About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X45S
The SCT50X60X45S is a tandem multi-position cylinder that delivers four discrete rod positions—0 mm (fully retracted), 60 mm, 45 mm, and the combined 105 mm total travel—by pressurising one or both of its 50 mm bore sections. Each actuated section provides a push force of 982 N at 0.5 MPa, rising to 1767 N at the maximum operating pressure of 0.9 MPa, driven through a 20 mm diameter piston rod.
This model includes a built-in magnet (suffix -S), allowing CMSG, DMSG, or EMSG solid-state and reed sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke or mid-position sensing without external brackets. The body length A(SCT) is a compact 243 mm, and the adjustable air cushion at each end absorbs energy to reduce noise and vibration during high-speed cycles.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X45S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X45S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 60 / 45 mm |
| Total travel | 105 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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) | 60 mm |
| P2 (section 2) | 45 mm |
| P3 (both extended) | 105 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 SCT50X60X45S Is Used
Multi-Stop Diverter Gate
Positions a diverter chute to four distinct paths in a conveyor system using the 0, 60, 45, and 105 mm stops, directing product flow without needing multiple actuators.
Two-Depth Pressing Station
Executes a shallow pre-press at the 45 mm position and a full-depth press at 105 mm, with a 60 mm intermediate stop for part ejection, all from a single compact cylinder.
Sequential Part Feeding
Advances parts in a magazine feeder with three distinct push lengths, using the 45 mm, 60 mm, and 105 mm positions to separate and stage components for a pick-and-place.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X45S the Right Cylinder?
Choose the SCT50X60X45S when your process requires four fixed stopping points without the complexity of servo controls or multiple individual cylinders. For applications needing a higher force per section, stepping up to the 63 mm bore SCT63 offers a push force of 1559 N at 0.5 MPa, while a step down to the 40 mm bore provides 628 N if space is constrained. This cylinder is a direct replacement for another AirTAC SCT50 with 60 mm and 45 mm strokes, PT ports, and a magnet, ensuring drop-in compatibility. For strokes over 300 mm, consider external guiding to protect the rod from side loads.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 60 + 45 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 SCT50X60X45S FAQ
This tandem cylinder provides four discrete positions: 0 mm (fully retracted), 60 mm (section one extended), 45 mm (section two extended), and 105 mm (both sections extended, total travel). The stops are fixed by the two stroke lengths and are not infinitely adjustable.
The SCT integrates two piston sections on a single common rod, which saves space and simplifies plumbing compared to two individual cylinders with a coupled rod. It provides the same per-section force (982 N push at 0.5 MPa) as a standard SC50 but achieves multi-position control from one compact, pre-aligned unit.
