Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X350X350
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X350X350 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 350mm and 350mm give 3 controllable stop positions across a 700mm total travel, with a Ø63mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X350X350
The SCT63X350X350 is a tandem multi-position cylinder that provides three fixed rod positions: fully retracted (0 mm), mid-stop at 350 mm, and fully extended at 700 mm total travel. Each piston section generates 1559 N of push force at 0.5 MPa, scaling to 2805 N at the maximum operating pressure of 0.9 MPa, making it suitable for sorting or diverting tasks where two distinct extended stops are required.
This 63 mm bore model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The tie-rod construction includes a 28 mm adjustable air cushion in each section to manage end-of-stroke deceleration. The body length A(SCT) is 249 mm, and the cylinder operates on filtered air within a standard temperature range of -20 to +70 °C.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X350X350 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 350 / 350 mm |
| Total travel | 700 mm |
| Stop positions | 3 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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, 28 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) | 350 mm |
| P2 (both extended) | 700 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 SCT63X350X350 Is Used
Two-Way Diverter Gate
Actuate a chute or diverter plate to three positions: closed (0 mm), divert to lane A (350 mm), and divert to lane B (700 mm) for routing packages on a conveyor line.
Multi-Depth Pressing
Control a press platen to two distinct working depths. The 350 mm stop sets a pre-compression height, while the full 700 mm extension applies final forming pressure to the workpiece.
Staged Part Transfer
Move components between three inline stations on an assembly dial. Retract to pick, extend to 350 mm for an inspection camera, and extend fully to 700 mm for the drop-off nest.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X350X350 the Right Cylinder?
Choose the SCT tandem cylinder when your application needs two positive, repeatable stop locations without the complexity of external hard stops or two separate actuators. With equal 350 mm strokes, this model creates a 700 mm total travel with a precise intermediate position, simplifying the pneumatic circuit compared to sequencing two individual cylinders. If your force requirement is lower, stepping down to the 50 mm bore reduces per-section push to 982 N at 0.5 MPa.
For a drop-in replacement, match the 63 mm bore, both 350 mm section strokes, and PT port thread. Note that with a combined stroke of 700 mm, the rod is fully supported only at the front and rear bearings; for applications with significant side loads, external guide rods or a linear slide should be used to prevent rod bending and premature seal wear.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 350 + 350 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 SCT63X350X350 FAQ
It provides 3 discrete mechanical stops because both section strokes are equal at 350 mm. The rod positions are 0 mm (fully retracted), 350 mm (one section extended), and 700 mm (both sections extended for total travel).
Yes, in many cases. A single SCT63X350X350 with a 700 mm total stroke and a mid-stop replaces two SC63X350 cylinders mounted back-to-back, saving space and eliminating the need to synchronize two separate air circuits. Ensure the port size (PT1/4) and mounting style match your machine layout.
