About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X75S
The SCT32X100X75S is a genuine AirTAC multi-position tandem cylinder that delivers four discrete rod stops from two strokes on a single tie-rod body. Its 12 mm diameter rod reaches exactly 0 mm (retracted), 100 mm, 75 mm, and 175 mm total travel, giving designers a compact way to handle three advanced positions plus home without extra actuators.
Each piston section produces 402 N of push force at 0.5 MPa (563 N at 0.7 MPa), and the built-in magnet lets CMSG, DMSG or EMSG sensors mount directly on the barrel for end-of-stroke or mid-position confirmation. The body length A(SCT) is 233 mm, and the 21 mm air cushion at each end protects the assembly during high-cycle moves.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X75S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X75S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 100 / 75 mm |
| Total travel | 175 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) | 100 mm |
| P2 (section 2) | 75 mm |
| P3 (both extended) | 175 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 SCT32X100X75S Is Used
Two-Lane Diverter Gate
Uses the 100 mm and 75 mm stops to route packages into separate conveyor lanes, with the magnet confirming each gate position before the next cycle.
Multi-Depth Label Press
Applies labels at two controlled depths—100 mm for rigid containers and 75 mm for flexible pouches—while the home sensor at 0 mm signals ready-to-load status.
Staged Component Ejector
Advances a pusher to 100 mm for primary ejection, retracts to the 75 mm intermediate stop for a secondary part, then returns home, all verified by barrel-mounted sensors.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X75S the Right Cylinder?
This four-stop SCT model is ideal when a sequence needs two different working positions beyond the home stop—for instance, a diverter gate that parks at 100 mm for lane A and 75 mm for lane B. If the 402 N per-section push is marginal, stepping up to the SCT40 series raises it to 628 N at the same pressure. For direct replacement, match the 32 mm bore, both 100 mm and 75 mm strokes, PT ports, and the -S magnet option; mounting is basic, so the cylinder drops into the same footprint as the original.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 75 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 SCT32X100X75S FAQ
It provides four distinct rod positions: 0 mm (fully retracted), 100 mm (first section extended), 75 mm (second section extended), and 175 mm (both sections extended). The unequal strokes create four usable stops.
Yes, if your sequence needs exactly the 0, 100, 75 and 175 mm stops. The SCT32X100X75S replaces two separate 32 mm bore cylinders and their mounting hardware with one tandem body, reducing air plumbing and saving space. Ensure the replacement matches the 32 mm bore, both stroke lengths, PT ports, and the -S magnet if sensors are used.
