Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X270
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X270 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 80mm and 270mm give 4 controllable stop positions across a 350mm total travel, with a Ø50mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X270
The SCT50X80X270 is a 50 mm bore tandem cylinder that provides four distinct, repeatable rod positions without external hard stops. By pressurising either or both piston sections, the rod extends to exactly 0 mm (retracted), 80 mm, 270 mm, or the full combined travel of 350 mm.
Each section generates 982 N of push force at 0.5 MPa, rising to 1767 N at the 0.9 MPa maximum operating pressure. The cylinder uses a 20 mm diameter rod, PT1/4 ports, and an adjustable air cushion with a 21 mm cushion length to manage end-of-stroke deceleration. The tie-rod body has an A(SCT) dimension of 243 mm.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X270 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 80 / 270 mm |
| Total travel | 350 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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, 21 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) | 80 mm |
| P2 (section 2) | 270 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X270 Is Used
Two-Stage Part Diverting
Operates a diverter gate with three positions: a neutral home position, a first divert path at 80 mm, and a second divert path at 270 mm, sorting parts to three different conveyor lanes.
Sequential Clamping
Applies a light clamp force at the 80 mm stop for part location, then drives to the 270 mm position for a secondary, deeper clamping operation, all from one compact actuator.
Multi-Depth Stop Gate
Controls a product stop on a packaging line, raising to a low-profile stop at 80 mm for small boxes and a taller stop at 270 mm for large cases, improving line flexibility.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X270 the Right Cylinder?
Choose the SCT50X80X270 when your process needs a single actuator to stop reliably at two intermediate points plus the fully retracted and fully extended positions. This tandem unit is more compact and cost-effective than linking two separate 50 mm bore cylinders with external bracketry and stop valves. If higher force is needed, stepping up to a 63 mm bore SCT63X80X270 provides 1559 N of push per section at 0.5 MPa. A direct replacement must match the 50 mm bore, both the 80 mm and 270 mm strokes, PT port thread, and basic mounting configuration.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 80 + 270 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 SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X270 FAQ
This 4-position cylinder provides discrete stops at 0 mm (fully retracted), 80 mm (section 1 extended), 270 mm (section 2 extended), and 350 mm (both sections extended, total travel).
The force output is per actuated piston section. Each section provides 982 N of push force and 825 N of pull force when operated at 0.5 MPa air pressure. The force does not double when both sections are pressurised for a multi-position move.
