About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X9
The SCT32X15X9 is a compact tandem cylinder that delivers four fixed rod positions—0 mm, 15 mm, 9 mm, and 24 mm total travel—from two independently controlled piston sections on a single 12 mm rod line. Each section generates 402 N of push force at 0.5 MPa (724 N at 0.9 MPa), making it suitable for light-duty sorting or staging tasks where two short, distinct advances are needed without multiple actuators.
Built on a tie-rod body with a 233 mm base length and 21 mm adjustable air cushion at each end, this 32 mm bore unit uses PT1/8 ports and an M10x1.25 rod thread. The strokes are non-standard lengths, configured to order for applications requiring a precise 15 mm primary move and a 9 mm secondary step.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X9 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X9 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 15 / 9 mm |
| Total travel | 24 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) | 9 mm |
| P3 (both extended) | 24 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 SCT32X15X9 Is Used
Two-Step Part Staging
Advances a stop pin to a 15 mm pre-stage position, then a final 9 mm locate position, giving a clean two-step sequence for small part fixtures.
Compact Diverter Gate
Uses the 15 mm and 24 mm positions to open a small gate to two different flow paths in a chute or conveyor junction.
Dual-Depth Label Press
Applies light pressure at a 9 mm kiss-contact depth and full pressure at the 24 mm extended position for two-stage label application.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X9 the Right Cylinder?
Choose this four-position tandem when your sequence needs a short primary advance and a finer secondary step from one compact assembly, eliminating the need for two separate 32 mm bore cylinders and their mounting hardware. If your force requirement is higher, the 40 mm bore SCT offers 628 N push per section at 0.5 MPa. For direct replacement, match the 32 mm bore, both 15 mm and 9 mm strokes, PT port thread, and basic mounting. Since the combined stroke is under 300 mm, rod buckling is typically not a concern in axial-load applications.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 15 + 9 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 SCT32X15X9 FAQ
It provides four discrete mechanical stops: fully retracted (0 mm), first section extended (15 mm), second section extended (9 mm), and both sections extended (24 mm total travel). The positions are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, it combines two short-stroke piston sections on one common rod line, giving you two independent advances from a single body. Ensure the replacement matches the 32 mm bore, 15 mm and 9 mm strokes, PT1/8 ports, and basic mounting configuration.
