About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X60X150
The SCT80X60X150 tandem cylinder provides four fixed rod positions for sequenced pneumatic operations without external stops. With a 60 mm first-stage stroke and a 150 mm second-stage stroke, the rod can be precisely located at 0, 60, 150, or the full 210 mm extension. Each 80 mm bore piston section generates 2513 N of push force at 0.5 MPa, rising to 4523 N at the 0.9 MPa maximum operating pressure.
This tie-rod cylinder uses a 25 mm diameter rod with M20x1.5 threads and PT3/8 ports. The adjustable air cushion at each end has a 28 mm length to decelerate the piston smoothly. The body length A(SCT) is 296 mm. Standard TPU seals give an operating range of -20 to +70 °C.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X60X150 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 60 / 150 mm |
| Total travel | 210 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) | 60 mm |
| P2 (section 2) | 150 mm |
| P3 (both extended) | 210 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 SCT80X60X150 Is Used
Two-Stage Sorting Gate
Diverts packages to one of three lanes by stopping the rod at 60 mm, 150 mm, or full 210 mm extension, directing items based on size or destination.
Multi-Depth Pressing
Operates a press tool to two different insertion depths. The first stage at 60 mm sets a component, and the second stage at 150 mm completes a full-depth press.
Sequential Part Feeding
Advances parts on a conveyor in controlled steps. A 60 mm stroke indexes the part, and a further 150 mm stroke moves it to the next processing station.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X60X150 the Right Cylinder?
Select the SCT80X60X150 when an application needs four discrete linear positions from a single, compact actuator, avoiding the complexity and plumbing of two separate cylinders with external hard stops. If the 2513 N per-section push force at 0.5 MPa is more than required, stepping down to a 63 mm bore reduces the push force to 1559 N per section. For a direct replacement, match the 80 mm bore, both the 60 mm and 150 mm strokes, PT port thread, and basic mounting. Since the combined stroke exceeds 300 mm, ensure the rod is adequately guided if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 60 + 150 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 SCT80X60X150 FAQ
This cylinder has 4 discrete stop positions because the two strokes are different lengths. The rod can be positioned at 0 mm (fully retracted), 60 mm, 150 mm, and 210 mm (fully extended).
Yes, if the required strokes are exactly 60 mm and 150 mm. The SCT integrates both strokes into a single tandem body, saving space and simplifying the pneumatic circuit. Ensure the replacement matches the PT port thread and basic mounting configuration.
