About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X140X30
The SCT32X140X30 is a double-acting multi-position cylinder that delivers four fixed rod positions: 0 mm (fully retracted), 30 mm, 140 mm, and 170 mm (total travel). Each piston section, built on a 32 mm bore with a 12 mm rod, generates 402 N of push force at 0.5 MPa, scaling up to 724 N at the maximum operating pressure of 0.9 MPa.
This tandem configuration uses two strokes of different lengths to create an asymmetric positioning sequence without external stops or complex controls. The body length A(SCT) is 233 mm, and the integrated adjustable air cushion on both sections, with a 21 mm cushion length, ensures smooth deceleration at each end-of-stroke position.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X140X30 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 140 / 30 mm |
| Total travel | 170 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) | 140 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 170 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 SCT32X140X30 Is Used
Two-Stage Diverter Gate
Operates a packaging line diverter with a partial-open position at 30 mm for small cartons and a full-open position at 140 mm or 170 mm for large totes, all from one compact actuator.
Multi-Depth Pressing
Provides a shallow 30 mm press stroke for delicate insertion, a deeper 140 mm stroke for standard forming, and a full 170 mm travel for ejection, controlled by pressurizing each section individually or together.
Selective Part Staging
Stages components at two precise locations along a transfer line, stopping at 30 mm for inspection and 140 mm for a subsequent pick-and-place operation, improving cycle time over single-position cylinders.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X140X30 the Right Cylinder?
Choose the SCT32X140X30 when your process needs four distinct linear positions from a single pneumatic circuit, eliminating the cost and complexity of two separate cylinders and a coupling. If the 402 N push force per section is marginal for your load, stepping up to the 40 mm bore provides 628 N at the same 0.5 MPa. For direct replacement, match the 32 mm bore, both the 140 mm and 30 mm strokes, PT port thread, and basic mounting. If integrating a sensor for position confirmation, specify the -S magnet option.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 140 + 30 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 SCT32X140X30 FAQ
This tandem cylinder has four discrete rod positions: 0 mm (fully retracted), 30 mm (stroke of section two), 140 mm (stroke of section one), and 170 mm (both sections extended). The positions are fixed by the two stroke lengths and selected by pressurizing the appropriate air ports.
The SCT integrates two piston sections on a single common rod, saving mounting space and eliminating the need for external alignment and coupling hardware. It provides the same per-section force (402 N push at 0.5 MPa) as a standard SC32 cylinder but delivers three or four fixed stops from one compact unit.
