About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X50S
The SCT32X160X50S is a tandem multi-position cylinder that delivers four fixed rod positions—0 mm, 50 mm, 160 mm, and the full 210 mm extension—by pressurising its two piston sections independently or together. Each section generates 402 N of push force at 0.5 MPa, driven through a 12 mm diameter rod, making it a compact solution for light-duty sorting or diverting tasks.
This model includes a built-in magnet (-S suffix), allowing standard CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke or mid-position sensing. The 32 mm bore body has a length A of 233 mm and uses PT1/8 ports with an M10x1.25 rod thread, with an adjustable air cushion of 21 mm at each end to manage deceleration.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X50S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 160 / 50 mm |
| Total travel | 210 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) | 160 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 210 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 SCT32X160X50S Is Used
Two-Stage Part Diverting
Uses the 50 mm and 160 mm stops to route small components to three different conveyor lanes from a single feed point.
Multi-Depth Light Pressing
Provides two controlled pressing depths (50 mm and 210 mm) for inserting pins or bushings at different heights in an assembly fixture.
Sequential Gate Actuation
Operates a sliding gate with a closed, partially open (50 mm), and fully open (210 mm) position for metering granular materials.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X50S the Right Cylinder?
Choose the SCT32X160X50S when your application needs four distinct mechanical stops without the complexity of servo control or multiple individual cylinders. The unequal strokes create a versatile pattern ideal for two-stage feeding or a diverting gate with an intermediate position. If higher force is required, stepping up to the 40 mm bore provides 628 N of push per section at the same 0.5 MPa pressure.
For a direct replacement, match the 32 mm bore, the exact 160 mm and 50 mm strokes, the PT port thread, and the built-in magnet (-S). This is a basic mounting configuration; if panel mounting is needed, consider an FA or FB flange kit. With a 160 mm section stroke, ensure the external load is guided to prevent excessive side-loading and rod bending during extension.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 160 + 50 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 SCT32X160X50S FAQ
This tandem cylinder provides four discrete rod positions: fully retracted (0 mm), first section extended (50 mm), second section extended (160 mm), and both sections extended for the total travel of 210 mm.
The SCT integrates two piston sections on a single common rod, guaranteeing coaxial alignment and reducing overall footprint. It provides fixed intermediate stops without needing external brackets or couplers, simplifying the mechanical design for multi-position tasks.
