About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X105X110S
The SCT80X105X110S is a double-acting, multi-position tandem cylinder that provides four fixed rod positions without external hard stops. Its two piston sections give stops at 0 mm (fully retracted), 105 mm, 110 mm, and 215 mm total travel, making it a compact alternative to two separate actuators for two-step positioning tasks.
With an 80 mm bore, each actuated section delivers 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa), driven through a 25 mm diameter piston rod. The integrated magnet allows CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing. The body length A is 296 mm plus strokes, and the integral air cushion is 28 mm per end.

| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 105 / 110 mm |
| Total travel | 215 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) | 105 mm |
| P2 (section 2) | 110 mm |
| P3 (both extended) | 215 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 SCT80X105X110S Is Used
Two-Stage Part Feeding
Extend to 105 mm for a pre-feed position, then to 110 mm for the final placement, giving a controlled two-step advance from a single tandem cylinder.
Clamp & Detect
Use the 105 mm stop for a low-force part contact check, then pressurize the second section to 110 mm for full clamping force before machining.
Dual-Stop Diverter Gate
Position a diverter gate at 105 mm for one chute and 110 mm for a second, with the magnet confirming arrival at each discrete stop via a barrel-mounted sensor.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X105X110S the Right Cylinder?
Choose the SCT80X105X110S when your process needs two distinct extended positions from a single cylinder body, avoiding the complexity of aligning two separate actuators. The 105 mm and 110 mm strokes create closely spaced stops ideal for a two-stage feed or a part-present check followed by a clamp. For higher force, stepping up to the 100 mm bore provides 3927 N of push per section at 0.5 MPa, while the 63 mm bore offers 1559 N if space is tighter.
To replace this unit, match the 80 mm bore, both the 105 mm and 110 mm section strokes, the PT port thread, and the built-in magnet (-S suffix). This model is basic mounting, so confirm the existing bracket type—FA, FB, CA, CB, or LB kits are available if the mounting style needs to change. With a combined stroke of 215 mm, ensure the rod is guided if the load applies significant side force.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 105 + 110 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 SCT80X105X110S FAQ
It provides four discrete mechanical stops: 0 mm (fully retracted), 105 mm (section one extended), 110 mm (section two extended), and 215 mm (both sections extended). The positions are fixed by the two stroke lengths and cannot be adjusted without changing the cylinder.
Yes, if your sequence requires two fixed stroke lengths from a common retracted position. The SCT80X105X110S combines both strokes into one tandem body, eliminating the need to synchronize two separate actuators. Ensure the replacement matches the 80 mm bore, 105 mm and 110 mm strokes, PT ports, and the -S magnet option for sensor compatibility.
