About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X110
The SCT32X50X110 is a tandem multi-position cylinder that delivers four fixed rod positions from two independent piston sections on a common rod line. By pressurising section one, section two, or both, the rod extends to 50 mm, 110 mm, or the total travel of 160 mm, giving you simple, repeatable multi-stop sequencing without complex controls.
Each 32 mm bore section generates 402 N of push force at 0.5 MPa, rising to 724 N at the maximum operating pressure of 0.9 MPa. The cylinder uses a 12 mm diameter rod, M10x1.25 rod thread, and PT1/8 ports, with a 21 mm air cushion at each end for smooth deceleration. The tie-rod body length A(SCT) is 233 mm.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X110 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X110 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 110 mm |
| Total travel | 160 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) | 50 mm |
| P2 (section 2) | 110 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 (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 SCT32X50X110 Is Used
Two-Stage Part Diverting
Operates a diverter gate with three extended positions: a partial open at 50 mm for small parts, a full open at 110 mm for large items, and a combined 160 mm stroke for clearing jams.
Multi-Depth Pressing
Provides two distinct pressing depths in a small assembly fixture. The 50 mm stroke sets an initial insertion, and the 110 mm stroke completes a secondary seating operation, all from one compact actuator.
Selective Pallet Stopping
Acts as a three-position pallet stop on a conveyor. Retracted allows free passage, 50 mm stops a standard pallet, and 160 mm total travel engages a taller stop for heavy or oversized pallets.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X110 the Right Cylinder?
Choose the SCT when a single stroke cylinder with external hard stops is impractical or lacks the required repeatability. This four-position unit replaces two separate actuators and their mounting hardware, saving space and simplifying the pneumatic circuit. If you need more force, stepping up to the 40 mm bore provides 628 N of push per section at 0.5 MPa.
For a direct replacement, match the 32 mm bore, both strokes of 50 mm and 110 mm, PT port thread, and basic mounting style. If your application requires position sensing, order the model with the -S suffix for a built-in magnet compatible with CMSG/DMSG sensors.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 110 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 SCT32X50X110 FAQ
It provides four distinct mechanical stop positions: fully retracted (0 mm), first section extended (50 mm), second section extended (110 mm), and both sections extended for the total travel (160 mm).
No, an SCT cylinder does not lock or hold its position without live air pressure. If the load must be mechanically secured at the 50 mm stop, you will need an external rod brake or a pilot-operated check valve in the circuit.
