About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X75S
The AirTAC SCT32X160X75S is a double-acting multi-position tandem cylinder that delivers four discrete rod stops from its two piston sections: 0 mm (fully retracted), 75 mm, 160 mm, and 235 mm (total travel). With a 12 mm rod and M10x1.25 rod thread, it provides a per-section push force of 402 N at 0.5 MPa, scaling to 724 N at the maximum operating pressure of 0.9 MPa.
A built-in magnet (the -S suffix) allows CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for end-of-stroke or intermediate position sensing. The cylinder uses PT1/8 ports and features an adjustable pneumatic cushion with a 21 mm cushion length, ensuring smooth deceleration at each stop without requiring external shock absorbers.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X75S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 160 / 75 mm |
| Total travel | 235 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) | 160 mm |
| P2 (section 2) | 75 mm |
| P3 (both extended) | 235 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 SCT32X160X75S Is Used
Multi-Stop Diverter Gate
Actuates a diverter gate to four distinct positions—fully closed, partially open at 75 mm, wide open at 160 mm, and full bypass at 235 mm—directing product flow to three separate lanes.
Three-Depth Assembly Press
Provides three controlled pressing depths plus a retracted home position for inserting components at different heights, using the 75 mm, 160 mm, and 235 mm stops for precise, repeatable insertion.
Staggered Part Feeding
Pushes parts onto a conveyor at two different advance distances (75 mm and 160 mm) to create staggered rows, with the full 235 mm extension clearing the lane for maintenance.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X75S the Right Cylinder?
Selecting an SCT32X160X75S means choosing a single compact unit over two separate cylinders and external hard stops to achieve four positions. The 32 mm bore is ideal for light sorting and diverting tasks; if your application demands more force, stepping up to the 40 mm bore provides 628 N of push per section at 0.5 MPa. For replacement, match the bore, both strokes (160 mm and 75 mm), the PT port thread, and the integrated magnet (-S) to maintain sensor compatibility. Since the combined stroke exceeds 300 mm, ensure the load is guided or supported to prevent rod bending and side-load wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 160 + 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 SCT32X160X75S FAQ
This tandem cylinder provides four discrete rod positions: 0 mm (fully retracted), 75 mm (section 2 extended), 160 mm (section 1 extended), and 235 mm (both sections extended, total travel). The positions are fixed by the two stroke lengths and are not infinitely adjustable.
The SCT combines two piston sections on a single common rod, which saves space, reduces mounting complexity, and guarantees coaxial alignment between the two strokes. You get four fixed mechanical stops without needing external brackets, couplers, or additional flow controls that two separate cylinders would require.
