About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X463X119
The SCT80X463X119 is a double-acting multi-position pneumatic cylinder that delivers four fixed rod positions: fully retracted (0 mm), 119 mm, 463 mm, and the total extended travel of 582 mm. Each 80 mm bore section generates a push force of 2513 N at 0.5 MPa, rising to 4523 N at the maximum operating pressure of 0.9 MPa, driven through a 25 mm diameter rod.
Built on a robust tie-rod design with a 296 mm body length, this tandem cylinder integrates adjustable end cushioning for smooth deceleration at each stop. The PT3/8 ports and M20x1.5 rod thread provide standard connectivity, making this unit a direct fit for machinery requiring sequenced, multi-stop linear motion without complex servo controls.

| 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) | 463 mm |
| P2 (section 2) | 119 mm |
| P3 (both extended) | 582 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 SCT80X463X119 Is Used
Two-Stage Diverter Gate
Positions a diverter chute at a retracted home, a partial 119 mm opening for one lane, and a full 463 mm or 582 mm extension to reach a second or third conveyor lane, directing product flow in a packaging line.
Sequential Clamping Fixture
Executes a two-step clamping sequence: a rapid 463 mm advance to close on a large part, followed by a controlled 119 mm stroke for final high-force clamping, with the 0 mm position releasing the finished workpiece.
Multi-Depth Assembly Press
Provides three distinct pressing depths in an assembly station. The rod stops at 119 mm for an initial insertion, 463 mm for a secondary press-fit, and the full 582 mm for a final forming operation, all from one compact cylinder.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X463X119 the Right Cylinder?
Selecting this SCT model is ideal when an application requires two distinct extended positions that are significantly far apart, such as a 463 mm primary stroke and a 119 mm secondary stroke, which is difficult to achieve reliably with a single cylinder and external hard stops. If a higher force is needed, stepping up to the 100 mm bore provides 3927 N of push per section at 0.5 MPa, while the 63 mm bore offers a more compact alternative at 1559 N.
For direct replacement, match the 80 mm bore, both the 463 mm and 119 mm strokes, PT port thread, and basic mounting configuration. As the primary stroke exceeds 300 mm, ensure the rod is adequately guided or supported to prevent side-loading and bending, especially when the cylinder is fully extended to its 582 mm total length.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 463 + 119 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 SCT80X463X119 FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 119 mm, 463 mm, and 582 mm (fully extended). The positions are achieved by pressurizing the first section, the second section, or both simultaneously. It does not offer infinitely variable positioning.
The force is generated per actuated piston section, not combined. Each 80 mm bore section provides a push force of 2513 N at 0.5 MPa and a pull force of 2268 N. The force is the same whether you are moving to the 119 mm, 463 mm, or 582 mm position, assuming the same number of sections are pressurized.
