About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X160X200S
The SCT50X160X200S is a tandem multi-position pneumatic cylinder that delivers four fixed rod positions from two independently controlled strokes on a single piston rod. With a 50 mm bore and strokes of 160 mm and 200 mm, the reachable stops are 0 mm (fully retracted), 160 mm, 200 mm, and the total travel of 360 mm. Each piston section provides a push force of 982 N at 0.5 MPa, rising to 1767 N at the maximum operating pressure of 0.9 MPa.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for non-contact position feedback. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end ensure smooth deceleration across the full 30-800 mm/s speed range. The body length A(SCT) is 243 mm plus strokes, and the PT1/4 ports are standard.

|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 160 / 200 mm |
| Total travel | 360 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) | 160 mm |
| P2 (section 2) | 200 mm |
| P3 (both extended) | 360 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 SCT50X160X200S Is Used
Two-Lane Part Diverting
Use the 160 mm stroke to position a diverter gate for lane one and the 200 mm stroke for lane two, with the 360 mm total travel clearing a reject chute.
Multi-Depth Press Insertion
Achieve two distinct press depths in one cycle. The 160 mm stroke sets a shallow insertion, and the 200 mm stroke drives to a deeper final seat, controlled by separate valve signals.
Staggered Product Stops
Control the release of products on a gravity conveyor with three stopping gates: fully retracted, a 160 mm first stop, and a 200 mm second stop for timed singulation.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X160X200S the Right Cylinder?
Select this four-position cylinder when your application requires two distinct extended stops beyond the home position, such as a part diverter feeding two separate conveyor lanes. The unequal strokes (160 mm and 200 mm) create unique intermediate positions that would otherwise require two separate cylinders and external hard stops, saving space and simplifying pneumatic circuitry. If a higher force is needed, stepping up to the 63 mm bore provides 1559 N of push per section at the same 0.5 MPa.
For a drop-in replacement, match the 50 mm bore, both the 160 mm and 200 mm strokes, PT port thread, basic mounting, and the -S magnet option. Note that with a combined stroke exceeding 300 mm, consider external guide rods or a linear rail if the rod is subjected to significant side loads to prevent bending of the 20 mm rod.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 160 + 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 SCT50X160X200S FAQ
The four fixed rod positions are 0 mm (fully retracted), 160 mm (section one extended), 200 mm (section two extended), and 360 mm (both sections extended). These are achieved by pressurizing the piston sections individually or simultaneously.
Yes, it is designed to replace two single-rod cylinders used in a back-to-back or tandem arrangement. The replacement must match the 50 mm bore, both 160 mm and 200 mm strokes, PT port thread, and the -S magnet option to ensure identical sensor mounting.
