About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X150X30S
The SCT80X150X30S is an 80 mm bore multi-position tandem cylinder that provides four defined rod positions: 0 mm (fully retracted), 30 mm, 150 mm, and the total travel of 180 mm. Each piston section delivers 2513 N of push force at 0.5 MPa, rising to 4523 N at the maximum operating pressure of 0.9 MPa. The 25 mm diameter rod and PT3/8 ports handle demanding pneumatic sequences.
A built-in magnet is integrated into the piston, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing at any of the four stops. The cylinder body has a 296 mm base length and uses a 28 mm air cushion at each end to manage end-of-stroke deceleration. This genuine AirTAC unit is ideal for sorting gates and multi-step clamping.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X150X30S Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X150X30S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 150 / 30 mm |
| Total travel | 180 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) | 150 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 180 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 SCT80X150X30S Is Used
Sorting Gate Actuator
Uses the four distinct stops to divert packages to different conveyor lanes based on size, controlled by sensor feedback at each position.
Two-Depth Clamping Fixture
Applies a light clamp at the 30 mm position for delicate parts, then advances to the full 180 mm stroke for high-force holding during machining.
Multi-Step Press Feed
Indexes material in two precise increments (30 mm and 150 mm) for a stamping or forming press, ensuring accurate material placement without overfeeding.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X150X30S the Right Cylinder?
Choose the SCT80 series when a single actuator must provide four distinct stopping points, eliminating the cost and complexity of two separate cylinders with external stops. For lighter multi-position tasks, stepping down to the 63 mm bore reduces per-section force to 1559 N at 0.5 MPa. A direct replacement must match the 80 mm bore, both the 150 mm and 30 mm strokes, the PT port thread, and the integrated magnet. With a 150 mm section stroke, ensure the load is guided if side forces are present to protect the rod and bearing.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 150 + 30 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 SCT80X150X30S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (home), 30 mm (first extension), 150 mm (second extension), and 180 mm (full extension of both sections).
The replacement must be a genuine AirTAC SCT80X150X30S. It requires an 80 mm bore, exactly 150 mm and 30 mm section strokes, a built-in magnet for sensors, and PT3/8 threaded ports to ensure identical mounting and pneumatic compatibility.
