Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X60X30S
The AirTAC Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X60X30S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 60mm and 30mm give 4 controllable stop positions across a 90mm total travel, with a Ø80mm bore, PT3/8 ports and adjustable end cushioning.

About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X60X30S
The SCT80X60X30S is an 80 mm bore tandem multi-position cylinder that provides four fixed rod positions: 0 mm (fully retracted), 30 mm, 60 mm, and the total travel of 90 mm. By pressurising the two piston sections independently or together, you get repeatable mechanical stops without external hard stops or complex controls. Each section delivers 2513 N of push force at 0.5 MPa, rising to 4523 N at 0.9 MPa, driven through a 25 mm diameter rod.
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 intermediate position sensing. The cylinder body has a length A of 296 mm and uses adjustable pneumatic cushioning with a 28 mm cushion length to manage end-of-stroke deceleration. It is a genuine AirTAC component built for sequenced material handling tasks.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X60X30S Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X60X30S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 60 / 30 mm |
| Total travel | 90 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) | 60 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 90 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 SCT80X60X30S Is Used
Two-Way Diverter Gate
Use the four positions to direct parts into three separate lanes. Retract to lane 1, extend to 30 mm for lane 2, 60 mm for lane 3, and full 90 mm extension for a reject chute.
Multi-Level Part Staging
Stage components at three different heights for a pick-and-place sequence. The 30 mm and 60 mm stops provide intermediate presentation levels, while 90 mm clears the nest entirely.
Sequential Clamping & Forming
Apply a light clamp at 30 mm extension, a forming pressure at 60 mm, and a full ejection stroke at 90 mm. The discrete stops ensure process consistency without operator adjustment.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X60X30S the Right Cylinder?
Choose the SCT80X60X30S when your application needs four distinct mechanical stop positions within a compact 90 mm total stroke, eliminating the complexity of two separate cylinders and their mounting brackets. If higher force is needed, stepping up to the 100 mm bore SCT100 provides 3927 N of push per section at 0.5 MPa. For a direct replacement, match the 80 mm bore, both strokes of 60 mm and 30 mm, PT port thread, basic mounting, and the -S magnet option.
With a total travel of 90 mm, rod bending is not a primary concern, but ensure the load is guided if significant side forces are present. The built-in magnet simplifies adding position feedback at any of the four discrete stops.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 60 + 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 SCT80~100 Multi-Position Tandem Cylinder SCT80X60X30S FAQ
It provides four discrete mechanical stop positions: 0 mm (fully retracted), 30 mm, 60 mm, and 90 mm (full extension). These are achieved by pressurising the 30 mm section, the 60 mm section, or both sections together.
Yes. The -S suffix means this cylinder has a built-in magnet, making it directly compatible with AirTAC CMSG, DMSG, and EMSG series reed and solid-state sensors. The sensors clamp onto the cylinder's tie-rods to detect piston position at any of the four stops.
