About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X200X500SLB
The SCT100X200X500 is a tandem multi-position cylinder that delivers four discrete rod stops—0 mm, 200 mm, 500 mm, and the combined 700 mm total travel—from a single tie-rod body. Each 100 mm bore section generates 3927 N of push force at 0.5 MPa (rising to 7068 N at 0.9 MPa), driven by a 25 mm diameter rod with PT1/2 ports and a 29 mm air cushion for end-of-stroke deceleration.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and ships with LB foot mounts for stable surface installation. The body length A(SCT) is 308 mm, and the standard TPU seals suit operating temperatures from -20 to +70 °C. The 500 mm section stroke is at the standard limit, so guiding the 25 mm rod is recommended to prevent side-load deflection in horizontal applications.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X200X500SLB Technical Specifications

| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 200 / 500 mm |
| Total travel | 700 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/2 |
| 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, 29 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) | 200 mm |
| P2 (section 2) | 500 mm |
| P3 (both extended) | 700 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SCT100X200X500SLB Is Used
Four-Position Diverter Gate
Direct packages or pallets to four separate conveyor lanes by pressurising section one, section two, or both, achieving precise stops at 0, 200, 500, and 700 mm.
Multi-Depth Pressing Station
Control a platen to two distinct pressing depths (200 mm and 500 mm) plus a full-extension 700 mm clearance position, all from one compact tandem cylinder.
Staged Part Feeding
Advance components in three controlled steps—200 mm, 500 mm, and 700 mm—for a progressive assembly or machining process, using the LB foot mounts for rigid inline mounting.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X200X500SLB the Right Cylinder?
Choose the SCT100X200X500 when a single actuator must index between four fixed positions without the complexity of two separate cylinders and external hard stops. For lighter loads, stepping down to an 80 mm bore reduces per-section push force to 2513 N at 0.5 MPa, while the 100 mm bore provides the maximum force in the SCT range. This tandem unit replaces any AirTAC SCT100 with 200 mm and 500 mm section strokes, PT ports, LB mounting, and a magnet sensor option.
Because the second stroke section extends to 500 mm, ensure the rod is externally guided or the load is centrally aligned to prevent bending moments, especially when the rod is fully extended to the 700 mm combined position.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 200 + 500 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 SCT100X200X500SLB FAQ
It provides four discrete mechanical stops: fully retracted (0 mm), first section extended (200 mm), second section extended (500 mm), and both sections extended (700 mm total travel). The positions are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, it directly replaces a setup using two individual SC100 cylinders with 200 mm and 500 mm strokes where you need the three extended positions on one rod line. Ensure the replacement matches the 100 mm bore, PT1/2 ports, LB foot mounting, and the -S magnet option for sensor compatibility.
