Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X100
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X100 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 100mm and 100mm give 3 controllable stop positions across a 200mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X100
The SCT32X100X100 is a tie-rod multi-position cylinder that provides three fixed rod positions: fully retracted (0 mm), mid-stop at 100 mm, and fully extended at 200 mm total travel. Each of its two piston sections generates 402 N of push force at 0.5 MPa, giving you predictable thrust for light sorting or diverting tasks.
This 32 mm bore tandem unit uses a 12 mm diameter rod and PT1/8 ports. The integrated air cushion, with a 21 mm cushion length, decelerates the piston smoothly at each end of the 200 mm combined stroke. The body length A(SCT) is 233 mm, making it a compact solution where space is tight.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X100 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X100 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 100 / 100 mm |
| Total travel | 200 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 100 mm |
| P2 (both extended) | 200 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 SCT32X100X100 Is Used
3-Position Diverter Gate
Use the three distinct stops to guide packages onto left, center, or right conveyor lanes in a compact sorting system.
Two-Depth Stamping Feed
Index a part into a press at a 100 mm pre-load position, then drive to the full 200 mm stroke for the final forming depth.
Multi-Stop Assembly Stop
Position a pallet at a 100 mm intermediate station for a gluing operation, then advance it to the 200 mm point for screw driving.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X100 the Right Cylinder?
Choose the SCT over two separate cylinders when you need a single, compact actuator to index between three fixed positions without complex external hard stops. If your load requires more force, step up to the 40 mm bore SCT, which provides 628 N of push per section at the same 0.5 MPa pressure. For replacement, match the 32 mm bore, both 100 mm strokes, PT port thread, and basic mounting. If either stroke were 300 mm or more, consider an external guide to prevent rod bending under side loads.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 100 + 100 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 SCT32X100X100 FAQ
It has three distinct rod positions because both stroke sections are equal at 100 mm. The reachable positions are 0 mm (fully retracted), 100 mm (mid-stroke), and 200 mm (fully extended).
Yes, in applications requiring a three-position sequence. A single SCT32X100X100 replaces two SC32X100 cylinders and their mounting hardware, simplifying the pneumatic circuit and reducing the machine footprint.
