About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X130X131
The SCT32X130X131 is a double-acting multi-position cylinder that delivers four distinct rod positions by combining two piston sections on a single axis. With strokes of 130 mm and 131 mm, the achievable stops are 0 mm (fully retracted), 130 mm, 131 mm, and the total travel of 261 mm, offering fine positional control for light-duty sequencing tasks.
Each 32 mm bore section generates 402 N of push force at 0.5 MPa, rising to 724 N at the maximum operating pressure of 0.9 MPa. The cylinder uses a 12 mm diameter piston rod, PT1/8 ports, and an M10x1.25 rod thread. Its tie-rod construction includes a 21 mm adjustable air cushion and a body length A of 233 mm.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X130X131 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 130 / 131 mm |
| Total travel | 261 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) | 130 mm |
| P2 (section 2) | 131 mm |
| P3 (both extended) | 261 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 SCT32X130X131 Is Used
Two-Stage Diverter Gate
Controls a gate with a closed, partial-open, and two full-open paths, using the 130 mm and 131 mm strokes to align with different conveyor lanes.
Multi-Depth Light Pressing
Provides two distinct pressing depths (130 mm and 131 mm) plus a 261 mm total stroke for part ejection in a small assembly fixture.
Sequential Part Staging
Positions a component at 130 mm for adhesive application, 131 mm for UV curing, and 261 mm for pick-off, all from one compact tandem unit.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X130X131 the Right Cylinder?
This four-position configuration is ideal when an application requires two closely spaced intermediate stops alongside the home and full-extend positions, eliminating the need for two separate cylinders and external hard stops. If higher force is needed, stepping up to the 40 mm bore SCT provides 628 N of push per section at the same 0.5 MPa pressure. For direct replacement, match the 32 mm bore, the exact strokes of 130 mm and 131 mm, PT port thread, and basic mounting. Since the stroke exceeds 100 mm, ensure the rod is adequately guided if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 130 + 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 SCT32X130X131 FAQ
It provides 4 discrete mechanical stops: 0 mm (fully retracted), 130 mm, 131 mm, and the combined total travel of 261 mm. The positions are selected by pressurizing either piston section individually or both together.
No, like all standard pneumatic cylinders, it will not hold a load if pressure is lost or the valve is centered. If a load must be locked at the 130 mm or 131 mm stop without live pressure, an external rod brake or pilot-operated check valve is required.
