About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X165X150S
The SCT32X165X150S creates four fixed rod positions—0, 150, 165, and 315 mm—by sequencing air to its two tandem piston sections. Each 32 mm bore section delivers 402 N of push force at 0.5 MPa, making it suitable for compact sorting gates or diverters where a 12 mm rod and M10x1.25 thread are adequate.
A built-in magnet lets you clamp CMSG or DMSG sensors directly onto the tie-rod barrel for end-of-stroke or mid-position confirmation. With a 21 mm air cushion at each section and a body length of 233 mm plus strokes, this genuine AirTAC actuator provides repeatable multi-stop indexing without the complexity of servo controls.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X165X150S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X165X150S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 165 / 150 mm |
| Total travel | 315 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) | 165 mm |
| P2 (section 2) | 150 mm |
| P3 (both extended) | 315 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 SCT32X165X150S Is Used
3-Way Diverter Gate
Use the four discrete stops to route packages to three separate conveyor lanes from a single infeed, with the retracted position serving as a home or fourth lane option.
Multi-Depth Label Applicator
Position a tamp pad at 150 mm, 165 mm, or the full 315 mm extension to apply labels to products of varying heights on a mixed-production line.
Staged Part Ejection
Eject good parts to one chute at 150 mm stroke, rework parts to another at 165 mm, and scrap to a third at 315 mm, all from a single pneumatic circuit.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X165X150S the Right Cylinder?
Choose this four-position SCT when your process needs three distinct extended stops plus retracted, avoiding the cost and plumbing of two separate cylinders with external hard stops. If 402 N push per section is marginal, stepping up to the 40 mm bore (SCT40) raises per-section push to 628 N at the same pressure. For direct replacement, match the 32 mm bore, both strokes (165 and 150 mm), the PT port thread, and the integrated magnet (-S suffix); basic mounting means no additional brackets are included. Because the 165 mm section stroke is moderate, standard rod guiding is usually sufficient, but check for side loads if the tooling is offset.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 165 + 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 SCT32X165X150S FAQ
It provides four discrete mechanical stops: 0 mm (fully retracted), 150 mm (section two extended), 165 mm (section one extended), and 315 mm (both sections extended, total travel). The positions are fixed by the two stroke lengths and are not infinitely adjustable.
No. Like all standard pneumatic cylinders, the SCT32X165X150S will drift or drop if pressure is exhausted or a directional valve is centered. If you need to hold a load at one of the four stops without live pressure, you must add an external rod lock or a pilot-operated check valve.
