About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X175X95
The AirTAC SCT32X175X95 is a double-acting tandem cylinder that delivers four distinct rod positions by pressurising its two piston sections independently or together. The reachable stops are 0 mm (fully retracted), 95 mm, 175 mm, and the combined total travel of 270 mm. Each section uses a 12 mm diameter rod and provides a push force of 402 N at 0.5 MPa.
This tie-rod cylinder features an adjustable pneumatic cushion at both ends with a cushion length of 21 mm to decelerate the load. The body length A(SCT) is 233 mm, and the port size is PT1/8. It is ideal for sorting or diverting tasks where a single actuator must index to multiple fixed locations without needing complex electronic controls.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X175X95 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 175 / 95 mm |
| Total travel | 270 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) | 175 mm |
| P2 (section 2) | 95 mm |
| P3 (both extended) | 270 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 SCT32X175X95 Is Used
Two-Stage Sorting Gate
Uses the four positions to divert packages to four separate conveyor lanes. The first stroke moves to an intermediate height, and the second completes the full divert.
Multi-Depth Clamping
Applies two distinct clamping pressures or depths on a workpiece. The 95 mm stroke provides a light hold, while the 175 mm stroke applies full clamping force.
Indexing Stopper
Acts as a programmable hard stop in a linear transfer line, stopping pallets at 95 mm, 175 mm, or the full 270 mm position for different process steps.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X175X95 the Right Cylinder?
Select the SCT32X175X95 when your application needs four fixed mechanical stops from one compact actuator, eliminating the cost and complexity of two separate cylinders and their mounting hardware. If your load requires more force, consider stepping up to the 40 mm bore SCT, which provides 628 N of push per section at the same 0.5 MPa pressure. For a direct replacement, match the 32 mm bore, both the 175 mm and 95 mm strokes, the PT1/8 port thread, and the basic mounting style. Since the longer 175 mm stroke section is present, ensure the rod is adequately guided if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 175 + 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 SCT32X175X95 FAQ
This tandem cylinder provides four discrete stop positions. The rod can be positioned at 0 mm, 95 mm, 175 mm, and the full combined stroke of 270 mm by pressurising the sections individually or together.
The force is generated per actuated piston section. At 0.5 MPa, a single section provides 402 N of push force and 345 N of pull force. The two sections do not add their force together for a combined push.
