Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X75
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X75 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 5mm and 75mm give 4 controllable stop positions across a 80mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X75
The SCT32X5X75 tandem cylinder provides four fixed rod positions: fully retracted (0 mm), 5 mm, 75 mm, and the total extended travel of 80 mm. By pressurising either piston section individually or both together, you can index between these stops without external hard stops or multiple actuators. Each 32 mm bore section generates 402 N of push force at 0.5 MPa, rising to 724 N at the maximum operating pressure of 0.9 MPa.
Built on a tie-rod body with a 12 mm diameter piston rod and PT1/8 ports, this model uses a compact 21 mm air cushion at each end for smooth deceleration. The short 5 mm first stroke is ideal for a precise initial positioning or a light clamping action before the main 75 mm working stroke extends. The body length A(SCT) is 233 mm, and the standard TPU seals suit ambient temperatures from -20 to +70 °C.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X75 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X75 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 5 / 75 mm |
| Total travel | 80 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) | 5 mm |
| P2 (section 2) | 75 mm |
| P3 (both extended) | 80 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 SCT32X5X75 Is Used
Two-Stage Clamping
The 5 mm stroke performs a light initial part contact or location clamp, while the 75 mm stroke applies the full holding force, protecting delicate components from impact.
Dual-Position Diverter Gate
Use the 5 mm and 75 mm stops to guide product flow into two separate lanes on a compact conveyor system, eliminating the need for twin actuators.
Multi-Depth Press Insertion
Insert a component to a precise 5 mm pre-set depth, then drive it home with the 75 mm stroke for a two-step assembly process with a single tandem cylinder.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X75 the Right Cylinder?
Choose the SCT when your application needs two or more fixed stopping points along a single linear axis, replacing the complexity of two separate cylinders or an actuator with external mechanical stops. For this 32 mm bore, the per-section push force is 402 N at 0.5 MPa. If you require more thrust, stepping up to the SCT40 series provides 628 N of push per section at the same pressure. A direct replacement must match the 32 mm bore, both the 5 mm and 75 mm strokes, PT port thread, and basic mounting style.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 5 + 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 SCT32-63 Multi-Position Tandem Air Cylinder SCT32X5X75 FAQ
It provides 4 discrete mechanical stops: 0 mm (fully retracted), 5 mm (first section extended), 75 mm (second section extended), and 80 mm (both sections extended, total travel).
Yes, if your sequence requires a 5 mm and a 75 mm stroke from the same rod line. The SCT tandem design integrates both strokes into one tie-rod body, saving space and simplifying your pneumatic circuit and mounting.
