About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X10X150S
The SCT80X10X150S is a tie-rod multi-position cylinder that delivers four fixed rod positions from two independent piston sections on a common rod line. With strokes of 10 mm and 150 mm, the reachable stops are 0 mm (fully retracted), 10 mm, 150 mm, and the combined total travel of 160 mm, selected by pressurising either section or both.
Each 80 mm bore section generates 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, using a 25 mm diameter rod. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors on the barrel for position feedback, while the 28 mm adjustable air cushion at each end decelerates the load smoothly.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X10X150S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 10 / 150 mm |
| Total travel | 160 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) | 10 mm |
| P2 (section 2) | 150 mm |
| P3 (both extended) | 160 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 SCT80X10X150S Is Used
Two-Stage Sorting Gate
Uses the 10 mm stop for a partial-open reject position and the 150 mm stop for full pass-through, directing parts down different chutes from one actuator.
Dual-Depth Pressing
Provides a light-contact 10 mm advance for positioning a delicate workpiece, followed by a full 150 mm power stroke for the forming or insertion operation.
Multi-Stop Feeding
Advances a pusher bar to an intermediate 10 mm staging point before completing the 150 mm feed, synchronising with two separate conveyor lanes.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X10X150S the Right Cylinder?
This four-position tandem unit replaces setups that would otherwise need two separate cylinders and external hard stops to achieve the same discrete positioning. When the application demands higher force, stepping up to the 100 mm bore provides 3927 N of push per section at 0.5 MPa. For a drop-in replacement, match the 80 mm bore, both the 10 mm and 150 mm section strokes, the PT port thread, and the -S magnet suffix; the basic mounting style means no additional brackets are included.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 10 + 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 SCT80X10X150S FAQ
It provides four distinct rod positions: 0 mm (fully retracted), 10 mm (first section extended), 150 mm (second section extended), and 160 mm (both sections extended). The stops are fixed by the two stroke lengths.
Each of the two piston sections in the 80 mm bore produces 2513 N of push force and 2268 N of pull force when operated at 0.5 MPa air pressure. The force does not double when both sections are pressurised for the 160 mm position.
