About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X30
The SCT32X50X30 is a double-acting tandem cylinder that provides four fixed rod positions: fully retracted (0 mm), 30 mm, 50 mm, and the combined total travel of 80 mm. Each 32 mm bore section delivers 402 N of push force and 345 N of pull force at a standard 0.5 MPa operating pressure, making it suitable for light-duty sorting and diverting tasks.
Built on a tie-rod platform with a 12 mm diameter piston rod and M10x1.25 rod-end threads, this cylinder uses PT1/8 ports and features a 21 mm adjustable air cushion at each end. The body length A(SCT) is 233 mm, providing a compact footprint for multi-stop linear motion where space is limited.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X30 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X30 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 30 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) | 50 mm |
| P2 (section 2) | 30 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 SCT32X50X30 Is Used
Two-Way Part Diverting
Uses the 30 mm and 80 mm positions to guide small components down two different conveyor lanes from a single feed point, simplifying the actuator layout.
Multi-Depth Stop Gate
The 50 mm and 80 mm extensions act as a two-stage gate, stopping pallets at different positions on a gravity roller track for accumulation or release.
Selective Depth Pressing
Provides two controlled pressing depths (30 mm and 50 mm) in a light assembly fixture, ensuring consistent insertion force for different component heights.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X30 the Right Cylinder?
Choose the SCT32X50X30 when your application requires two distinct extension stops without the complexity of two separate cylinders and external hard stops. The four-position capability (0, 30, 50, 80 mm) is ideal for sequencing parts to different depths. If you need more thrust, consider stepping up to the SCT40 bore, which provides 628 N of push force per section at 0.5 MPa.
For a direct replacement, match the 32 mm bore, the exact strokes of 50 mm and 30 mm, PT port threads, and the basic mounting configuration. If your process requires magnetic piston sensing, specify the -S suffix to enable CMSG or DMSG sensor mounting directly on the tie-rod barrel.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 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 SCT32X50X30 FAQ
This model provides four distinct mechanical stop positions. The rod can be positioned at 0 mm (fully retracted), 30 mm (stroke 2 only), 50 mm (stroke 1 only), and 80 mm (both strokes combined, full extension).
Each of the two 32 mm bore sections independently produces 402 N of push force and 345 N of pull force at 0.5 MPa. At the maximum operating pressure of 1.0 MPa, the theoretical push force per section is 804 N.
