Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X150X150
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X150X150 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 150mm and 150mm give 3 controllable stop positions across a 300mm total travel, with a Ø40mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X150X150
The SCT40X150X150 is a 40 mm bore multi-position pneumatic cylinder that delivers three fixed rod positions: fully retracted (0 mm), mid-stroke (150 mm), and full extension (300 mm). Each piston section generates 628 N of push force at 0.5 MPa, rising to 1130 N at 0.9 MPa, making it suitable for repetitive two-depth clamping or sorting tasks. The cylinder uses a 16 mm diameter rod with M12x1.25 threads and PT1/4 ports.
This tandem unit integrates two strokes on a single common rod, eliminating the complexity and misalignment risk of coupling two separate cylinders. Its tie-rod construction includes an adjustable air cushion on both sections, with a 21 mm cushion length, to manage end-of-stroke deceleration. The body length A(SCT) is 235 mm plus the two stroke lengths, keeping the assembly compact for its 300 mm total travel.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X150X150 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 150 / 150 mm |
| Total travel | 300 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 150 mm |
| P2 (both extended) | 300 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 SCT40X150X150 Is Used
Two-Depth Part Stamping
Actuate one section for a shallow 150 mm stamp and both sections for a full 300 mm deep draw, using a single compact cylinder.
3-Way Diverter Gate
Position a chute or gate at 0 mm (closed), 150 mm (divert to lane A), or 300 mm (divert to lane B) for product sorting.
Multi-Stop Pusher
Push cartons to three different conveyor lanes by stopping the rod at 0, 150, or 300 mm, controlled by two 5/2-way valves.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X150X150 the Right Cylinder?
Choose the SCT40X150X150 when you need three distinct mechanical stops without electronic feedback or external hard stops. It replaces setups that would otherwise require two individual SC40X150 cylinders with a coupling bracket, simplifying plumbing and saving space. Ensure your load's side forces are managed; for strokes of 150 mm per section, the 16 mm rod provides good rigidity, but a guide rail is recommended if the load is off-centre. For a direct replacement, match the 40 mm bore, both 150 mm strokes, PT thread, and basic mounting. If higher force is needed, step up to the SCT50 series, which provides 982 N of push per section at 0.5 MPa.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 150 + 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 SCT40X150X150 FAQ
It provides three distinct mechanical stop positions because both stroke sections are equal at 150 mm. The rod positions are 0 mm (fully retracted), 150 mm (one section extended), and 300 mm (both sections extended, total travel).
No, the SCT40X150X150 is a standard double-acting cylinder and will not hold its position under a loss of air pressure or when the valve centers. The piston can drift or drop. To safely hold a load at any of the three stops without live pressure, you must add an external rod lock or a pilot-operated check valve.
