About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X100X80S
The AirTAC SCT40X100X80S is a double-acting multi-position tandem cylinder that delivers four fixed rod positions: 0 mm (fully retracted), 100 mm, 80 mm, and 180 mm (total travel). Each 40 mm bore piston section generates 628 N of push force at 0.5 MPa, making it a compact solution for sequencing tasks without complex controls.
This model includes a built-in magnet (-S suffix), allowing easy attachment of CMSG, DMSG, or EMSG sensors for end-of-stroke or intermediate position feedback. The 16 mm diameter rod and 21 mm adjustable air cushion at each end ensure smooth deceleration, while the tie-rod construction keeps maintenance simple.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X100X80S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 100 / 80 mm |
| Total travel | 180 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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) | 100 mm |
| P2 (section 2) | 80 mm |
| P3 (both extended) | 180 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SCT40X100X80S Is Used
Two-Way Part Sorting
Use the 100 mm stroke for a primary divert and the 80 mm stroke for a secondary lane, achieving three distinct routing positions from one compact cylinder.
Sequential Clamping
Apply a light initial clamp at the 80 mm position and a full-pressure hold at the 100 mm extension, controlling two clamping forces with a single actuator.
Multi-Stop Feeding
Advance material in two precise increments (80 mm and an additional 20 mm to reach 100 mm) for a two-step assembly or punching process.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X100X80S the Right Cylinder?
Choose the SCT tandem cylinder when you need two distinct, repeatable intermediate stops from a single pneumatic unit instead of wiring two separate actuators. This 40 mm bore model with 100 mm and 80 mm strokes is ideal for light sorting or two-step pushing. If higher force is needed, stepping up to the 50 mm bore provides 982 N of push per section at the same 0.5 MPa pressure.
For direct replacement, match an AirTAC SCT with a 40 mm bore, 100 mm first stroke, 80 mm second stroke, PT ports, basic mounting, and the -S magnet option. The 100 mm stroke on the first section is well within standard limits, so no external guide is strictly required for on-axis loads.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 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 SCT40X100X80S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 100 mm (first section extended), 80 mm (second section extended), and 180 mm (both sections extended).
Each piston section delivers 628 N of push force and 528 N of pull force when operated at 0.5 MPa. The force is per actuated section, not a combined total for the tandem assembly.
