Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X15X150S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X15X150S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 15mm and 150mm give 4 controllable stop positions across a 165mm total travel, with a Ø40mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X15X150S
The SCT40X15X150S delivers four discrete rod positions—0 mm, 15 mm, 150 mm, and the full 165 mm extension—from a single tie-rod body. Each 40 mm bore piston section generates 628 N of push force at 0.5 MPa, making it a compact alternative to two separate cylinders for light sorting or diverting tasks.
A built-in magnet allows CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for end-of-stroke or mid-position confirmation. The 16 mm diameter rod resists side loads, and the 21 mm adjustable air cushion at each end decelerates the load smoothly across the 30–800 mm/s speed range.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X15X150S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 15 / 150 mm |
| Total travel | 165 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) | 15 mm |
| P2 (section 2) | 150 mm |
| P3 (both extended) | 165 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 SCT40X15X150S Is Used
Two-Way Part Diverting
The 15 mm stroke shifts a diverter gate to a first position, while the 150 mm stroke moves it fully across a conveyor, routing parts to two separate lanes from one compact actuator.
Staged Clamping
Apply a light 15 mm pre-clamp to align a workpiece, then drive the full 150 mm to engage the main clamp with 1130 N of force at 0.9 MPa, all from a single cylinder body.
Two-Depth Pressing
Insert a component 15 mm for a partial press fit, then extend to 150 mm for a secondary forming operation, using the built-in magnet for position feedback at each stop.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X15X150S the Right Cylinder?
Choose the SCT40X15X150S when your sequence requires a short 15 mm advance followed by a longer 150 mm stroke, or vice versa, without installing two actuators. If the per-section force is too low, stepping up to the 50 mm bore SCT50 provides 982 N of push at the same 0.5 MPa. For replacement, match the 40 mm bore, both the 15 mm and 150 mm section strokes, the PT port thread, the basic mounting style, and the -S magnet option to retain sensor compatibility.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 15 + 150 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 SCT40X15X150S FAQ
It provides four distinct rod positions: fully retracted (0 mm), the first section extended (15 mm), the second section extended (150 mm), and both sections extended for the total travel of 165 mm. The unequal strokes create four unique stops.
Yes, if your sequence needs only the 15 mm and 150 mm discrete stops. The SCT40X15X150S eliminates the need for two separate cylinders, mounting brackets, and flow controls, but note that the force output is 628 N per actuated section, not a combined total. Ensure your load does not need to be held at a mid-position without air pressure—an external lock is required for that.
