About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X100
The SCT32X50X100 is a tandem multi-position cylinder that provides four discrete rod positions: 0 mm (fully retracted), 50 mm, 100 mm, and 150 mm total travel. Each 32 mm bore piston section delivers 402 N of push force at 0.5 MPa, making it a compact solution for light-duty sorting and diverting tasks.
This double-acting unit features a 12 mm diameter rod and PT1/8 ports. The tie-rod construction includes a 21 mm adjustable air cushion in each section to manage end-of-stroke impact, with a body length A of 233 mm.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X100 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X100 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 100 mm |
| Total travel | 150 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) | 100 mm |
| P3 (both extended) | 150 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 SCT32X50X100 Is Used
Dual-Stop Part Diverting
Actuates a gate to three positions for routing small components down separate conveyor lanes, using the 50 mm and 100 mm stops.
Multi-Level Dispensing
Positions a dispensing nozzle at two precise heights above a container for layered filling, with the 150 mm stroke as a clear-away position.
Staged Clamping
Applies a light initial clamp at 50 mm extension and a full-pressure clamp at 100 mm, using the per-section force of 724 N at 0.9 MPa.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X100 the Right Cylinder?
Choose the SCT32X50X100 when your sequence requires three distinct extension points plus a home position from a single compact actuator. If you need more push force, step up to the 40 mm bore SCT40, which provides 628 N per section at the same pressure. For replacement, match the 32 mm bore, both 50 mm and 100 mm strokes, PT port thread, and basic mounting configuration.
Since the total travel reaches 150 mm, ensure the load is guided if side forces are present, as the 12 mm rod is designed primarily for axial thrust.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 100 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 SCT32X50X100 FAQ
It provides 4 distinct positions: 0 mm (retracted), 50 mm, 100 mm, and 150 mm (full extension). The positions are achieved by pressurizing the first section, the second section, or both simultaneously.
Yes, it replaces two individual SC32 cylinders with 50 mm and 100 mm strokes in a tandem setup, saving space and simplifying the pneumatic circuit. Ensure the replacement matches the PT port thread and basic mount.
