About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X75
The SCT100X100X75 is a double-acting multi-position cylinder that provides four distinct rod positions: 0 mm (fully retracted), 75 mm, 100 mm, and the total travel of 175 mm. Each 100 mm bore section generates a push force of 3927 N at 0.5 MPa, scaling to 7068 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy-duty sorting or two-depth pressing operations.
This tie-rod cylinder uses a 25 mm diameter rod and PT1/2 port threads, with a body length A(SCT) of 308 mm and a 29 mm adjustable air cushion at each end. The standard TPU seals provide an operating temperature range of -20 to +70 °C, ensuring reliable cycling in general industrial environments.

| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 100 / 75 mm |
| Total travel | 175 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) | 75 mm |
| P3 (both extended) | 175 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 SCT100X100X75 Is Used
4-Position Diverter Gate
Directs heavy packages or pallets to four separate conveyor lanes by actuating the rod to 0, 75, 100, or 175 mm, using simple 5/3-way valve logic.
Two-Depth Heavy Pressing
Performs a primary press at the 100 mm stroke and a secondary, shallower press at 75 mm for forming or assembly operations requiring two distinct force application points.
Multi-Stop Part Feeding
Acts as a heavy-duty stop gate on a roller conveyor, stopping large totes at three different positions (75, 100, 175 mm) for sequential processing stations.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X75 the Right Cylinder?
Select the SCT100X100X75 when a single cylinder must replace a two-cylinder setup for a 4-position sequence, simplifying plumbing and control logic. For applications requiring a higher force per section, this 100 mm bore is the largest in the SCT range; if a lighter, more compact solution is acceptable, consider stepping down to the 80 mm bore (SCT80X100X75), which provides 2513 N of push force per section at 0.5 MPa. To replace this model, match the 100 mm bore, both the 100 mm and 75 mm strokes, PT port thread, and basic mounting style. If the 100 mm stroke section requires guiding against side loads, an external rod guide should be used to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 75 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 SCT100X100X75 FAQ
It provides four distinct mechanical stops: 0 mm (fully retracted), 75 mm (stroke 2 only), 100 mm (stroke 1 only), and 175 mm (both sections extended). The positions are discrete and selected by pressurizing the two cylinder sections individually or together.
Yes, the SCT100X100X75 is designed to replace two independently mounted cylinders with strokes of 100 mm and 75 mm, providing the same four end-of-stroke positions in a single, compact body. Ensure the replacement matches the 100 mm bore, both strokes, PT ports, and basic mounting.
