Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X65X30S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X65X30S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 65mm and 30mm give 4 controllable stop positions across a 95mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X65X30S
The SCT32X65X30S tandem cylinder delivers four discrete rod positions—0 mm, 30 mm, 65 mm, and 95 mm—from two independent piston sections on a single 12 mm rod. Each section generates 402 N of push force at 0.5 MPa, making it a compact solution for light-duty sorting or diverting tasks where multiple mechanical stops are needed.
A built-in magnet allows CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for end-of-stroke or intermediate position confirmation. The body length A is 233 mm with a 21 mm adjustable air cushion at each end, and the PT1/8 ports keep the footprint small for integration into tight machine envelopes.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X65X30S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X65X30S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 65 / 30 mm |
| Total travel | 95 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) | 65 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 95 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 SCT32X65X30S Is Used
Multi-Stop Diverter Gate
Positions a diverter flap at 0°, 30°, 65°, or 95° of linear travel to route packages down four separate conveyor lanes from one infeed point.
Two-Depth Label Applicator
Extends a tamp pad to 30 mm for shallow containers or 95 mm for deep cartons, with a 65 mm intermediate position for mid-sized products, all from one compact actuator.
Staged Part Ejection
Pushes rejected parts off a line at 65 mm for a side chute or 95 mm for a rear bin, while the 30 mm position provides a gentle nudge for repositioning without ejection.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X65X30S the Right Cylinder?
Choose the SCT32X65X30S when a single cylinder must provide four fixed stop points without the complexity of two separate actuators and external hard stops. If the 402 N push force per section is marginal, stepping up to the SCT40 series provides 628 N per section at the same 0.5 MPa pressure. For direct replacement, match the 32 mm bore, both strokes (65 mm and 30 mm), PT thread, and the built-in magnet; this model uses a basic mount, so any mounting brackets must be ordered separately if needed.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 65 + 30 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 SCT32X65X30S FAQ
The rod stops at four discrete positions: fully retracted (0 mm), 30 mm, 65 mm, and the total travel of 95 mm. These are fixed by the two section strokes and selected by pressurizing section one, section two, or both simultaneously.
Yes, in applications requiring three or four fixed mechanical stops. The SCT32X65X30S provides the same 402 N push force per section as a standard SC32 but integrates both strokes on one rod line, saving space and eliminating the need to synchronize two separate actuators.
