About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X250S
The SCT32X50X250S is a double-acting multi-position tandem cylinder that provides four fixed rod positions: 0 mm (fully retracted), 50 mm, 250 mm, and the total travel of 300 mm. Each 32 mm bore section delivers a push force of 402 N at 0.5 MPa, making it suitable for light-duty sorting and diverting tasks where multiple precise stops are required without complex controls.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position feedback. The 12 mm diameter rod, PT1/8 ports, and 21 mm adjustable air cushion on each end cap ensure reliable cycling. The body length A(SCT) is 233 mm plus the combined stroke, keeping the assembly compact for its 300 mm total travel.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X250S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X250S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 250 mm |
| Total travel | 300 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) | 50 mm |
| P2 (section 2) | 250 mm |
| P3 (both extended) | 300 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 SCT32X50X250S Is Used
3-Way Diverter Gate
Uses the 50 mm and 250 mm stops to direct packages to three separate conveyor lanes from a single infeed point.
Two-Depth Insertion
The 50 mm and 300 mm positions allow a pick-and-place unit to insert components at a shallow and a deep station in one cycle.
Multi-Stop Clamping
Provides three clamping positions for different workpiece thicknesses, with sensor confirmation at each stop via the built-in magnet.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X250S the Right Cylinder?
Choose the SCT tandem cylinder when a single actuator must reach three or four discrete positions, eliminating the cost and complexity of two separate cylinders with external stops. For this 32 mm bore, if higher force is needed, stepping up to the 40 mm bore provides 628 N of push per section at 0.5 MPa. A direct replacement must match the 32 mm bore, both strokes (50 mm and 250 mm), PT port thread, and the built-in magnet. The 250 mm section stroke is long enough that guiding the rod or supporting the payload is recommended to prevent side-loading and bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 250 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 SCT32X50X250S FAQ
It provides four distinct rod positions: 0 mm (retracted), 50 mm, 250 mm, and 300 mm (total travel). These are achieved by pressurizing the front section, rear section, or both simultaneously.
Yes, if you need the specific 50 mm and 250 mm strokes. It replaces two SC32 cylinders and external stop hardware with a single, compact tandem unit. The replacement must be an AirTAC SCT32X50X250S with the -S magnet option to match sensor functionality.
