Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X160S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X160S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 30mm and 160mm give 4 controllable stop positions across a 190mm total travel, with a Ø40mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X160S
The SCT40X30X160S is a double-acting tandem cylinder that delivers four distinct rod positions from a single compact assembly. By pressurising the two 40 mm bore sections independently or together, the rod stops precisely at 0 mm, 30 mm, 160 mm, and the combined travel of 190 mm, making it ideal for sequencing tasks without complex controls.
Equipped with a built-in magnet, this model accepts CMSG/DMSG/EMSG sensors directly on the tie-rod barrel for reliable end-of-stroke or mid-position detection. Each piston section generates 628 N of push force at 0.5 MPa, and the 16 mm diameter rod with PT1/4 ports ensures robust, repeatable motion in a body length of just 235 mm plus strokes.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X160S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X160S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 30 / 160 mm |
| Total travel | 190 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) | 30 mm |
| P2 (section 2) | 160 mm |
| P3 (both extended) | 190 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 SCT40X30X160S Is Used
Two-Stage Part Diverting
Uses the 30 mm stroke for a preliminary gate and the 160 mm stroke for full diversion, routing parts to one of three lanes on a conveyor.
Multi-Depth Pressing
Provides a light touch at 30 mm extension for positioning, followed by a full 190 mm press stroke, ideal for assembly or forming operations.
Sequential Product Stopping
Acts as a two-stage stopper on a packaging line, stopping a leading carton at 160 mm and a trailing one at 30 mm with a single actuator.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X160S the Right Cylinder?
Choose the SCT40X30X160S when your application needs a 4-position actuator with a short primary stroke and a longer secondary stroke, eliminating the cost and complexity of two separate cylinders and valves. The built-in magnet simplifies adding position feedback without extra brackets. If higher force is required, consider stepping up to the 50 mm bore, which provides 982 N of push per section at the same pressure. For replacement, match the 40 mm bore, both strokes (30 mm and 160 mm), PT port thread, and the -S magnet option precisely.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 30 + 160 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 SCT40X30X160S FAQ
This cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 30 mm (first section extended), 160 mm (second section extended), and 190 mm (both sections extended). It is not infinitely adjustable.
It replaces two individually mounted cylinders and their flow controls with one tandem body, ensuring the two strokes share a common, precisely aligned rod axis. This saves space, reduces mounting hardware, and simplifies the pneumatic circuit while providing the same 628 N push force per section.
