About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X75S
The SCT32X300X75S is a double-acting multi-position cylinder that delivers four fixed rod positions from two piston sections on a single axis. With strokes of 300 mm and 75 mm, the reachable stops are 0 mm (fully retracted), 75 mm, 300 mm, and the combined total travel of 375 mm. Each section provides 402 N of push force at 0.5 MPa, making it suitable for light-duty sorting or diverting tasks where a 12 mm rod and M10x1.25 rod thread are adequate.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing. The body length A(SCT) is 233 mm, and the adjustable air cushion at each end (21 mm cushion length) helps manage end-of-stroke impact. Operating on filtered air at 0.15–1.0 MPa, it uses PT1/8 ports and standard TPU seals for a temperature range of -20 to +70 °C.

| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 300 / 75 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) | 300 mm |
| P2 (section 2) | 75 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 SCT32X300X75S Is Used
Two-Lane Diverter Gate
Uses the 75 mm and 300 mm stops to direct parts into two separate lanes on a conveyor, with the 375 mm position acting as a third bypass or reject path.
Multi-Depth Light Press
Provides two controlled pressing depths (75 mm and 300 mm) for inserting components to different levels, with 724 N of force available per section at 0.9 MPa.
Staged Part Feeding
Advances a pusher plate to a 75 mm staging point for inspection, then to the full 375 mm position to transfer the part, all from one compact tandem unit.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X75S the Right Cylinder?
Choose the SCT32X300X75S when your application needs four distinct mechanical stops without the complexity of servo controls or multiple separate actuators. The 300 mm primary stroke handles the main travel, while the 75 mm secondary stroke provides a precise intermediate or offset position. If higher force is needed, stepping up to the 40 mm bore (SCT40) increases per-section push to 628 N at 0.5 MPa.
For replacement, match the 32 mm bore, both strokes (300 mm and 75 mm), PT port thread, and the built-in magnet (-S). Since the primary stroke is 300 mm, consider external guides or a rod-alignment coupler if the load applies significant side force, as the 12 mm rod can deflect under off-axis loads at full extension.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 300 + 75 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 SCT32X300X75S FAQ
It has four discrete mechanical stop positions: 0 mm (fully retracted), 75 mm (second section extended), 300 mm (first section extended), and 375 mm (both sections extended). The positions are fixed by the two stroke lengths and are selected by pressurizing the appropriate cylinder sections.
Yes, in many cases it can. It provides three extended positions (75, 300, 375 mm) from a single tie-rod body, which saves space and simplifies plumbing compared to mounting two standard SC32 cylinders back-to-back. Ensure the replacement matches the 32 mm bore, both strokes, PT ports, and the -S magnet option for sensor compatibility.
