About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X15S
The SCT32X50X15S is a double-acting multi-position tandem cylinder that delivers four fixed rod positions: fully retracted (0 mm), 15 mm, 50 mm, and the combined total travel of 65 mm. Each piston section generates 402 N of push force at 0.5 MPa, driven through a 12 mm diameter rod. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for position feedback.
With a compact body length A of 233 mm and a 21 mm adjustable air cushion, this tie-rod cylinder is suited for light-duty sorting or diverting tasks requiring multiple stop points without complex controls. The PT1/8 ports and standard TPU seals support an operating pressure of 0.15–1.0 MPa across a temperature range of -20 to +70 °C.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X15S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X15S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 15 mm |
| Total travel | 65 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) | 15 mm |
| P3 (both extended) | 65 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 SCT32X50X15S Is Used
Two-Way Diverter Gate
Use the four distinct positions to route packages to two separate conveyor lanes from a single infeed point, with a retracted home position and an extended clearing stop.
Multi-Depth Stamping
Achieve two different pressing depths (15 mm and 50 mm) in a single cycle for parts that require a shallow pre-form before a final deep draw, using the 65 mm total stroke for ejection.
Component Sorting Station
Sort mixed parts by height. The 15 mm stop checks short components, the 50 mm stop checks mid-size ones, and the 65 mm position rejects tall parts, all verified by the cylinder's magnetic sensors.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X15S the Right Cylinder?
Choose the SCT32X50X15S when your application needs four distinct mechanical stops from a single pneumatic unit, eliminating the cost and complexity of two separate cylinders with external hard stops. This model is a direct replacement for another AirTAC SCT32X50X15S with a magnet and PT ports. If higher force is needed, stepping up to the 40 mm bore provides 628 N of push per section at 0.5 MPa. For strokes over 300 mm, evaluate the rod bearing support to prevent side-load deflection.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 15 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 SCT32X50X15S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 15 mm (section 2 extended), 50 mm (section 1 extended), and 65 mm (both sections extended). It does not provide infinitely variable positioning.
Yes, it is designed as a compact alternative to two single-rod cylinders mounted back-to-back. To be a drop-in replacement, the replacement SCT unit must match the 32 mm bore, 50 mm and 15 mm strokes, PT port thread, and the integrated magnet sensor option.
