About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X75S
The AirTAC SCT32X50X75S is a tie-rod multi-position cylinder that delivers four fixed rod positions—0 mm, 50 mm, 75 mm, and the combined 125 mm—by independently pressurising its two piston sections. Each section generates 402 N of push force at 0.5 MPa, with a 12 mm diameter rod and PT1/8 ports. The built-in magnet allows direct mounting of CMSG/DMSG sensors for position feedback.
With a body length A of 233 mm and 21 mm of adjustable air cushion at each end, this 32 mm bore tandem unit is ideal for compact sorting or diverting stations where multiple mechanical stops are needed without complex controls. The discrete stop positions are fixed by the stroke lengths, providing repeatable, reliable positioning in a single actuator package.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X75S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X75S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 75 mm |
| Total travel | 125 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) | 50 mm |
| P2 (section 2) | 75 mm |
| P3 (both extended) | 125 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 SCT32X50X75S Is Used
Multi-Stop Diverter Gate
Positions a diverter gate at four distinct angles (0, 50, 75, 125 mm) to route packages down different conveyor lanes, using the built-in magnet for gate position confirmation.
Two-Depth Pressing Station
Provides two controlled pressing depths (50 mm and 75 mm) plus full retraction and full extension (125 mm) for a two-step assembly or staking operation.
Sequential Part Feeding
Advances parts in a magazine with a three-step push sequence: a 50 mm pre-feed, a 75 mm main feed, and a combined 125 mm final ejection stroke, all from one compact cylinder.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X75S the Right Cylinder?
Choose the SCT32 tandem when your application requires up to four distinct end-of-stroke positions from a single pneumatic circuit, eliminating the cost and complexity of two separate cylinders with external stops. If higher force is needed, stepping up to the 40 mm bore SCT40 provides 628 N of push per section at the same 0.5 MPa pressure. For replacement, match the 32 mm bore, both strokes (50 mm and 75 mm), PT port thread, and the -S magnet option; basic mounting is standard. Note that for combined strokes exceeding 300 mm, consider external guides to protect the 12 mm rod from side loads.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 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 SCT32X50X75S FAQ
This model provides 4 discrete stop positions: 0 mm (fully retracted), 50 mm (section 1 extended), 75 mm (section 2 extended), and 125 mm (both sections extended, which is the sum of the two strokes).
Yes, if your sequence requires fixed 50 mm and 75 mm strokes. The SCT32X50X75S combines both into one tie-rod body, reducing mounting hardware and eliminating the need to synchronize two separate actuators. Ensure your mounting interface and porting (PT1/8) match.
