About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X110X30
The SCT32X110X30 is a double-acting multi-position pneumatic cylinder that provides four fixed rod positions: 0 mm (fully retracted), 30 mm, 110 mm, and a total extended travel of 140 mm. By pressurizing either of its two piston sections independently or together, this 32 mm bore tandem design delivers a per-section push force of 402 N at 0.5 MPa, scaling up to 724 N at the maximum operating pressure of 0.9 MPa.
Built on a durable tie-rod construction with a 12 mm diameter piston rod and M10x1.25 rod thread, this cylinder includes an adjustable pneumatic cushion (21 mm length) for end-of-stroke deceleration. The PT1/8 port connections and a body length of 233 mm make it a compact solution for space-constrained multi-stop tasks, operating reliably with filtered air between -20 and +70 °C.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X110X30 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 110 / 30 mm |
| Total travel | 140 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) | 110 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 140 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 SCT32X110X30 Is Used
Two-Position Part Diverting
Uses the 30 mm and 110 mm stops to route parts to two separate conveyor lanes from a single pick point, simplifying actuator count on sorting systems.
Sequential Clamping
Applies an initial low-force 30 mm clamp for delicate alignment, followed by a full 140 mm travel for a secondary high-force press, controlled by valving each section.
Staged Dispensing
Positions a dispensing head at two precise heights (30 mm and 110 mm) for applying fluid to components of different sizes on an automated assembly fixture.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X110X30 the Right Cylinder?
Select the SCT32X110X30 when an application requires two distinct extended work positions without the complexity of dual cylinders and external hard stops. This model is ideal where a short 30 mm advance is needed for one operation and a longer 110 mm stroke for another, all from a single actuator body. If higher force is required, consider stepping up to the 40 mm bore SCT series, which offers 628 N of push per section at 0.5 MPa.
For a direct replacement, match the 32 mm bore, both stroke lengths (110 mm and 30 mm), PT port thread, and basic mounting configuration. Since the longer 110 mm section stroke exceeds 100 mm, ensure the external load is guided to prevent side-loading and rod bending, which can accelerate seal wear and reduce cylinder life.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 110 + 30 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 SCT32X110X30 FAQ
This model provides four discrete mechanical stops: 0 mm (fully retracted), 30 mm, 110 mm, and the full combined stroke of 140 mm. The positions are achieved by pressurizing the first section, the second section, or both sections simultaneously.
No. Like all standard pneumatic cylinders, the SCT32X110X30 will not hold its position if air pressure is lost or the directional control valve is centered. The piston can drift or drop under load. To safely hold a load at any of the four stops without live pressure, an external pilot-operated check valve or a mechanical rod locking device must be added to the circuit.
