About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X160S
The SCT32X15X160S tandem cylinder delivers four distinct rod positions—0, 15, 160, and 175 mm—from its two integrated piston sections. Each section generates 402 N of push force at 0.5 MPa, making it a compact alternative to using two separate actuators for a two-stop sequence. The 12 mm diameter rod and PT1/8 ports keep the unit lightweight for its 233 mm body length.
A built-in magnet is included with this -S model, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position feedback at each stop. The adjustable pneumatic cushion at both ends of the 21 mm cushion stroke smooths deceleration, protecting the assembly when shifting between the short 15 mm and longer 160 mm strokes at speeds up to 800 mm/s.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X160S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 15 / 160 mm |
| Total travel | 175 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) | 15 mm |
| P2 (section 2) | 160 mm |
| P3 (both extended) | 175 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 SCT32X15X160S Is Used
Two-Stage Diverter Gate
Uses the 15 mm stroke to clear a gate seal and the 160 mm stroke to fully open the material path, giving a clean two-step actuation from one compact cylinder.
Multi-Depth Assembly Press
Provides a light 15 mm pre-press position followed by a full 175 mm insertion stroke, controlling two distinct force applications in a single automated cycle.
Tandem Part Staging
Stops at 15 mm for part presence verification via the magnetic sensor, then extends to 160 mm to push the verified component onto the next conveyor lane.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X160S the Right Cylinder?
Choose the SCT32X15X160S when a single actuator must provide a precise short extension and a longer secondary position without the complexity of external hard stops. The 15 mm stroke handles a quick pick or gate action, while the 160 mm stroke completes the main transfer. If higher force is needed, stepping up to the 40 mm bore provides 628 N of push per section at the same pressure. For replacement, match the 32 mm bore, both 15 mm and 160 mm strokes, PT port thread, and the -S magnet option. The basic mounting style accepts standard foot or flange accessories if a fixed installation is later required.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 15 + 160 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 SCT32X15X160S FAQ
It provides four distinct mechanical stops: fully retracted (0 mm), the first section extended (15 mm), the second section extended (160 mm), and both sections extended for the total travel of 175 mm. The built-in magnet allows a sensor to confirm arrival at each position.
Yes, in applications requiring two fixed stroke lengths from a single mounting point. It eliminates the need for dual mounting brackets and synchronisation valves. Ensure the per-section force of 402 N push at 0.5 MPa meets your load requirement at each stop.
