About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X15X30S
The SCT80X15X30S is a double-acting multi-position cylinder that delivers four fixed rod positions: 0 mm (fully retracted), 15 mm, 30 mm, and 45 mm (total travel). Each of its two piston sections generates 2513 N of push force at 0.5 MPa, rising to 4523 N at the maximum operating pressure of 0.9 MPa, making it a compact solution for short-throw, multi-stop tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the 80 mm bore tie-rod barrel for non-contact position sensing. The 25 mm diameter piston rod, PT3/8 ports, and 28 mm adjustable air cushion at each end ensure reliable cycling and precise end-of-stroke deceleration.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X15X30S Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X15X30S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 15 / 30 mm |
| Total travel | 45 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) | 15 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 45 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 SCT80X15X30S Is Used
Multi-Level Sorting Gate
Uses the four discrete positions to divert small parts into three separate lanes on a conveyor, with the fully retracted position acting as a bypass.
Two-Depth Pressing
Provides two distinct pressing depths (15 mm and 45 mm) for assembling components with different insertion requirements in a single station.
Short-Stroke Label Applicator
The 15 mm and 30 mm steps position a tamp pad at precise peel and apply heights for high-speed product labeling.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X15X30S the Right Cylinder?
Choose the SCT80X15X30S when your application needs four discrete mechanical stops in a short 45 mm working envelope, eliminating the complexity of two separate cylinders and external hard stops. If you require higher force per section, stepping up to the 100 mm bore provides 3927 N of push at 0.5 MPa. For a direct replacement, match the 80 mm bore, both 15 mm and 30 mm strokes, PT port thread, basic mounting, and the integrated magnet (-S). As the total stroke is short, rod bending is not a concern, but ensure the load is guided if side forces are present.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 15 + 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 SCT80X15X30S FAQ
This tandem cylinder provides four discrete rod positions: 0 mm (fully retracted), 15 mm, 30 mm, and the full extension of 45 mm. These are achieved by pressurizing the first section, the second section, or both simultaneously.
Yes, it is a direct replacement for a two-cylinder setup that previously achieved 15 mm and 45 mm strokes. It saves space and simplifies plumbing. Ensure the replacement matches the 80 mm bore, 15 mm and 30 mm strokes, PT ports, basic mount, and the -S magnet option for sensor compatibility.
