About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X131X131
The SCT32X131X131 tandem cylinder delivers three fixed rod positions—0 mm, 131 mm, and 262 mm—by pressurising either or both of its two piston sections. Each section provides a push force of 402 N at 0.5 MPa, making it suitable for light sorting or diverting tasks where intermediate stops are required without complex controls.
Built on a 32 mm bore tie-rod body with a 12 mm diameter rod and M10x1.25 rod-end thread, this model has a 21 mm adjustable air cushion at each end. The total body length A is 233 mm, and the PT1/8 ports accept standard pneumatic fittings.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X131X131 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X131X131 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 131 / 131 mm |
| Total travel | 262 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 131 mm |
| P2 (both extended) | 262 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 SCT32X131X131 Is Used
Two-Lane Diverter
Positions a package diverter gate to three lanes using the 0, 131, and 262 mm stops, controlled by two 3/2-way valves.
Multi-Level Part Staging
Stages small components at two different heights above a conveyor, with the fully retracted position allowing free belt passage.
Two-Depth Pressing
Drives a forming tool to a partial depth at 131 mm for pre-forming, then to the full 262 mm depth for final sizing.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X131X131 the Right Cylinder?
Choose the SCT when your application needs two or three fixed stopping points from a single compact actuator, avoiding the cost and alignment issues of two separate cylinders. If the 402 N push force per section is marginal, stepping up to the 40 mm bore provides 628 N at the same pressure. For direct replacement, match the 32 mm bore, both 131 mm strokes, PT port thread, and basic mounting configuration.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 131 + 131 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 SCT32X131X131 FAQ
It provides three distinct mechanical stops: fully retracted at 0 mm, mid-extension at 131 mm, and full extension at 262 mm. Because both section strokes are equal, the mid and combined positions are unique.
Yes, if your sequence requires a 131 mm stroke followed by another 131 mm stroke from the same rod line. The SCT tandem design eliminates the need for a second cylinder, mounting bracket, and coupler, saving space and simplifying plumbing.
