About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X75X300S
The AirTAC SCT32X75X300S is a double-acting multi-position tandem cylinder providing four distinct rod positions: 0 mm, 75 mm, 300 mm, and 375 mm total travel. Each piston section generates 402 N of push force at 0.5 MPa, making it suitable for light-duty sorting and diverting tasks where multiple fixed stops are required without complex controls.
This model includes a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection at each position. The 12 mm diameter rod and PT1/8 ports keep the unit compact, while the 21 mm adjustable air cushion at each end protects against impact.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X75X300S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X75X300S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 75 / 300 mm |
| Total travel | 375 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) | 300 mm |
| P3 (both extended) | 375 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 SCT32X75X300S Is Used
Multi-Stop Diverter
Routes packages to four separate conveyor lanes using the 75 mm and 300 mm intermediate stops for precise gate positioning.
Two-Depth Press
Provides a shallow 75 mm pressing depth and a deep 300 mm stroke for two-stage assembly or forming operations.
Sensor-Controlled Feeding
The integrated magnet allows sensors to confirm each of the four positions, ensuring accurate part transfer in automated cells.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X75X300S the Right Cylinder?
Choose the SCT32X75X300S when your application needs four fixed stopping points from a single compact actuator. For higher force at each stop, step up to the 40 mm bore SCT which delivers 628 N push per section. This model is a direct replacement for any AirTAC SCT32 with 75 mm and 300 mm strokes, PT ports, and a magnet sensor option. Ensure external guides are used if the 300 mm stroke section encounters significant side loads.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 75 + 300 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 SCT32X75X300S FAQ
It has four discrete positions: fully retracted (0 mm), first section extended (75 mm), second section extended (300 mm), and both sections extended (375 mm).
No, the SCT is a tandem cylinder for multi-position use. It replaces another SCT32 with 75 mm and 300 mm strokes, PT ports, and a magnet. It cannot substitute a single-stroke SC cylinder.
