About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X100X40S
The SCT50X100X40S is a double-acting tandem cylinder that delivers four fixed rod positions—0 mm, 40 mm, 100 mm, and the full 140 mm combined travel—by independently pressurising its two piston sections. Each section generates a push force of 982 N at 0.5 MPa (up to 1767 N at 0.9 MPa), driven by a 20 mm diameter rod. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for position feedback.
This model uses a 50 mm bore with PT1/4 ports and an M16x1.5 rod thread, featuring a 21 mm adjustable air cushion in each section for smooth deceleration. The tie-rod construction provides a robust body with an A-length of 243 mm, suited for multi-stop sorting or diverting tasks where sensor confirmation of each position is required.

| 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, 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) | 40 mm |
| P3 (both extended) | 140 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 SCT50X100X40S Is Used
Two-Stage Part Diverting
Use the four positions (0, 40, 100, 140 mm) to route parts to three different conveyor lanes. The magnet sensors confirm arrival at each stop, ensuring reliable sorting without needing multiple actuators.
Multi-Depth Pressing
Achieve two distinct pressing depths in one cycle. The 40 mm stroke handles a shallow pre-form operation, while the 100 mm stroke completes the full-depth insertion, with the 140 mm position available for part ejection.
Sequential Gate Control
Operate a three-position gate or shutter. The rod extends to 40 mm for a partial open, 100 mm for a material feed position, and the full 140 mm for a clear-pass or cleaning access point, all verified by onboard sensors.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X100X40S the Right Cylinder?
Choose the SCT when a single cylinder must provide multiple defined stop points, eliminating the complexity of two separate cylinders and external hard stops. The SCT50X100X40S gives you four discrete positions from two strokes, simplifying pneumatic circuits for sequencing tasks. If a higher force per section is needed, consider stepping up to the 63 mm bore SCT, which provides 1559 N of push at 0.5 MPa. For a direct replacement, match the 50 mm bore, both strokes (100 mm and 40 mm), PT port thread, basic mounting, and the -S magnet option; this sensor-ready configuration is specific to the AirTAC SCT series.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 40 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 SCT50X100X40S FAQ
This four-position cylinder stops at 0 mm (fully retracted), 40 mm (section two extended), 100 mm (section one extended), and 140 mm (both sections extended, total travel). The positions are discrete and fixed by the two stroke lengths.
An SCT tandem cylinder packages two strokes on a single common rod, reducing mounting space and alignment complexity versus two individual cylinders. It provides up to four fixed stops from a single assembly. However, the force at each stop is the per-section force (982 N push at 0.5 MPa for this 50 mm bore), not a combined force, and the unit requires a mechanical lock or pilot-operated check valve if a position must be held without air pressure.
