About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X25X200S
The SCT50X25X200S tandem cylinder delivers four fixed rod positions—0 mm, 25 mm, 200 mm, and 225 mm total travel—by combining two piston sections on a single 20 mm diameter rod line. Each section generates approximately 982 N of push force at 0.5 MPa, making it suitable for sorting gates or multi-depth pressing operations that require distinct mechanical stops without servo control.
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for end-of-stroke or intermediate position confirmation. The cylinder body has an A(SCT) length of 243 mm, uses PT1/4 ports, and features adjustable air cushioning with a 21 mm cushion length to manage end-of-travel impact.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X25X200S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 25 / 200 mm |
| Total travel | 225 mm |
| Stop positions | 4 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, 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) | 25 mm |
| P2 (section 2) | 200 mm |
| P3 (both extended) | 225 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 SCT50X25X200S Is Used
Two-Lane Part Diverting
Uses the 25 mm and 200 mm positions to direct parts from a single infeed conveyor into two separate outfeed lanes, controlled by pressurizing section one, section two, or both.
Two-Depth Insertion
Provides a shallow 25 mm stop for pre-insertion or staging and a full 225 mm travel for final press-fit, ensuring consistent depth control at both stages.
Multi-Stop Clamping Fixture
Offers retracted, 25 mm, 200 mm, and 225 mm positions for clamping workpieces of varying thicknesses, with sensor feedback at each stop via the integrated magnet.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X25X200S the Right Cylinder?
Choose the SCT tandem configuration when a single actuator must provide multiple fixed stopping points, eliminating the cost and complexity of two separate cylinders with external hard stops. The 25 mm and 200 mm stroke sections create four distinct positions, ideal for diverting parts to two different lanes or operating a two-depth insertion tool. If the 982 N push force per section at 0.5 MPa is marginal for your load, stepping up to the 63 mm bore SCT63 provides 1559 N per section.
For a direct replacement, match the 50 mm bore, both the 25 mm and 200 mm section strokes, the PT port thread, and the built-in magnet (-S suffix). The basic mounting style means no brackets are included, so order FA, FB, CA, CB, or LB mounting kits separately if needed. Note that the 200 mm stroke section is long enough that guiding the rod externally is recommended if the load applies significant side force.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 25 + 200 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 SCT50X25X200S FAQ
It provides four distinct mechanical stop positions: fully retracted (0 mm), the first section extended (25 mm), the second section extended (200 mm), and both sections extended for the total travel of 225 mm. The stops are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, in applications requiring two fixed extension lengths from a single mounting point. It eliminates the need for dual mounting brackets and synchronizing two valves. Ensure the replacement matches the 50 mm bore, 25 mm and 200 mm strokes, PT ports, and the -S magnet option if you are using reed or solid-state sensors.
