About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X30S
The SCT32X30X30S is a double-acting multi-position tandem cylinder that delivers three fixed rod positions: fully retracted (0 mm), 30 mm, and 60 mm total travel. By pressurising either or both of its two piston sections, you get repeatable mechanical stops without external hardware. Each 32 mm bore section provides a push force of 402 N at 0.5 MPa, making it suitable for light sorting and diverting tasks.
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for end-of-stroke or mid-position confirmation. The 12 mm diameter rod and M10x1.25 rod thread handle small payloads, while the 21 mm adjustable air cushion at each end decelerates the load smoothly. The body length A(SCT) is 233 mm, providing a compact envelope for tight automation cells.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X30S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X30S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 30 / 30 mm |
| Total travel | 60 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) | 30 mm |
| P2 (both extended) | 60 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 SCT32X30X30S Is Used
3-Position Diverter Gate
Use the three discrete stops (0, 30, 60 mm) to route small packages or components down two different lanes on a conveyor, with the middle position acting as a bypass.
Two-Depth Pressing
Achieve two distinct pressing depths in a light assembly fixture. The first section extends 30 mm for a pre-insertion step, and both sections extend to 60 mm for the final press.
Multi-Stop Part Feeding
Control a stop gate in a feeder bowl track. Retract to let one part pass, extend 30 mm to stop the first part, or extend fully to 60 mm to isolate and hold back two parts.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X30S the Right Cylinder?
Choose the SCT when your application needs two or three distinct stopping points from a single pneumatic axis, eliminating the cost and complexity of two separate cylinders with external stops. For this 32 mm bore, if you need higher force, step up to the SCT40 series, which delivers 628 N of push per section at 0.5 MPa. Ensure the replacement matches the bore, both 30 mm strokes, PT port thread, basic mounting, and the -S magnet option.
Since the total travel is only 60 mm, rod deflection is minimal, but always align the load axially to prevent side-loading the 12 mm rod and ensure full cushion life.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 30 + 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 SCT32X30X30S FAQ
It provides three distinct mechanical stop positions: 0 mm (fully retracted), 30 mm (first section extended), and 60 mm (both sections extended for total travel). The two equal strokes create a 3-position sequence.
Yes, if your sequence requires exactly the 0, 30, and 60 mm stops. The SCT32X30X30S integrates two piston sections on one rod line, saving space and eliminating the need to synchronise two separate cylinders. Ensure the per-section force of 402 N at 0.5 MPa meets your load requirements at each stop.
