Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X150X150S
The AirTAC Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X150X150S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 150mm and 150mm give 3 controllable stop positions across a 300mm total travel, with a Ø100mm bore, PT1/2 ports and adjustable end cushioning.

About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X150X150S
The SCT100X150X150S tandem cylinder delivers three fixed rod positions: fully retracted, 150 mm, and 300 mm total travel. Each piston section generates 3927 N of push force at 0.5 MPa, making it suitable for heavy-duty sorting or clamping tasks that need repeatable stops without complex controls.
The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors along the 308 mm tie-rod body for end-of-stroke detection. A 25 mm diameter rod and M20x1.5 rod thread handle high side loads, while the 29 mm air cushion at each end decelerates the mass smoothly.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X150X150S Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X150X150S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 150 / 150 mm |
| Total travel | 300 mm |
| Stop positions | 3 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/2 |
| 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, 29 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) | 150 mm |
| P2 (both extended) | 300 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SCT100X150X150S Is Used
3-Position Sorting Gate
Diverts packages to three lanes using the 0, 150, and 300 mm stops, ideal for conveyor systems with sensor feedback.
Two-Depth Press Operation
Provides a partial advance at 150 mm and full closure at 300 mm for two-stage pressing or forming applications.
Heavy Panel Indexing
Indexes large sheets or panels to three precise locations for drilling or fastening, using the high force capacity.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X150X150S the Right Cylinder?
Choose the SCT100X150X150S when you need three defined positions from a single cylinder body instead of complex multi-actuator setups. If 3927 N per section is more thrust than needed, the 80 mm bore SCT provides 2513 N push at the same pressure. For replacement, match the 100 mm bore, both 150 mm strokes, PT ports, and the -S magnet option. At 300 mm total stroke, ensure the rod is guided if side forces are present.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 150 + 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 SCT100X150X150S FAQ
Three discrete rod positions: 0 mm (retracted), 150 mm (first section extended), and 300 mm (both sections extended). The two equal strokes create three stops.
Yes, if the original is an AirTAC SCT with 100 mm bore, 150 mm stroke on both sections, PT ports, and a magnet. Verify the mounting style, as this is a basic body without brackets.
