About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X10X156S
The SCT32X10X156S tandem cylinder delivers four fixed rod positions—0 mm, 10 mm, 156 mm, and 166 mm total travel—from a single compact tie-rod body. Each 32 mm bore section generates 402 N of push force at 0.5 MPa (724 N at 0.9 MPa), making it a precise multi-stop actuator for light sorting and diverting tasks.
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for end-of-stroke or mid-position confirmation. With a 12 mm rod, M10x1.25 rod thread, PT1/8 ports, and a 21 mm air cushion, it provides reliable deceleration at every stop without external shock absorbers.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X10X156S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X10X156S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 10 / 156 mm |
| Total travel | 166 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) | 10 mm |
| P2 (section 2) | 156 mm |
| P3 (both extended) | 166 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 SCT32X10X156S Is Used
Two-Way Part Sorting
Use the 10 mm stop to nudge a part onto a vision inspection station and the full 166 mm stroke to push accepted parts down a separate chute, all with sensor-confirmed positions.
Multi-Level Gate Control
Operate a sliding gate with a partially open position at 10 mm for small item metering and a fully open position at 156 mm for bulk flow, with the magnet confirming each state.
Two-Depth Pressing
Achieve a light pre-press at the 10 mm stop and a final seating depth at the 166 mm total travel, ideal for assemblies requiring a two-stage insertion process.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X10X156S the Right Cylinder?
Choose the SCT32X10X156S when you need four distinct mechanical stops without the complexity of two separate cylinders and external hard stops. The 10 mm short stroke gives a fine intermediate position, while the 156 mm stroke extends the reach for a second process step. If higher force is required, step up to the 40 mm bore SCT40 series, which provides 628 N of push per section at 0.5 MPa.
For direct replacement, match the 32 mm bore, both strokes (10 mm and 156 mm), PT port thread, basic mounting, and the -S magnet option. Note that with a combined stroke exceeding 150 mm, ensure the rod is adequately guided if side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 10 + 156 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 SCT32X10X156S FAQ
It provides four distinct rod positions: fully retracted (0 mm), the first section extended (10 mm), the second section extended (156 mm), and both sections extended for the total travel of 166 mm.
Yes, if your application requires two fixed stroke lengths (10 mm and 156 mm) from the same rod axis. The SCT32X10X156S consolidates this into a single tie-rod body, saving space and eliminating the need to synchronize two separate actuators.
