80 mm for a wipe-down stroke and 125 mm for a tamp stroke on packages of different heights, using the 205 mm position for a secondary, deeper application.
Staged Clamping Fixture
Apply a light clamp force at the 80 mm stop and a full clamp force at the 125 mm stop, with the 205 mm position used for an ejection stroke, all controlled by pressurizing different cylinder sections.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X125X80S the Right Cylinder?
Choose the SCT when your application needs three or four distinct, repeatable stop points from a single, compact cylinder body, eliminating the complexity of mounting two separate cylinders with external hard stops. For applications requiring higher force, consider stepping up to the 40 mm bore SCT, which provides 628 N of push force per section at the same 0.5 MPa pressure. This SCT32X125X80S is a direct, form-fit replacement only for another AirTAC SCT with a 32 mm bore, 125 mm and 80 mm strokes, PT ports, basic mounting, and a built-in magnet.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 125 + 80 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 SCT32X125X80S FAQ
This cylinder provides four discrete rod positions: 0 mm (fully retracted), 80 mm (stroke 2), 125 mm (stroke 1), and 205 mm (stroke 1 + stroke 2). The positions are achieved by pressurizing section 2, section 1, or both sections simultaneously.
An SCT tandem cylinder integrates two piston sections on a single rod line within one body, providing multiple fixed stops without the alignment and mounting complexity of two separate cylinders. It is a simpler, more compact solution when you need 3 or 4 discrete, repeatable positions rather than full servo control.
