Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X50
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X50 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 50mm and 50mm give 3 controllable stop positions across a 100mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X50
The SCT32X50X50 is a tandem multi-position pneumatic cylinder that provides three fixed stop points along its stroke: fully retracted (0 mm), 50 mm, and the combined 100 mm total travel. Each of the two 32 mm bore sections delivers 402 N of push force at 0.5 MPa, making it a compact solution for light sorting or diverting tasks where two intermediate positions are needed without complex controls.
Built on a durable tie-rod construction with a 12 mm diameter piston rod and M10x1.25 rod thread, this cylinder includes an adjustable air cushion (21 mm length) at each end for smooth deceleration. The body length A is 233 mm, and the standard PT1/8 ports keep plumbing simple. Operating pressure spans 0.15–1.0 MPa, with a proof pressure of 1.5 MPa for safety margin.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X50 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 50 mm |
| Total travel | 100 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) | 50 mm |
| P2 (both extended) | 100 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 SCT32X50X50 Is Used
3-Way Part Sorting
Divert small components to three distinct conveyor lanes by pressurizing section one, section two, or both, achieving precise 0, 50, and 100 mm rod extensions for gate actuation.
Multi-Stop Feeding
Advance material strips or trays in two controlled increments (50 mm and 100 mm) using a single tandem cylinder, ideal for packaging or assembly indexing stations.
Two-Depth Light Pressing
Perform a two-stage insertion or pressing operation where a 50 mm partial advance is followed by a full 100 mm stroke, all managed by simple pneumatic valving on the two cylinder sections.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X50 the Right Cylinder?
Choose the SCT32X50X50 when your application needs three repeatable mechanical stops from a single compact actuator, eliminating the cost and complexity of two separate cylinders with external hard stops. If you require higher force, consider stepping up to the 40 mm bore SCT40X50X50, which provides 628 N of push per section at 0.5 MPa.
For a direct replacement, match the 32 mm bore, both 50 mm strokes, PT port thread, and basic mounting configuration. The SCT series uses a tie-rod body design, so mounting accessories like FA/FB flanges or LB feet must be ordered separately if needed for your setup.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 50 + 50 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 SCT32X50X50 FAQ
This model provides three distinct rod positions because both strokes are equal at 50 mm. The reachable positions are 0 mm (fully retracted), 50 mm (first section extended), and 100 mm (both sections extended, total travel).
Yes, in applications requiring two fixed extension points from a single mounting footprint. It replaces the need for two individual cylinders and external stops, but ensure the per-section force (402 N push at 0.5 MPa) meets your load requirements, as the force does not double when both sections are actuated.
