About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X80X100S
The SCT40X80X100S creates four fixed rod positions—0 mm, 80 mm, 100 mm, and 180 mm total travel—by combining two piston sections on a single 16 mm rod. Each section delivers about 628 N of push force at 0.5 MPa, making it a compact alternative to two separate actuators for sequenced stops.
A built-in magnet lets CMSG, DMSG, or EMSG sensors clamp directly to the tie-rod barrel for non-contact position sensing. With a 21 mm adjustable air cushion and a body length of 235 mm plus strokes, it fits neatly into multi-step feeding or diverting stations.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X80X100S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X80X100S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 80 / 100 mm |
| Total travel | 180 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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) | 80 mm |
| P2 (section 2) | 100 mm |
| P3 (both extended) | 180 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SCT40X80X100S Is Used
3-Way Diverter Gate
Positions 0, 80, and 180 mm align a chute to three separate conveyor lanes, driven by two valves.
Two-Depth Pressing
Stroke 1 (80 mm) pre-forms material; stroke 2 (100 mm) applies final compaction at 180 mm total travel.
Multi-Stop Indexing
A stop pin extends to 80 mm for one pallet size and 100 mm for another, retracting fully to 0 mm for bypass.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X80X100S the Right Cylinder?
This 4-position unit replaces two individual cylinders or an SC with external hard stops when you need three intermediate positions plus home. If higher force is required, step up to the 50 mm bore SCT, which provides 982 N push per section at 0.5 MPa. For a direct replacement, match the 40 mm bore, both 80 mm and 100 mm strokes, PT ports, and the -S magnet option. Consider external guides if the combined 180 mm stroke creates a side-load risk.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 80 + 100 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 SCT40X80X100S FAQ
It provides four discrete rod positions: fully retracted (0 mm), first section extended (80 mm), second section extended (100 mm), and both sections extended (180 mm).
Each piston section generates 628 N pushing and 528 N pulling at 0.5 MPa. At the maximum operating pressure of 1.0 MPa, the theoretical push force per section is 128 kgf.
