About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X150SH
The SCT32X160X150SH is a multi-position tandem cylinder that delivers four fixed rod positions—0 mm (fully retracted), 150 mm, 160 mm, and the combined 310 mm total travel—by pressurising its two piston sections independently. With a 12 mm rod and M10x1.25 rod thread, each section generates 402 N of push force at 0.5 MPa, scaling to 724 N at the maximum operating pressure of 0.9 MPa.
This variant includes a built-in magnet (S) for direct mounting of CMSG/DMSG/EMSG sensors, and high-temperature Viton (H) seals that shift the operating range from the standard -20–70°C up to 0–150°C. The PT1/8 ports and 21 mm air cushion on each section ensure smooth deceleration across all four discrete stop points, making it suitable for hot-environment sorting or multi-depth pressing tasks.

|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 160 / 150 mm |
| Total travel | 310 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) | 150 mm |
| P3 (both extended) | 310 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 SCT32X160X150SH Is Used
Hot-part diverting gate
Four-position blade (0, 150, 160, 310 mm) directs parts to three separate conveyor lanes in a heat-treating line, with Viton seals handling 120°C ambient air.
Two-depth hot-press eject
Retracts to 0 mm, extends to 150 mm for shallow part ejection, or 310 mm for deep-draw stripping, with sensor confirmation at each stop via the built-in magnet.
Multi-level adhesive dispensing
Positions a dispense head at 0 mm (safe/park), 150 mm, 160 mm, and 310 mm for applying beads at three different Z-heights on a single workpiece.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X150SH the Right Cylinder?
Choose this 32 mm bore SCT when you need four distinct mechanical stops in a compact tie-rod envelope, avoiding the complexity and plumbing of two separate cylinders with external hard stops. If the 402 N push force per section at 0.5 MPa is insufficient, stepping up to the 40 mm bore provides 628 N per section. For direct replacement, match the 32 mm bore, both the 160 mm and 150 mm strokes, PT port thread, basic mounting, and the -S magnet option; the Viton seal code must also be matched for high-temperature applications.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 160 + 150 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 SCT32X160X150SH FAQ
It provides four discrete mechanical stops because the two strokes differ (160 mm and 150 mm). The rod positions are 0 mm (retracted), 150 mm, 160 mm, and the total travel of 310 mm. These are fixed, hard stops—not infinitely variable.
Yes, it is a common replacement when you need three or four fixed stops on a single rod line. Ensure the replacement matches the 32 mm bore, both 160 mm and 150 mm strokes, PT ports, the built-in magnet, and the Viton seal if the original runs above 70°C.
