Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X40X40S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X40X40S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 40mm and 40mm give 3 controllable stop positions across a 80mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X40X40S
The SCT32X40X40S is a multi-position tandem cylinder that delivers three fixed rod positions: fully retracted (0 mm), mid-extension (40 mm), and full extension (80 mm). Each 32 mm bore section generates 402 N of push force at 0.5 MPa, with a 12 mm diameter piston rod and M10x1.25 rod thread for secure tooling attachment.
Equipped with a built-in magnet (-S suffix), this model is ready for direct mounting of CMSG, DMSG, or EMSG sensors to confirm each discrete stop. The tie-rod construction uses PT1/8 ports and provides a 21 mm adjustable air cushion at both ends, with a body length A(SCT) of 233 mm. It operates on standard filtered air from 0.15 to 1.0 MPa.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X40X40S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X40X40S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 40 / 40 mm |
| Total travel | 80 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 40 mm |
| P2 (both extended) | 80 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 SCT32X40X40S Is Used
3-Way Diverter Gate
Actuates a flap or slide gate to three distinct positions—closed, bypass, and full open—for routing packages or bulk materials on a conveyor line.
Two-Depth Pressing
Provides a partial advance (40 mm) for pre-compression and a full advance (80 mm) for final pressing, ensuring consistent density in assembly or forming operations.
Multi-Stop Clamping
Clamps workpieces of two different thicknesses using the 40 mm and 80 mm stops, eliminating manual fixture adjustment in CNC machining or welding cells.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X40X40S the Right Cylinder?
Choose the SCT32X40X40S when a single cylinder must index between three fixed positions without the complexity of two separate actuators and external hard stops. For higher thrust, step up to the 40 mm bore SCT40 series, which provides 628 N of push per section at the same 0.5 MPa pressure. This model is a direct replacement for an existing AirTAC SCT32X40X40S with a magnet, matching the 32 mm bore, both 40 mm strokes, PT ports, and basic mounting configuration. Ensure the load is guided if side forces are present, as the tandem design extends the overall length.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 40 + 40 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 SCT32X40X40S FAQ
It provides 3 discrete mechanical stops because the two strokes are equal (40 mm each). The rod positions are 0 mm (fully retracted), 40 mm (first section extended), and 80 mm (both sections extended).
Yes, the -S suffix indicates a built-in magnetic band. This allows CMSG reed switches or DMSG/EMSG solid-state sensors to be mounted directly on the tie-rod barrel to detect each of the three positions.
