About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X500X290S
The SCT32X500X290S is a tandem multi-position cylinder delivering four fixed rod positions: 0 mm (fully retracted), 290 mm, 500 mm, and a total extended travel of 790 mm. Each piston section generates a push force of 402 N at 0.5 MPa, providing reliable actuation for light-duty sequencing tasks.
This 32 mm bore model features a 12 mm diameter rod, M10x1.25 rod thread, and PT1/8 ports. The built-in magnet (suffix -S) allows direct mounting of CMSG/DMSG/EMSG sensors for position feedback. Its tie-rod body has a base length A(SCT) of 233 mm and a 21 mm air cushion for smooth end-of-stroke deceleration.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X500X290S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 500 / 290 mm |
| Total travel | 790 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) | 500 mm |
| P2 (section 2) | 290 mm |
| P3 (both extended) | 790 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 SCT32X500X290S Is Used
Multi-Stop Diverter Gate
Positions a diverter gate at four distinct angles—retracted, mid-point, extended, and full-travel—to route packages to separate conveyor lines based on barcode data.
Two-Depth Pressing Station
Executes a two-stage pressing sequence: a partial stroke (290 mm) for initial forming, followed by a full 500 mm stroke for final compaction, with the 790 mm position used for part ejection.
Sequential Component Insertion
Inserts two different components into an assembly at controlled depths of 290 mm and 500 mm, using the 790 mm total extension to clear the fixture for the next cycle.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X500X290S the Right Cylinder?
This model suits applications needing four distinct stop points without the complexity of servo control. The 500 mm front section stroke is at the standard limit; for longer reaches, consider stepping up to the 40 mm bore (628 N push at 0.5 MPa) to better handle increased rod bending moments. When replacing, match the bore, both strokes (500 and 290 mm), PT thread, and the -S magnet option. Since the front stroke is 500 mm, ensure the load is guided or supported to prevent side-loading and premature rod bearing wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 500 + 290 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 SCT32X500X290S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 290 mm (second section extended), 500 mm (first section extended), and 790 mm (both sections fully extended). The positions are fixed by the cylinder's internal structure, not infinitely variable.
Yes, in many cases. The SCT32X500X290S consolidates two 32 mm bore strokes (500 mm and 290 mm) into a single, compact tandem body with a common rod. This eliminates the need for complex external bracketry and alignment of two separate cylinders, provided the discrete 4-position sequence matches your process.
