About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X50X10S
The AirTAC SCT80X50X10S is a tandem multi-position pneumatic cylinder that delivers four distinct, repeatable stop positions along its stroke: 0 mm (fully retracted), 10 mm, 50 mm, and the combined total travel of 60 mm. Each actuated piston section provides a robust push force of 2513 N at 0.5 MPa, making it suitable for tasks requiring two different short extension depths from a single compact unit.
This model features an 80 mm bore with a 25 mm diameter piston rod and PT3/8 ports. The built-in magnet (-S suffix) allows for direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for non-contact position sensing. The cylinder body has an A-length of 296 mm and uses an adjustable pneumatic cushion of 28 mm to manage end-of-stroke deceleration.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X50X10S Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X50X10S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 50 / 10 mm |
| Total travel | 60 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) | 50 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 60 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 SCT80X50X10S Is Used
Two-Stage Sorting Gate
Uses the 10 mm stroke for a partial gate opening to divert small items and the 50 mm stroke for a full opening to pass larger packages, all controlled from one cylinder.
Dual-Depth Labeling
Applies a label with a light 10 mm touch-down stroke, then follows with a 50 mm pressure stroke for full adhesion, ensuring precise placement without product damage.
Multi-Stop Clamping Fixture
Provides a 10 mm low-force pre-clamp to align a delicate part, followed by a 50 mm high-force stroke to securely lock it for machining or assembly.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X50X10S the Right Cylinder?
Select the SCT80X50X10S when your application requires two distinct short extension lengths, such as a 10 mm pre-position and a 50 mm working stroke, without the complexity of two separate cylinders and valves. For a higher force per section, step up to the 100 mm bore (3927 N push at 0.5 MPa); for a lighter, more compact solution, the 63 mm bore offers 1559 N push. This unit is a direct replacement for another SCT80 with 50 mm and 10 mm strokes, PT ports, and a built-in magnet.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 10 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 SCT80X50X10S FAQ
This tandem cylinder provides 4 discrete mechanical stops. The rod positions are 0 mm (fully retracted), 10 mm (stroke 2 only), 50 mm (stroke 1 only), and 60 mm (both strokes extended).
Each of the two piston sections generates a push force of 2513 N at 0.5 MPa and a pull force of 2268 N. The force is per section and does not double when both are actuated simultaneously.
