About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X10X100S
The SCT40X10X100S is a tandem multi-position pneumatic cylinder that delivers four fixed rod positions from two strokes on a single axis: fully retracted (0 mm), 10 mm, 100 mm, and the total travel of 110 mm. Each 40 mm bore piston section generates 628 N of push force at 0.5 MPa, making it a compact solution for light-duty applications requiring two distinct extended stops without the complexity of dual cylinders.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for end-of-stroke or mid-position confirmation. The 16 mm diameter rod and 21 mm adjustable air cushion at each end provide smooth deceleration, while the PT1/4 ports and standard PT thread keep integration straightforward.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X10X100S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 10 / 100 mm |
| Total travel | 110 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) | 100 mm |
| P3 (both extended) | 110 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 SCT40X10X100S Is Used
Two-Stage Sorting Gate
Use the 10 mm stroke to nudge a part into a measurement station and the full 110 mm travel to divert it to a reject lane, all with sensor feedback from the built-in magnet.
Dual-Depth Pressing
Achieve a light 10 mm pre-press position to align components, then drive to the 100 mm depth for final insertion, with the 628 N push force handling light assembly loads.
Multi-Stop Part Feeding
Index parts on a conveyor with three precise stop points: a home position, an intermediate 10 mm stop for inspection, and a 100 mm advanced position for the next operation.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X10X100S the Right Cylinder?
Choose the SCT40X10X100S when your process needs two different extended positions—such as a short 10 mm pre-load and a full 100 mm feed—from one compact actuator. If you require higher force, stepping up to the 50 mm bore SCT provides 982 N of push per section at 0.5 MPa. For a direct replacement, match the 40 mm bore, both strokes (10 mm and 100 mm), the PT port thread, and the built-in magnet; the basic mounting configuration uses the cylinder’s integral tie-rod nuts for fixture attachment.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 10 + 100 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 SCT40X10X100S FAQ
This tandem cylinder provides four discrete rod positions: 0 mm (fully retracted), 10 mm (section one extended), 100 mm (section two extended), and 110 mm (both sections extended, total travel). The positions are selected by pressurizing the appropriate cylinder sections.
Yes, in applications where two fixed strokes are needed on the same axis. The SCT40X10X100S combines two piston sections on a single rod line, saving space and eliminating the need to synchronize two separate actuators. Ensure the replacement matches the 10 mm and 100 mm strokes, PT1/4 ports, and the built-in magnet for sensor compatibility.
