About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X50
The SCT100X100X50 is a double-acting multi-position pneumatic cylinder that provides four distinct rod positions: fully retracted (0 mm), 50 mm, 100 mm, and the total travel of 150 mm. Each piston section delivers a robust 3927 N of push force at 0.5 MPa, making it suitable for heavy-duty material handling tasks where intermediate stops are essential.
Built on a durable tie-rod body with a length A of 308 mm, this 100 mm bore cylinder uses a 25 mm diameter rod and PT1/2 ports. The integrated air cushion (29 mm length) enables smooth deceleration at each end of the 150 mm total stroke, protecting the end caps during high-cycle operation.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X50 Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X50 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 100 / 50 mm |
| Total travel | 150 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/2 |
| 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, 29 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) | 100 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 150 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SCT100X100X50 Is Used
Two-Stage Sorting Gate
Uses the four positions (0, 50, 100, 150 mm) to direct packages onto three separate conveyor lanes in a logistics hub, with the 150 mm stroke providing a full bypass.
Multi-Depth Clamping
Provides two distinct clamping depths (50 mm and 100 mm) for a woodworking fixture, allowing a single station to process workpieces of two different thicknesses without manual adjustment.
Sequential Part Feeding
Advances components in a 50 mm step, then a 100 mm step, for a total of 150 mm, precisely indexing parts into a stamping press at two different rates from a single magazine.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X50 the Right Cylinder?
Select the SCT100X100X50 when your application requires a compact, single-axis solution to achieve four fixed positions without the complexity of two separate cylinders and external hard stops. This tandem unit simplifies plumbing and mounting compared to a dual-cylinder setup. If your force requirements are lower, stepping down to an 80 mm bore reduces the per-section push force to 2513 N at 0.5 MPa.
To replace an existing unit, match the 100 mm bore, both strokes (100 mm and 50 mm), and PT port thread. This basic configuration has no magnet or mounting brackets, so ensure your mounting method aligns with the cylinder's tie-rod end caps. For strokes of this length, verify the rod is adequately guided if significant side loads are present.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 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 SCT100X100X50 FAQ
This model provides four discrete stop positions: 0 mm (fully retracted), 50 mm (stroke 2 extended alone), 100 mm (stroke 1 extended alone), and 150 mm (both strokes extended for total travel).
Each of the two piston sections independently generates 3927 N of push force and 3681 N of pull force when operated at 0.5 MPa. The multi-position function does not combine the force of the two sections.
