About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X300X50SH
The AirTAC SCT80X300X50SH is a tie-rod tandem cylinder engineered to deliver four distinct mechanical stop positions—0 mm, 50 mm, 300 mm, and the full 350 mm total travel—by pressurizing its two piston sections independently. With an 80 mm bore, each actuated section provides a robust 2513 N of push force at 0.5 MPa, making it suitable for sorting or diverting applications that require a long primary stroke and a short secondary positioning step.
This model is configured with a built-in magnet for direct mounting of CMSG/DMSG sensors and high-temperature Viton seals, shifting the operating range to 0–150 °C. The 25 mm diameter rod and 28 mm adjustable air cushion at each end help manage the inertial loads of the 300 mm stroke section, while the body length A(SCT) of 296 mm provides a compact tandem footprint.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X300X50SH |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 300 / 50 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) | 300 mm |
| P2 (section 2) | 50 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 SCT80X300X50SH Is Used
Two-Stage Part Diverting
Uses the 300 mm stroke to cross a main conveyor and the 50 mm stroke to nudge parts onto a secondary lane, achieving four distinct gate positions with a single actuator.
High-Temperature Gate Control
The Viton seals allow this cylinder to operate a furnace door or hot-material gate at up to 150 °C, using the 50 mm position for a cracked-open venting stage before the full 350 mm opening.
Long-Reach Multi-Depth Pressing
Provides a rapid 300 mm approach stroke and a controlled 50 mm press depth, with the intermediate 50 mm and 300 mm positions used for part loading and ejection clearance.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X300X50SH the Right Cylinder?
Choose the SCT80X300X50SH when your process needs a long 300 mm travel with a precise 50 mm intermediate stop, eliminating the complexity of two separate cylinders and external hard stops. If the 2513 N push force per section is insufficient, stepping up to the 100 mm bore SCT delivers 3927 N at the same pressure. For a drop-in replacement, match an SCT of 80 mm bore, 300 mm and 50 mm strokes, PT ports, and the -S magnet option; this model’s Viton seals also make it the correct choice for high-temperature environments. Because the 300 mm stroke section is extended, ensure the load is guided to prevent side-loading and rod bending during long travels.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 300 + 50 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 SCT80X300X50SH FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 50 mm (section 2 extended), 300 mm (section 1 extended), and 350 mm (both sections extended). The positions are fixed by the two stroke lengths and are selected by pressurizing the appropriate air ports.
It replaces two individual 80 mm bore cylinders and their mounting hardware with a single, compact tandem unit on one piston rod line. This guarantees the relative position between the two strokes is mechanically fixed, eliminating the need to synchronize two separate actuators and simplifying the control system to just two directional valves.
