About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X70X30S
The SCT32X70X30S creates four fixed rod positions—0 mm, 70 mm, 30 mm, and 100 mm—by sequencing air to its two tandem piston sections. With a 12 mm rod and PT1/8 ports, each section delivers 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 band around the piston allows CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position feedback. The 21 mm adjustable air cushion at each end decelerates the load smoothly, making this genuine AirTAC unit a precise pick for light sorting or diverting tasks.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X70X30S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X70X30S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 70 / 30 mm |
| Total travel | 100 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) | 70 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 100 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 SCT32X70X30S Is Used
Two-Way Part Diverting
Uses the 70 mm and 30 mm stroke positions to guide parts into separate chutes from a single feed lane, with the 100 mm total travel clearing the junction.
Multi-Depth Pressing
Provides two controlled insertion depths (30 mm and 70 mm) for assembly processes requiring a light touch at one station and full seating at the next.
Staged Ejector
The 0, 30, 70, and 100 mm stops allow a single cylinder to park a reject mechanism at a safe home, a partial-eject warning position, and a full-eject stroke.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X70X30S the Right Cylinder?
Choose the SCT32X70X30S when your sequence needs four distinct stop points without the complexity of two separate cylinders and external stops. The 70 mm and 30 mm strokes give asymmetric reach, ideal for a two-depth insertion or a diverting gate with unequal travel. If the 402 N push per section is marginal, stepping up to the 40 mm bore provides 628 N at the same pressure.
For a drop-in replacement, match the 32 mm bore, both strokes (70 mm and 30 mm), PT port thread, and the -S magnet option. The basic mount suits direct machine-face attachment, but FA or LB bracketry can be added if the mounting pattern changes.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 70 + 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 SCT32X70X30S FAQ
It provides 4 discrete mechanical stops: fully retracted (0 mm), first section extended (70 mm), second section extended (30 mm), and both sections extended for the total travel of 100 mm.
Yes, if your sequence requires the 0, 30, 70, and 100 mm positions. It eliminates the need to synchronize two cylinders and their mountings, but the force remains 402 N per actuated section, not a combined 804 N.
