About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X3X10S
The SCT80X3X10S is an 80 mm bore tandem multi-position cylinder that delivers four fixed rod positions: 0 mm (fully retracted), 3 mm, 10 mm, and the combined total travel of 13 mm. Each piston section generates 2513 N of push force at 0.5 MPa, providing robust pneumatic actuation for short, precise indexing tasks.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position sensing. The 25 mm diameter piston rod and 28 mm air cushion length ensure smooth deceleration at each end of the 13 mm total stroke, enhancing cycle life in high-speed sorting operations.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X3X10S Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X3X10S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 3 / 10 mm |
| Total travel | 13 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| 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, 28 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) | 3 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 13 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SCT80~100 Multi-Position Tandem Cylinder SCT80X3X10S Is Used
Precision Shimming & Gauging
Achieves two distinct gauging depths (3 mm and 10 mm) or a combined 13 mm pass-through position for automated quality control checks on small components.
Micro-Part Sorting Gate
Uses the four discrete rod positions to direct miniature parts into three separate chutes or bins from a single feed lane, controlled by pressurizing each cylinder section.
Multi-Level Staking Press
Provides two controlled staking depths (3 mm and 10 mm) plus a full-retract and full-forward position for assembling delicate electronic connectors without overtravel.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X3X10S the Right Cylinder?
Select the SCT80X3X10S when your application requires four distinct, repeatable stop positions within a very compact 13 mm total stroke envelope, eliminating the complexity of two separate short-stroke cylinders and external hard stops. If higher force per section is needed, consider stepping up to the 100 mm bore SCT100 series, which provides 3927 N of push at 0.5 MPa. For a direct replacement, match the 80 mm bore, both the 3 mm and 10 mm section strokes, PT port thread, basic mounting, and the -S magnet option.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 3 + 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 SCT80~100 Multi-Position Tandem Cylinder SCT80X3X10S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 3 mm (section one extended), 10 mm (section two extended), and 13 mm (both sections extended). The positions are fixed by the internal piston strokes and are not infinitely adjustable.
Yes. The -S suffix designates a built-in magnet along the barrel. This allows you to attach AirTAC CMSG, DMSG, or EMSG reed or solid-state sensors directly to the cylinder body to confirm arrival at each of the four discrete positions.
