About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X80X10S
The SCT40X80X10S tandem cylinder delivers four discrete rod positions—0 mm, 10 mm, 80 mm, and the full 90 mm travel—by pressurising its two piston sections independently. Each 40 mm bore section generates 628 N of push force at 0.5 MPa, rising to 1130 N at 0.9 MPa, driven through a 16 mm diameter piston rod.
A built-in magnet (suffix -S) allows direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for end-of-stroke or mid-position confirmation. The body length A is 235 mm, and the adjustable air cushion at each end absorbs impact, supporting speeds up to 800 mm/s.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X80X10S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X80X10S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 80 / 10 mm |
| Total travel | 90 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) | 10 mm |
| P3 (both extended) | 90 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 SCT40X80X10S Is Used
Two-Stage Sorting Gate
Use the 10 mm and 80 mm stops to divert packages onto two separate conveyor lanes from a single actuator, simplifying pneumatic control architecture.
Multi-Depth Insertion
Drive a tooling pin to a shallow 10 mm pre-insertion position, then advance to the full 90 mm depth for two-step assembly processes.
Staggered Part Feeding
Control a feed gate with four distinct openings to meter parts of different heights onto an indexing conveyor without manual adjustment.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X80X10S the Right Cylinder?
Choose the SCT40 when a single cylinder must provide four fixed stops without the complexity of two separate actuators and external hard stops. For higher thrust at the same pressure, step up to the 50 mm bore, which delivers 982 N push per section at 0.5 MPa. This model replaces any AirTAC SCT40X80X10S with the same PT ports, basic mounting, and integrated magnet.
Because the 80 mm section stroke is moderate, standard rod guiding is usually sufficient, but ensure the load is aligned to prevent side-load induced seal wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 80 + 10 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 SCT40X80X10S FAQ
This tandem cylinder provides four discrete positions: fully retracted (0 mm), first section extended (10 mm), second section extended (80 mm), and both sections extended for the total travel of 90 mm.
Yes, the SCT40X80X10S can replace a pair of SC cylinders previously used for two-position indexing, provided the strokes match 80 mm and 10 mm and the total force requirement does not exceed 628 N per section at your operating pressure. Ensure the replacement unit carries the -S magnet if your application uses barrel-mounted sensors.
