About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X55X95S
The SCT32X55X95S is a 32 mm bore multi-position tandem cylinder that delivers four fixed rod positions: fully retracted (0 mm), 55 mm, 95 mm, and the combined total travel of 150 mm. Each piston section provides a push force of 402 N at 0.5 MPa, making it a compact solution for light-duty sorting or diverting tasks.
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for reliable end-of-stroke or mid-position sensing. The 12 mm diameter rod and 21 mm adjustable air cushion at each end ensure smooth deceleration, while the PT1/8 ports keep the footprint small for space-constrained pneumatic panels.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X55X95S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X55X95S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 55 / 95 mm |
| Total travel | 150 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) | 55 mm |
| P2 (section 2) | 95 mm |
| P3 (both extended) | 150 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 SCT32X55X95S Is Used
Four-Position Diverter Gate
Routes packages or small parts to four separate lanes by pressurizing section 1, section 2, or both, achieving precise stops at 0, 55, 95, and 150 mm.
Multi-Depth Labeling Press
Applies labels at two different insertion depths by moving the tamp pad to the 55 mm or 95 mm position, with sensor confirmation at each stop via the built-in magnet.
Staged Part Feeding
Advances components in two distinct steps along a track, using the 55 mm stroke for a primary feed and the 95 mm stroke for a secondary push to the next station.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X55X95S the Right Cylinder?
Choose the SCT32X55X95S when your application requires four distinct mechanical stops without the complexity of servo control. It replaces two separate cylinders and external hard stops, simplifying plumbing and reducing the number of valves needed. For higher push force, step up to the 40 mm bore SCT, which provides 628 N per section at 0.5 MPa.
As a direct replacement, match the 32 mm bore, both strokes (55 mm and 95 mm), PT port thread, and the built-in magnet (-S suffix). This basic mounting version accepts the full range of SCT accessories, including FA/FB flanges or CA/CB clevises, which can be ordered separately and fitted later.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 55 + 95 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 SCT32X55X95S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 55 mm (section 1 extended), 95 mm (section 2 extended), and 150 mm (both sections extended). The positions are fixed by the two stroke lengths and are not infinitely variable.
Yes, it can replace a setup with two separate cylinders and external stops for two-position or three-position tasks, but the replacement must match the 32 mm bore, the specific 55 mm and 95 mm strokes, PT ports, and the -S magnet option. The force output remains 402 N push per actuated section, not a combined force.
