About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X50X100S
The SCT100X50X100S is a tandem multi-position pneumatic cylinder that provides four fixed rod positions: fully retracted (0 mm), 50 mm, 100 mm, and the total extended travel of 150 mm. Each of its two 100 mm bore piston sections generates a push force of 3927 N at 0.5 MPa, making it suitable for heavy-duty material handling tasks where intermediate stops are required without complex servo controls.
This model includes a built-in magnet (suffix -S), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for reliable end-of-stroke and intermediate position detection. The cylinder features a 25 mm diameter rod, M20x1.5 rod thread, PT1/2 ports, and a 29 mm adjustable air cushion, with a body length A(SCT) of 308 mm.

| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 50 / 100 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) | 50 mm |
| P2 (section 2) | 100 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 SCT100X50X100S Is Used
Four-Position Sorting Gate
Directs packages or pallets to four separate conveyor lanes by stopping the cylinder rod at 0, 50, 100, or 150 mm, each corresponding to a different diverter arm angle.
Multi-Depth Pressing
Controls a press platen to two distinct working depths (50 mm and 100 mm) plus a full-extension 150 mm position for part ejection, all from one pneumatic circuit.
Staged Clamping Fixture
Applies a light clamp at the 50 mm position and full clamping force at 100 mm or 150 mm, protecting delicate workpieces during the initial alignment phase.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X50X100S the Right Cylinder?
Choose the SCT100X50X100S when your application needs four distinct mechanical stop points from a single compact assembly, eliminating the cost and complexity of two separate cylinders and external hard stops. If your force requirement is lower, stepping down to the 80 mm bore SCT80X50X100 provides 2513 N of push force per section at 0.5 MPa, which may reduce air consumption and physical footprint.
For direct replacement, match the 100 mm bore, both stroke lengths (50 mm and 100 mm), PT port thread, and the -S magnet option. This cylinder uses a basic mount; if a pivoting or flange mount is needed, confirm that FA, FB, CA, CB, or LB accessories are ordered separately. With a 100 mm stroke on the second section, ensure the guided load is aligned to prevent excessive side-loading on the 25 mm rod.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 100 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 SCT100X50X100S FAQ
This cylinder provides 4 discrete mechanical stop positions: 0 mm (fully retracted), 50 mm (first section extended), 100 mm (second section extended), and 150 mm (both sections extended). The positions are selected by pressurizing the appropriate cylinder ports.
Yes, if your sequence requires fixed 50 mm and 100 mm strokes from a common rod axis. The SCT100X50X100S combines these into one tandem body, saving space and eliminating the need to synchronize two separate cylinders. Ensure the per-section force (3927 N push at 0.5 MPa) meets your load requirements for each actuation phase.
