Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X150S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X150S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 150mm and 150mm give 3 controllable stop positions across a 300mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X150S
The SCT32X150X150S is a tandem multi-position cylinder that delivers three defined rod stops: fully retracted, 150 mm, and 300 mm total travel. Each piston section generates 402 N of push force at 0.5 MPa, making it a compact alternative to two separate actuators for three-position sorting tasks.
This model includes a built-in magnet, allowing CMSG or DMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The 12 mm diameter rod and 21 mm air cushion at each end provide smooth deceleration, while the 233 mm body length keeps the footprint tight for space-constrained machines.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X150S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X150S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 150 / 150 mm |
| Total travel | 300 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 150 mm |
| P2 (both extended) | 300 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 SCT32X150X150S Is Used
Three-Position Diverter
Routes packages or small parts to three separate conveyor lanes using the fully retracted, mid-stroke, and fully extended stops.
Two-Depth Pressing
Provides two distinct pressing depths in light assembly fixtures, with the retracted position used for part loading and unloading.
Sensor-Gated Staging
Uses the built-in magnet and external sensors to confirm arrival at each of the three positions before signaling the next machine cycle.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X150S the Right Cylinder?
Choose this SCT when a process needs three fixed mechanical stops without the complexity of two independent cylinders and external hard stops. The 32 mm bore suits light pushing and diverting; if higher force is required, step up to the 40 mm bore which provides 628 N of push per section at the same pressure.
For drop-in replacement, match the 32 mm bore, both 150 mm strokes, PT ports, and the -S magnet option. The basic mount configuration accepts standard foot or flange accessories if mounting needs change later.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 150 + 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 SCT32X150X150S FAQ
It provides three discrete mechanical stop positions because both stroke sections are equal at 150 mm. The rod stops at 0 mm (fully retracted), 150 mm, and 300 mm total extension.
Yes, if your application only needs the three fixed stops at 0, 150, and 300 mm. The SCT uses two pistons on a common rod, eliminating the need to synchronize two separate cylinders and their mountings.
