About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X30
The AirTAC SCT32X5X30 tandem cylinder delivers four distinct mechanical stops along a 35 mm total stroke, using two independently controlled 32 mm bore sections. By pressurising the sections individually or together, the rod extends to exactly 0, 5, 30, or 35 mm, making it a compact solution for short-throw, multi-step indexing. Each section generates 402 N of push force at 0.5 MPa, with the 12 mm diameter rod and 21 mm air cushion providing reliable deceleration.
This tie-rod design is built for precision rather than infinite positioning, so the discrete stops are highly repeatable. The body length A is 233 mm, keeping the assembly compact for machine builders. Standard features include PT1/8 ports and an M10x1.25 rod thread, with the cylinder operating on standard 40 µm filtered air across a 0.15–1.0 MPa pressure range.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X30 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X30 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 5 / 30 mm |
| Total travel | 35 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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) | 5 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 35 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCT32X5X30 Is Used
Two-Depth Precision Pressing
Achieve a shallow 5 mm pre-press and a deeper 30 mm final form in assembly fixtures, using the two distinct strokes for sequential operations without resetting tooling.
Micro-Sorting Gate
Use the four rod positions (0, 5, 30, 35 mm) to direct small parts into different chutes on a conveyor, with the 5 mm offset providing a subtle but reliable lane change.
Multi-Stop Label Applicator
Position a tamp pad at a 5 mm standby distance and a 30 mm application stroke, ensuring consistent label placement on varied product heights.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X30 the Right Cylinder?
Select the SCT32X5X30 when your application needs four fixed, repeatable stopping points in a very short 35 mm envelope, avoiding the complexity of two separate cylinders and external hard stops. If you require higher force per section, step up to the SCT40 series, where each 40 mm bore section provides 628 N of push at 0.5 MPa. For a direct replacement, match the 32 mm bore, both the 5 mm and 30 mm strokes, PT port thread, and basic mounting configuration exactly.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 5 + 30 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 SCT32X5X30 FAQ
This tandem cylinder provides four discrete mechanical stops: fully retracted (0 mm), the first section extended (5 mm), the second section extended (30 mm), and both sections extended for the total travel (35 mm).
Yes, it is designed to replace a setup with two SC32 cylinders mounted in series to achieve two independent strokes. Ensure the replacement matches the 32 mm bore, 5 mm and 30 mm strokes, PT1/8 ports, and basic mounting to maintain the same mechanical interface.
