About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X280S
The SCT32X50X280S tandem cylinder delivers four discrete rod positions—0 mm, 50 mm, 280 mm, and 330 mm total travel—from a single tie-rod body. Each 32 mm bore section generates 402 N of push force at 0.5 MPa (724 N at 0.9 MPa), making it a compact solution for multi-stop sorting or diverting tasks where space is tight.
The built-in magnet allows CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for end-of-position sensing at each stop. With a 12 mm rod, M10x1.25 rod thread, and PT1/8 ports, this model includes a 21 mm air cushion in each section to manage end-of-travel impact without external shocks.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X280S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 280 mm |
| Total travel | 330 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) | 280 mm |
| P3 (both extended) | 330 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 SCT32X50X280S Is Used
Four-Way Diverter Gate
Uses the four distinct rod positions (0, 50, 280, 330 mm) to direct packages or materials down separate chutes in a conveyor system, simplifying pneumatic logic.
Multi-Depth Press Insertion
Installs bushings or pins to two different controlled depths in a single cycle. The 50 mm stroke sets the first depth, and the 280 mm stroke drives the second, deeper insertion.
Staged Part Ejection
Ejects finished parts from a die in two stages: a 50 mm push to break the part free, followed by a 280 mm sweep to clear the tooling zone, all from one compact actuator.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X280S the Right Cylinder?
Choose the SCT32X50X280S when your process needs four fixed mechanical stops without the complexity of servo controls or two separate cylinders. The unequal strokes (50 mm and 280 mm) provide a short advance for a first position and a longer stroke for a second, combining to a 330 mm full extension. If your load requires more push force, step up to the 40 mm bore SCT, which delivers 628 N per section at 0.5 MPa.
For replacement, match the 32 mm bore, both strokes (50 mm and 280 mm), PT port thread, and the -S magnet option. Since the 280 mm section stroke is substantial, ensure the rod is externally guided or the load is centered to prevent side-loading and premature seal wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 280 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 SCT32X50X280S FAQ
This tandem cylinder provides four discrete positions: fully retracted (0 mm), first section extended (50 mm), second section extended (280 mm), and both sections extended for a total travel of 330 mm. It does not offer infinitely variable positioning.
Yes, it can replace two individual 32mm bore cylinders with 50 mm and 280 mm strokes in a tandem arrangement, provided the mounting is basic, ports are PT, and a magnet is required for sensors. The SCT integrates both strokes into one tie-rod assembly, reducing mounting hardware and alignment effort.
