Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X150
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X150 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 100mm and 150mm give 4 controllable stop positions across a 250mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X150
The SCT32X100X150 is a tandem multi-position cylinder that provides four fixed rod positions without external stops: 0 mm (fully retracted), 100 mm, 150 mm, and 250 mm (total travel). Each 32 mm bore piston section generates 402 N of push force at 0.5 MPa, making it suitable for light sorting or diverting tasks where two distinct extended positions are required from a single actuator.
Built on a tie-rod platform with a 12 mm diameter rod and M10x1.25 rod thread, this model includes a 21 mm adjustable air cushion in each section to manage end-of-stroke deceleration. The PT1/8 ports and standard TPU seals cover a -20 to +70 °C operating range, while the 233 mm body length A(SCT) keeps the assembly compact for space-constrained multi-stop stations.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X150 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 100 / 150 mm |
| Total travel | 250 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) | 100 mm |
| P2 (section 2) | 150 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 (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 SCT32X100X150 Is Used
Two-Way Part Sorting
Use the 100 mm and 250 mm positions to divert parts onto two separate conveyor lanes from a single feed point, simplifying pneumatic control.
Multi-Depth Label Application
Apply labels at two different heights (100 mm and 150 mm extensions) on stepped product surfaces without changing tooling or adding a second cylinder.
Staged Clamping
Execute a two-stage clamping sequence: first contact at 100 mm with lower force, then full clamp travel at 250 mm, all from one compact tandem unit.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X150 the Right Cylinder?
Choose the SCT32X100X150 when your process needs two different extended positions from one actuator, eliminating the cost and complexity of mounting two separate cylinders with hard stops. If you require higher force at each stop, step up to the 40 mm bore SCT40X100X150, which provides 628 N of push per section at the same 0.5 MPa pressure. For a direct replacement, match the 32 mm bore, both the 100 mm and 150 mm section strokes, PT port thread, and basic mounting configuration. Since the total travel reaches 250 mm, ensure the rod is guided if the load applies significant side force or the stroke is fully extended under offset weight.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 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 SCT32X100X150 FAQ
It provides four discrete mechanical stops: 0 mm (fully retracted), 100 mm (first section extended), 150 mm (second section extended), and 250 mm (both sections extended for full travel).
Yes, if your application requires two fixed extended positions at 100 mm and 150 mm (or 250 mm total). The SCT tandem body replaces two individual cylinders and their mounting brackets, but you must match the port thread (PT) and verify that 402 N of push force per section meets your load requirements at each stop.
