About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X150S
The SCT63X10X150S is a double-acting multi-position tandem cylinder that delivers four fixed rod positions: fully retracted (0 mm), 10 mm, 150 mm, and the total travel of 160 mm. Each piston section provides a push force of 1559 N at 0.5 MPa, making it suitable for applications requiring two distinct short extension depths from a single compact actuator.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position feedback. The 63 mm bore features a 20 mm diameter rod with an M16x1.5 thread and PT1/4 ports, and the body has a 28 mm adjustable air cushion to manage end-of-stroke deceleration.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X150S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 10 / 150 mm |
| Total travel | 160 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) | 10 mm |
| P2 (section 2) | 150 mm |
| P3 (both extended) | 160 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 SCT63X10X150S Is Used
Two-Stage Clamping
A rapid 10 mm advance positions a clamp near the workpiece, followed by a controlled 150 mm high-force stroke to secure it, preventing collision at full speed.
Part Orientation
Uses the 10 mm and 150 mm stops to tilt or rotate a chute, directing parts to different conveyor lanes based on a signal from the magnetic sensors.
Dual-Depth Pressing
Executes a light 10 mm pre-press for alignment, then a full 150 mm insertion stroke, with the magnet confirming each position before the next cycle starts.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X150S the Right Cylinder?
Select the SCT63X10X150S when your process needs two different preset stop positions without the complexity of two separate cylinders and valves. The 10 mm stroke provides a precise short advance, while the 150 mm stroke handles the main working travel. If higher force is required, consider stepping up to the 80 mm bore, which delivers 2513 N of push per section at 0.5 MPa. For a direct replacement, match the 63 mm bore, both strokes (10 mm and 150 mm), PT port thread, and the integrated magnet.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 10 + 150 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 SCT63X10X150S FAQ
This tandem cylinder provides four discrete rod positions: 0 mm (fully retracted), 10 mm, 150 mm, and 160 mm (10+150). The positions are achieved by pressurizing the front section, rear section, or both simultaneously.
An SCT tandem cylinder uses a common rod and piston line, guaranteeing a fixed spatial relationship between the two strokes in a single, compact body. This eliminates the need to synchronize two separate actuators and reduces the overall footprint and plumbing complexity.
