About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X75X360S
The SCT32X75X360S is a double-acting multi-position tandem cylinder that delivers four fixed rod positions from two independent piston sections on a single rod line. With strokes of 75 mm and 360 mm, the reachable stops are 0 mm (fully retracted), 75 mm, 360 mm, and the total travel of 435 mm. Each section provides a push force of 402 N at 0.5 MPa, making it suitable for light sorting and diverting tasks.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors along the 12 mm diameter rod's barrel for position feedback. The tie-rod body has a length of 233 mm and features an adjustable air cushion of 21 mm at each end. Operating pressure ranges from 0.15 to 1.0 MPa, with a maximum push thrust of 724 N per section at 0.9 MPa.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X75X360S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 75 / 360 mm |
| Total travel | 435 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) | 75 mm |
| P2 (section 2) | 360 mm |
| P3 (both extended) | 435 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 SCT32X75X360S Is Used
Multi-Stop Diverter
Uses the four distinct positions (0, 75, 360, 435 mm) to route parts to four separate lanes on a conveyor, controlled by pressurizing the two cylinder sections independently or together.
Two-Depth Pressing
Provides a shallow 75 mm press depth and a deeper 360 mm press depth from the same actuator, with the option to combine them for a full 435 mm stroke when needed.
Staged Assembly Fixture
Positions a tooling plate at three intermediate heights plus home, enabling a single compact cylinder to handle multiple assembly steps without tool changes.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X75X360S the Right Cylinder?
An SCT cylinder replaces setups that would otherwise require two separate cylinders and external hard stops to achieve intermediate positions, simplifying plumbing and reducing footprint. For this 32 mm bore, if higher force is needed, stepping up to the 40 mm bore provides 628 N of push force per section at 0.5 MPa. When replacing this unit, match the 32 mm bore, both the 75 mm and 360 mm strokes, the PT port thread, and the integrated magnet. Since the 360 mm section stroke exceeds 300 mm, ensure the rod is adequately guided if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 75 + 360 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 SCT32X75X360S FAQ
This cylinder provides four discrete stop positions: 0 mm (fully retracted), 75 mm, 360 mm, and 435 mm (the sum of both strokes). The positions are achieved by pressurizing the first section, the second section, or both sections simultaneously.
Yes, the SCT32X75X360S is designed to replace two separate 32 mm bore cylinders with 75 mm and 360 mm strokes. Ensure the replacement matches the PT port thread and the -S magnet option for sensor compatibility.
