About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X155X295S
The SCT32X155X295S is a 32 mm bore multi-position tandem cylinder that delivers four fixed rod positions: 0 mm (fully retracted), 155 mm, 295 mm, and a total extended travel of 450 mm. Each piston section generates 402 N of push force at 0.5 MPa, scaling up to 724 N at the maximum operating pressure of 0.9 MPa, providing reliable actuation for sequenced movements.
This model includes a built-in magnet (-S suffix), enabling direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for non-contact position feedback. The 12 mm diameter rod and M10x1.25 rod thread are standard for the 32 mm bore, and the body length A(SCT) is 233 mm, plus the combined stroke length.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X155X295S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X155X295S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 155 / 295 mm |
| Total travel | 450 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) | 155 mm |
| P2 (section 2) | 295 mm |
| P3 (both extended) | 450 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 SCT32X155X295S Is Used
Four-Position Sorting Gate
Directs packages or parts to four different conveyor lanes by stopping the rod at 0, 155, 295, or 450 mm, each aligning a diverter flap to a specific chute.
Multi-Depth Pressing
Performs a two-stage pressing operation where the first section extends to 155 mm for an initial forming step, and the second section adds 295 mm of travel for a deeper final press at 450 mm.
Sequenced Clamping Fixture
Clamps a workpiece in stages: the rod advances to 295 mm to close a safety gate, then to 450 mm to apply final clamping pressure, with sensor confirmation at each position via the built-in magnet.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X155X295S the Right Cylinder?
Select this cylinder when your application requires four distinct stopping points from a single compact unit, eliminating the complexity of two separate cylinders and external hard stops. If higher force is needed, consider stepping up to the 40 mm bore SCT40 series, which provides 628 N of push force per section at 0.5 MPa. For replacement, ensure the match is an AirTAC SCT with a 32 mm bore, 155 mm and 295 mm strokes, PT port thread, and the -S magnet option.
With a combined stroke of 450 mm, the rod extends significantly; ensure the load is guided externally to prevent side-loading and rod bending, especially when the cylinder is not in a fully retracted or fully extended state.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 155 + 295 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 SCT32X155X295S FAQ
This tandem cylinder provides four discrete mechanical stops. The rod positions are 0 mm (fully retracted), 155 mm (first section extended), 295 mm (second section extended), and 450 mm (both sections extended for total travel).
Yes, in applications requiring a fixed sequence of positions. The SCT32X155X295S integrates two strokes on one common rod line, saving space and simplifying pneumatic circuitry compared to mounting two separate SC32 cylinders back-to-back. It is a direct replacement for another AirTAC SCT32X155X295S unit.
