About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X50S
The AirTAC SCT63X150X50S tandem cylinder delivers four fixed rod positions—0 mm, 50 mm, 150 mm, and 200 mm—by pressurising one or both piston sections. This discrete multi-stop capability eliminates the complexity of two separate cylinders and external stops for sequenced linear moves. Each section generates 1559 N of push force at 0.5 MPa, rising to 2805 N at 0.9 MPa, driven through a 20 mm diameter chrome-plated rod.
A built-in magnet is integrated into the piston, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The body length A is 249 mm, and the adjustable air cushion at each end (28 mm long) decelerates the load smoothly. This genuine AirTAC unit uses PT ports and operates on standard filtered air from 0.15 to 1.0 MPa.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X50S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 150 / 50 mm |
| Total travel | 200 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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, 28 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) | 150 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 200 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 SCT63X150X50S Is Used
Two-Stage Part Feeding
Advances a workpiece 150 mm to a staging area, then uses the 50 mm stroke for a final precise placement into a nest or fixture, all from one compact cylinder.
Diverting Gate Actuation
Positions a gate at 0 mm (closed), 50 mm (partial divert), 150 mm (full divert), or 200 mm (bypass), directing product flow on a conveyor line.
Two-Depth Pressing
Provides a 150 mm rapid approach stroke followed by a controlled 50 mm pressing stroke, achieving two distinct forming depths without tooling changes.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X50S the Right Cylinder?
Select the SCT63X150X50S when your application requires four distinct mechanical stops without the cost and alignment hassle of multiple actuators. The 150 mm and 50 mm strokes create an asymmetric position set ideal for a long advance followed by a short secondary feed. If the 1559 N push force per section is insufficient, stepping up to the SCT80 bore provides 2513 N per section at the same 0.5 MPa pressure. For replacement, match the 63 mm bore, both the 150 mm and 50 mm strokes, PT thread, and the -S magnet option exactly.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 150 + 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 SCT63X150X50S FAQ
The rod stops at four discrete positions: 0 mm (fully retracted), 50 mm (section 2 extended), 150 mm (section 1 extended), and 200 mm (both sections extended).
No, it is a standard double-acting cylinder. If pressure is lost or the valve centers, the piston can drift. To hold a load at an intermediate stop without live pressure, you must add an external rod lock or a pilot-operated check valve.
