About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X140X10S
The SCT100X140X10S is a 100 mm bore multi-position tandem cylinder that delivers four discrete rod stops: 0 mm (fully retracted),10 mm,140 mm, and the full150 mm extension. Each piston section generates a push force of 3927 N at0.5 MPa, rising to7068 N at the maximum operating pressure of0.9 MPa, driven through a robust25 mm diameter rod.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for non-contact position sensing. The cylinder body has an A-length of308 mm, features an adjustable pneumatic cushion of29 mm, and uses standard PT1/2 ports. It is a genuine AirTAC component built for sequenced, multi-stop linear tasks.

| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 140 / 10 mm |
| Total travel | 150 mm |
| 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) | 140 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 150 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 SCT100X140X10S Is Used
Two-Depth Pressing
Actuates a press tool to a light contact position at10 mm for alignment, then drives to the full150 mm depth for the forming operation, with sensor confirmation at each stop via the built-in magnet.
Sorting Gate with Bypass
Controls a diverter gate with a home position, a10 mm bypass gap, a140 mm main lane position, and a150 mm flush position, all managed by one compact tandem cylinder.
Staged Clamping Fixture
Provides an initial140 mm rapid advance to a workpiece, followed by a final10 mm high-force clamping stroke, using the magnet to verify the clamp is fully engaged.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X140X10S the Right Cylinder?
Choose the SCT100X140X10S when your process requires two distinct short and long advance positions without the complexity of two separate actuators and external stops. The four defined positions (0,10,140,150 mm) are ideal for a primary long stroke with a precise secondary short step. If the force requirement is lower, stepping down to an80 mm bore reduces the per-section push to2513 N at0.5 MPa, which can lower air consumption and cost.
For replacement, match the100 mm bore, both the140 mm and10 mm section strokes, PT port thread, basic mounting, and the -S magnet option. Since the140 mm stroke section is under300 mm, side-load and rod bending are typically not primary concerns, but always ensure the load is guided if off-axis forces are present.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 140 + 10 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 SCT100X140X10S FAQ
It provides four distinct mechanical stops:0 mm (home),10 mm,140 mm, and150 mm (full extension). These are achieved by pressurising the two piston sections individually or together.
The force is generated per single piston section. At0.5 MPa, one section provides3927 N of push force and3681 N of pull force. The force does not double when both sections are pressurised for a multi-position move.
