About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X75X95
The SCT32X75X95 is a double-acting tandem cylinder that delivers four fixed rod positions from two independent piston sections on a common 12 mm rod. By pressurising the first section, the second, or both simultaneously, the rod extends to 0 mm (retracted), 75 mm, 95 mm, or the full combined travel of 170 mm. Each section generates 402 N of push force at 0.5 MPa, rising to 724 N at the maximum operating pressure of 0.9 MPa.
This 32 mm bore model uses PT1/8 ports and an M10x1.25 rod thread, with a 21 mm adjustable air cushion at each end for smooth deceleration. The body length A(SCT) is 233 mm, making it a compact choice for light-duty multi-stop tasks. It operates on standard filtered air from -20 to +70 °C with its default TPU seals, suiting general industrial environments.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X75X95 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 75 / 95 mm |
| Total travel | 170 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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) | 75 mm |
| P2 (section 2) | 95 mm |
| P3 (both extended) | 170 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCT32X75X95 Is Used
Two-Way Diverter Gate
The four discrete stops (0, 75, 95, 170 mm) allow a single chute gate to direct parts to two separate lanes or a bypass, eliminating a second actuator and simplifying control logic.
Multi-Depth Insertion
Ideal for pressing a component to two distinct depths in sequence. The 75 mm stroke sets the first depth, and the 95 mm stroke completes the second, deeper insertion, all with one compact cylinder.
Staged Part Stops
Use the rod positions to create a three-stage part stop on a conveyor. The 0 mm position allows passage, while the 75 mm and 170 mm extensions stop different pallet sizes without manual adjustment.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X75X95 the Right Cylinder?
Choose the SCT32X75X95 when a single actuator must index between four positions without the complexity of two separate cylinders and external hard stops. The 75 mm and 95 mm strokes create an asymmetric position set ideal for two-step feeding or sorting. If higher force is needed, stepping up to the SCT40 bore provides 628 N of push per section at 0.5 MPa. For replacement, match the 32 mm bore, both the 75 mm and 95 mm strokes, PT port thread, and basic mounting configuration. A direct AirTAC SCT32X75X95 is the only guaranteed drop-in fit.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 75 + 95 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 SCT32X75X95 FAQ
It provides four distinct mechanical stop positions: 0 mm (fully retracted), 75 mm (first section extended), 95 mm (second section extended), and 170 mm (both sections extended for total travel).
While possible, it adds complexity and reduces repeatability. The SCT's internal tandem pistons provide precise, fixed stops. For a direct replacement, you must use an AirTAC SCT32X75X95 with matching PT ports and basic mount to ensure identical form, fit, and function.
