Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X200X175
The AirTAC Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X200X175 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 200mm and 175mm give 4 controllable stop positions across a 375mm total travel, with a Ø80mm bore, PT3/8 ports and adjustable end cushioning.

About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X200X175
The SCT80X200X175 is an 80 mm bore tandem multi-position cylinder that delivers four fixed rod positions: fully retracted (0 mm), 175 mm, 200 mm, and the combined total travel of 375 mm. Each piston section generates 2513 N of push force at 0.5 MPa, scaling to 4523 N at the maximum operating pressure of 0.9 MPa, driven through a robust 25 mm diameter piston rod.
This tie-rod cylinder uses PT3/8 ports and integrates a 28 mm adjustable pneumatic cushion in each section to decelerate the load smoothly at every stop. The body length A(SCT) is 296 mm, providing a compact tandem footprint for sequencing tasks that require two distinct mid-stroke positions without the complexity of external hard stops.

| Total travel | 375 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 |

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) | 200 mm |
| P2 (section 2) | 175 mm |
| P3 (both extended) | 375 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 SCT80X200X175 Is Used
Two-Stage Diverter Gate
Operates a conveyor diverter with a retracted home, a 175 mm partial-open for sorting to lane one, and a 200 mm full-open for lane two, with a 375 mm service position for clearing jams.
Multi-Depth Clamping Fixture
Provides three clamping depths for different part families on a machining centre: a light-touch position at 175 mm, a medium-grip at 200 mm, and a full-power clamp at 375 mm extension.
Sequential Part Ejection
Ejects parts from a die in a two-step sequence: a 175 mm stroke pushes the part clear of the tool, and a subsequent 200 mm stroke moves it fully onto an outfeed chute, preventing part collisions.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X200X175 the Right Cylinder?
Select the SCT80X200X175 when a pneumatic sequence needs two intermediate stopping points—here at 175 mm and 200 mm—on the way to a 375 mm full extension. This tandem unit is far simpler than plumbing two separate 80 mm bore cylinders with external stop valves and brackets. If the 2513 N per-section push force at 0.5 MPa is more than required, stepping down to a 63 mm bore (1559 N push) can reduce air consumption while still providing four positions.
For replacement, match the 80 mm bore, both strokes (200 mm and 175 mm), PT port thread, and basic mounting configuration exactly. With a 200 mm section stroke, ensure the rod is guided if the load applies significant side force, as the 25 mm rod may deflect under off-axis loads at full extension.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 200 + 175 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 SCT80X200X175 FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 175 mm (first section extended), 200 mm (second section extended), and 375 mm (both sections extended). The positions are fixed by the two stroke lengths and are not infinitely adjustable.
The force is generated per actuated piston section, not combined. Each 80 mm section provides 2513 N of push force at 0.5 MPa. Pressurizing one section extends the rod to its stroke; pressurizing both extends it to the total travel, but the push force on the load remains the single-section value of 2513 N at that pressure.
