Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X30X30
The AirTAC Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X30X30 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 30mm and 30mm give 3 controllable stop positions across a 60mm total travel, with a Ø80mm bore, PT3/8 ports and adjustable end cushioning.

About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X30X30
The SCT80X30X30 is an 80 mm bore multi-position cylinder that delivers three fixed rod positions: fully retracted (0 mm), 30 mm, and 60 mm total travel. Each piston section generates 2513 N of push force at 0.5 MPa, offering robust power for short-stroke indexing tasks.
Built on a durable tie-rod design with a 25 mm diameter rod and PT3/8 ports, this tandem cylinder uses an adjustable air cushion (28 mm length) for smooth end-of-stroke deceleration. Its body length A(SCT) measures 296 mm, making it a compact solution for applications requiring two distinct extended stops without complex controls.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X30X30 Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X30X30 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 30 / 30 mm |
| Total travel | 60 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 30 mm |
| P2 (both extended) | 60 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 SCT80X30X30 Is Used
Two-Way Diverter Gate
Actuates a flap to three distinct angles for sorting packages onto two different conveyor lines from a single infeed.
Dual-Depth Pressing
Provides a partial advance (30 mm) for pre-compression and a full advance (60 mm) for final forming in a compact assembly press.
Multi-Stop Part Transfer
Shifts a workpiece between a pick point, an inspection station, and a reject chute using the three fixed rod positions.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X30X30 the Right Cylinder?
Choose the SCT80X30X30 when your process needs a simple, pneumatic method to reach two separate extended positions—it eliminates the cost and complexity of two individual cylinders with external stops. For lighter loads, stepping down to a 63 mm bore reduces the per-section push force to 1559 N at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N.
As a direct replacement, this model matches any AirTAC SCT80 with 30 mm strokes on both sections, PT thread ports, and a basic mounting configuration. If your application requires position sensing, specify the -S magnet option to accommodate barrel-mounted sensors.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 30 + 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 SCT80X30X30 FAQ
It provides three discrete mechanical stops: 0 mm (fully retracted), 30 mm (first section extended), and 60 mm (both sections extended). The positions are fixed by the two 30 mm strokes.
While two cylinders can achieve similar strokes, the SCT80X30X30 integrates both piston sections on a single common rod, guaranteeing coaxial alignment and reducing the overall footprint. It also simplifies pneumatic control for sequenced multi-position moves.
