About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X350X200S
The SCT32X350X200S is a double-acting, multi-position tandem cylinder that delivers four fixed rod positions from two independent piston sections on a single 12 mm rod. The reachable stops are 0 mm (fully retracted), 200 mm, 350 mm, and the combined total travel of 550 mm, selected by pressurising one or both sections. Each 32 mm bore section generates 402 N of push force at 0.5 MPa, scaling to 724 N at the 0.9 MPa maximum operating pressure.
A built-in magnet (denoted by the -S suffix) allows easy external mounting of CMSG, DMSG, or EMSG sensors directly on the tie-rod barrel for non-contact position feedback. The cylinder body length A is 233 mm, and it features an adjustable pneumatic cushion of 21 mm at each end to manage end-of-stroke deceleration. With PT1/8 ports and an M10x1.25 rod thread, this genuine AirTAC unit is suited for compact multi-stop sorting or diverting stations.

| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 350 / 200 mm |
| Total travel | 550 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) | 350 mm |
| P2 (section 2) | 200 mm |
| P3 (both extended) | 550 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 SCT32X350X200S Is Used
4-Position Diverter Gate
Direct packages or components to four separate lanes by extending the rod to 200 mm, 350 mm, or the full 550 mm stroke. The discrete stops ensure repeatable alignment with each conveyor spur.
Multi-Depth Pressing or Staking
Perform two distinct pressing depths in one cycle. Actuate the first section for a 200 mm approach stroke and a light press, then engage the second section to reach the full 550 mm travel for a deeper staking operation.
Staged Part Transfer
Move a workpiece through a three-step process on an assembly line. The rod stops at 200 mm for adhesive dispensing, 350 mm for component placement, and 550 mm for final pick-off, all from a single compact cylinder.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X350X200S the Right Cylinder?
Choose the SCT32X350X200S when your application requires four precise, repeatable mechanical stops without the complexity of servo control or the bulk of two separate cylinders. This tandem design is more compact than pairing an SC32X350 and an SC32X200 with external brackets, and it guarantees the fixed positional relationship between the two strokes. If your load demands higher force, consider stepping up to the SCT40 series, where each section provides 628 N of push at 0.5 MPa.
For a direct replacement, match the 32 mm bore, both the 350 mm and 200 mm section strokes, PT port thread, and the built-in magnet. Since the 350 mm section stroke is relatively long, ensure the rod is adequately guided if significant side loads are present to prevent buckling or uneven seal wear. This model uses a basic mount, so you will need to provide your own mounting interface or select an accessory kit from the FA, FB, CA, CB, or LB range.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 350 + 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 SCT32X350X200S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 200 mm (stroke 2 only), 350 mm (stroke 1 only), and the total combined travel of 550 mm (both sections extended). The positions are fixed by the two section strokes and are not infinitely adjustable.
The force output is per actuated piston section, not a sum of both. Each 32 mm bore section in the SCT32X350X200S delivers 402 N of push force at 0.5 MPa. The tandem design provides multiple positions, not multiplied force. For a higher force requirement, you would need to step up to a larger bore like the SCT40 series.
