About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X10X80S
The SCT40X10X80S is a double-acting multi-position tandem cylinder that delivers four fixed rod positions: 0 mm (fully retracted), 10 mm, 80 mm, and the combined total travel of 90 mm. Each of its two 40 mm bore sections generates 628 N of push force at 0.5 MPa, making it suitable for light sorting or diverting tasks where two distinct intermediate stops are required. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for position feedback without extra brackets.
This model features a 16 mm diameter rod and PT1/4 ports with an M12x1.25 rod thread. The adjustable pneumatic cushion at each end cap absorbs impact over a 21 mm cushion length, protecting the cylinder during high-cycle operation. The body length A(SCT) is 235 mm plus the strokes, providing a compact footprint for machinery with limited space.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X10X80S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X10X80S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 10 / 80 mm |
| Total travel | 90 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) | 10 mm |
| P2 (section 2) | 80 mm |
| P3 (both extended) | 90 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 SCT40X10X80S Is Used
Two-Step Clamping
The 10 mm stroke provides a low-force pre-clamp or sensing position, while the 80 mm stroke delivers full clamping pressure, ideal for fragile workpieces that require a gentle initial contact.
Dual-Stop Diverter Gate
Use the 10 mm and 80 mm positions to route packages to two separate conveyor lanes. The integrated magnet confirms gate position at each stop, ensuring reliable sortation.
Staged Ejection
Eject parts in two phases: a 10 mm push to break stiction, then an 80 mm stroke to clear the part from the die or fixture. The 16 mm rod resists bending under the sequential load.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X10X80S the Right Cylinder?
Choose the SCT40X10X80S when your process needs a short initial advance of 10 mm followed by a longer 80 mm stroke, such as a two-step clamping or ejection sequence. If the 628 N push force per section is insufficient, stepping up to the 50 mm bore SCT50 series provides 982 N per section at the same 0.5 MPa pressure. For replacement, match the 40 mm bore, both the 10 mm and 80 mm strokes, the PT port thread, and the built-in magnet suffix -S to ensure sensor compatibility. The SCT mounting system supports FA/FB flanges, CA/CB devises, or LB feet if you later need to change the installation style.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 10 + 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 SCT40X10X80S FAQ
This tandem cylinder provides four discrete rod positions: 0 mm (fully retracted), 10 mm (first section extended), 80 mm (second section extended), and 90 mm (both sections extended). You select the position by pressurizing the appropriate combination of the two cylinder sections.
Direct replacement requires matching the AirTAC SCT40 series bore, both the 10 mm and 80 mm strokes, the PT1/4 port thread, and the built-in magnet for sensor compatibility. The SCT is a tie-rod cylinder, not an ISO 15552 profile cylinder, so dimensional interchangeability with profile types is not guaranteed.
