About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X50X150S
The SCT80X50X150S is a double-acting multi-position cylinder that delivers four fixed rod positions: 0 mm (fully retracted), 50 mm, 150 mm, and the total travel of 200 mm. Each piston section provides 2513 N of push force at 0.5 MPa, driven by a 25 mm diameter rod through PT3/8 ports. This tandem configuration is ideal for material handling tasks requiring two distinct intermediate stops without the complexity of servo controls.
The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for reliable end-of-stroke or mid-stroke position feedback. With a body length A(SCT) of 296 mm and a 28 mm adjustable air cushion, this genuine AirTAC unit absorbs impact quietly, making it a robust choice for multi-stop feeding or sorting stations.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X50X150S Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X50X150S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 50 / 150 mm |
| Total travel | 200 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| 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, 28 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) | 150 mm |
| P3 (both extended) | 200 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SCT80~100 Multi-Position Tandem Cylinder SCT80X50X150S Is Used
Four-Position Diverter Gate
Routes packages to four separate conveyor lanes by stopping the rod at 0, 50, 150, or 200 mm, using simple pneumatic valves and the cylinder's discrete stops.
Multi-Depth Pressing
Executes two different pressing depths in one cycle. The 50 mm stroke handles a shallow pre-form, while the 150 mm stroke completes a deep draw, all with a single actuator.
Staged Assembly Stop
Positions a component at two distinct workstations along a linear slide. The built-in magnet confirms arrival at the 50 mm and 200 mm positions before the next operation begins.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X50X150S the Right Cylinder?
Choose the SCT80X50X150S when your process needs a compact, purely pneumatic solution for four-position control, eliminating the need for two separate cylinders and their associated mounting hardware. If the 2513 N push force at 0.5 MPa is insufficient for the load, stepping up to the 100 mm bore provides 3927 N per section. For a direct replacement, ensure the substitute matches the 80 mm bore, both 50 mm and 150 mm strokes, PT port thread, basic mounting, and the -S magnet option.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 150 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 SCT80~100 Multi-Position Tandem Cylinder SCT80X50X150S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (home), 50 mm (first section extended), 150 mm (second section extended), and 200 mm (both sections extended). It does not offer infinitely variable positioning.
Yes, it is a direct form-and-function replacement for two individually mounted SC80 cylinders with 50 mm and 150 mm strokes, provided the rod force of 2513 N per section at 0.5 MPa is adequate. The SCT saves space and simplifies the pneumatic circuit by using a single body.
