About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X10
The AirTAC SCT32X30X10 is a tie-rod multi-position cylinder that delivers four distinct mechanical stops along its stroke: 0 mm (fully retracted), 30 mm, 10 mm, and a total extended length of 40 mm. This is achieved by pressurizing either of its two 32 mm bore sections independently or simultaneously, offering simple pneumatic control without complex electronics.
Each piston section generates a push force of 402 N at 0.5 MPa, with a 12 mm diameter piston rod and M10x1.25 rod thread. The cylinder body length A(SCT) is 233 mm and it features a 21 mm adjustable air cushion, making it a compact yet robust solution for short-stroke, multi-stop tasks.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X10 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X10 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 30 / 10 mm |
| Total travel | 40 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) | 30 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 40 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 SCT32X30X10 Is Used
Two-Way Diverter Gate
Positions a flap gate to three distinct angles plus a home position, directing small parts down different chutes using the 0, 10, 30, and 40 mm stops.
Multi-Depth Label Press
Applies labels at two different pressing depths on a single product by stopping at 10 mm for a light tack and 30 mm for a full-pressure bond.
Staggered Part Feeding
Advances components in two precise increments of 10 mm and 30 mm onto an indexing conveyor, providing a simple fixed-sequence feed mechanism.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X10 the Right Cylinder?
Choosing the SCT32X30X10 over two separate cylinders eliminates the need for complex bracketry and ensures perfect axial alignment for your 4-position application. If higher force is required, consider stepping up to the 40 mm bore SCT, which provides 628 N of push per section at the same 0.5 MPa pressure. As a direct replacement, ensure the new unit matches the 32 mm bore, both the 30 mm and 10 mm strokes, PT port threads, and basic mounting configuration.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 30 + 10 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 SCT32X30X10 FAQ
This tandem cylinder provides 4 discrete stop positions: 0 mm (home), 30 mm (section 1 extended), 10 mm (section 2 extended), and 40 mm (both sections extended). The unequal strokes create four distinct hard stops.
Yes, the SCT32X30X10 is a direct form-factor replacement for two individually mounted cylinders with 30 mm and 10 mm strokes, provided they share the same axial line. It uses PT ports and basic mounting; verify your existing setup matches these specs.
