About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X160X90S
The SCT63X160X90S is a double-acting multi-position cylinder that delivers four fixed rod positions from a single compact assembly: fully retracted (0 mm), 90 mm, 160 mm, and the total extended travel of 250 mm. Each piston section generates a push force of 1559 N at 0.5 MPa, scaling up to 2805 N at the maximum operating pressure of 0.9 MPa, making it a robust choice for sequenced material handling tasks.
This model integrates a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors to the tie-rod barrel for non-contact position feedback at each stop. The 63 mm bore cylinder uses a 20 mm diameter piston rod with M16x1.5 threads, PT1/4 ports, and a 28 mm adjustable air cushion at each end to decelerate the load smoothly.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X160X90S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | ร63 mm |
| Stroke 1 / Stroke 2 | 160 / 90 mm |
| Total travel | 250 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16ร1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 โ 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 โ 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 32โ100; 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) | 160 mm |
| P2 (section 2) | 90 mm |
| P3 (both extended) | 250 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 (ร63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | โ |
| 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 SCT63X160X90S Is Used
4-Position Diverter Gate
Actuates a chute or gate to four distinct angles for sorting packages or bulk materials to separate conveyors, using the 0, 90, 160, and 250 mm stops.
Two-Depth Pressing Station
Provides a partial advance at 90 mm for a light forming operation, followed by a full 250 mm stroke for a deep draw, all controlled by pressurizing the two cylinder sections.
Multi-Step Assembly Fixture
Positions a component at three working heights (90, 160, 250 mm) for sequential drilling, tapping, and insertion, with sensor confirmation at each stop via the built-in magnet.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X160X90S the Right Cylinder?
Select this SCT when your process requires four distinct mechanical stop points without the complexity of servo controls or multiple actuators. The 160 mm and 90 mm stroke sections provide asymmetric positioning ideal for two-step pressing or diverting. If your force requirement is lower, consider stepping down to the 50 mm bore SCT, which provides 982 N of push per section at 0.5 MPa. For a direct replacement, match the 63 mm bore, both the 160 mm and 90 mm strokes, the PT port thread, and the integrated magnet (-S suffix).
With a combined stroke of 250 mm, ensure the load is guided if side forces are present, as the tandem rod design is intended for axial thrust. This cylinder is a tie-rod type and is not dimensionally interchangeable with ISO 15552 profiles.
Multi-position checklist
- โ Need 4 repeatable stops?
- โ Section strokes 160 + 90 mm suit your layout?
- โ Required force at your working pressure
- โ Port/thread type (PT/NPT/G)
- โ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 โ 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 SCT63X160X90S FAQ
This tandem cylinder provides four discrete mechanical stops. The rod positions are 0 mm (fully retracted), 90 mm (stroke of section two), 160 mm (stroke of section one), and 250 mm (total travel when both sections are pressurized).
For a drop-in replacement, you must match the 63 mm bore, the specific 160 mm and 90 mm strokes, the PT port thread, and the -S magnet option for sensor compatibility. The mounting style must also match your current setup; this basic model has no attached brackets.
