About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X130X220S
The SCT80X130X220S is a double-acting tandem cylinder that delivers four fixed rod positions—0 mm, 130 mm, 220 mm, and the combined 350 mm total travel—from two independently controlled piston sections on a single rod line. Each section generates 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa), driven through a 25 mm diameter rod and PT3/8 ports.
This model includes a built-in magnet (suffix -S), allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position feedback. The cylinder body has an A-length of 296 mm and uses an adjustable pneumatic cushion of 28 mm to decelerate the load smoothly at each stroke end.

| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 130 / 220 mm |
| Total travel | 350 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) | 130 mm |
| P2 (section 2) | 220 mm |
| P3 (both extended) | 350 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 SCT80X130X220S Is Used
Two-Stage Diverter Gate
Operates a conveyor diverter with a partial-open position at 130 mm for sorting small items and a full-open position at 350 mm for larger packages, all from one compact actuator.
Multi-Depth Pressing
Provides two distinct pressing depths in a light assembly fixture—a 130 mm approach stroke for pre-clamping and a 350 mm total stroke for final insertion, with a retracted safe position.
Sequential Part Feeding
Advances a magazine-fed part through three positions: a 130 mm first-stage push to separate the component, a 220 mm second-stage transfer, and a full 350 mm stroke to load it into the nest.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X130X220S the Right Cylinder?
Choose the SCT80X130X220S when your application needs four precise, repeatable stop points without the complexity of servo control or the bulk of two separate cylinders. The discrete 130 mm and 220 mm strokes are ideal for a two-step feeding or sorting station. If you need higher force, stepping up to the 100 mm bore provides 3927 N of push per section at 0.5 MPa; for a lighter, more compact solution, the 63 mm bore delivers 1559 N per section.
For direct replacement, match the 80 mm bore, both 130 mm and 220 mm section strokes, PT port thread, basic mounting, and the -S magnet option. Because the combined stroke reaches 350 mm, ensure the rod is adequately guided if significant side loads are present to prevent rod bending or premature seal wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 130 + 220 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 SCT80X130X220S FAQ
This tandem cylinder provides four discrete rod positions: fully retracted (0 mm), first section extended (130 mm), second section extended (220 mm), and both sections extended for the total travel (350 mm). You select the position by pressurizing the appropriate combination of the two cylinder sections.
Yes, it is a direct form-fit replacement for a specific tandem setup. To be compatible, the replacement must be an AirTAC SCT with an 80 mm bore, 130 mm and 220 mm section strokes, PT ports, basic mounting, and the -S magnet option. This single-body solution eliminates the alignment and plumbing complexity of two separate actuators.
