About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X160X240S
The SCT100X160X240S is a 100 mm bore tandem multi-position cylinder that delivers four fixed rod positions: fully retracted (0 mm), 160 mm, 240 mm, and the combined total travel of 400 mm. Each piston section generates a push force of 3927 N at 0.5 MPa, scaling up to 7068 N at the maximum operating pressure of 0.9 MPa, driven through a rigid 25 mm diameter rod.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position feedback. The cylinder body has a base length of 308 mm, uses a 29 mm air cushion for smooth deceleration, and connects via standard PT1/2 ports. It is a genuine AirTAC unit built for sequenced pneumatic tasks requiring defined intermediate stops without external hard stops.

| Stop positions | 4 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 (4)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 160 mm |
| P2 (section 2) | 240 mm |
| P3 (both extended) | 400 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 SCT100X160X240S Is Used
Four-Position Diverter Gate
Actuates a conveyor diverter to four precise locations, sorting packages to 0 mm (main line), 160 mm (reject), 240 mm (inspection), and 400 mm (alternate lane) using simple pneumatic controls.
Multi-Depth Pressing Station
Provides two intermediate pressing depths at 160 mm and 240 mm before reaching the full 400 mm stroke, ideal for progressive forming or assembly operations requiring controlled force at each step.
Staged Clamping Fixture
Positions a clamp at 160 mm for part loading, 240 mm for low-force pre-clamping, and 400 mm for full hydraulic-pneumatic clamping force, with sensor confirmation at every stage via the built-in magnet.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X160X240S the Right Cylinder?
Select the SCT100X160X240S when your process needs four distinct linear positions from a single compact assembly, avoiding the complexity and plumbing of two separate cylinders with external stops. For lighter loads, stepping down to an 80 mm bore reduces the per-section push force to 2513 N at 0.5 MPa, while this 100 mm bore provides the higher thrust needed for heavier tooling. To ensure a direct drop-in replacement, match the 100 mm bore, both stroke lengths (160 mm and 240 mm), the PT port thread, and the integrated magnet (-S suffix). Given the combined 400 mm total travel, evaluate the application for side-loads and consider an external guide or rod support if the load is not purely axial.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 160 + 240 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 SCT100X160X240S FAQ
This tandem cylinder provides four discrete stop positions: 0 mm (fully retracted), 160 mm (section one extended), 240 mm (section two extended), and 400 mm (both sections extended). The positions are fixed by the two stroke lengths and are selected by pressurizing the cylinder's sections individually or together.
Yes, it can replace a dual-cylinder setup for sequenced two-axis or two-position movements, provided the strokes match 160 mm and 240 mm. The replacement must be another AirTAC SCT with a 100 mm bore, identical stroke pair, PT1/2 ports, and the -S magnet option to ensure sensor compatibility.
