Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X600S
The AirTAC Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X600S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 100mm and 600mm give 4 controllable stop positions across a 700mm total travel, with a Ø100mm bore, PT1/2 ports and adjustable end cushioning.

About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X600S
The SCT100X100X600S tandem cylinder provides four distinct rod positions—0 mm, 100 mm, 600 mm, and full 700 mm extension—using two independently controllable piston sections on a single 25 mm rod. With 3927 N of push force per section at 0.5 MPa, it handles heavy multi-stop indexing tasks without the complexity of dual-cylinder setups.
A built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke or mid-position detection. The 100 mm bore body has a 308 mm base length and 29 mm adjustable air cushion, while the 600 mm section stroke is made-to-order, extending lead time slightly for this non-standard configuration.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X600S Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X600S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 100 / 600 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). This configuration exceeds the 500 mm standard section stroke, so it is a non-standard / made-to-order build. 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) | 600 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 SCT100X100X600S Is Used
Two-Stage Clamping
Partially extends 100 mm for low-force pre-clamp, then drives full 600 mm for high-pressure final forming, with sensor confirmation at each position.
Long-Stroke Sorting Gate
Uses the 100 mm stop for diverting small parts and the 700 mm total travel to sweep larger items onto a separate conveyor lane.
Dual-Depth Assembly Press
Installs a bushing at 100 mm depth, then a second component at 700 mm in one smooth, position-verified machine cycle.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X100X600S the Right Cylinder?
This SCT model suits applications needing a short 100 mm advance and a long 600 mm secondary feed from one compact tie-rod assembly. If your cycle requires higher thrust, stepping up is not possible as 100 mm is the largest SCT bore; for lower force, the SCT80X100X600S offers 2513 N push per section. When replacing, match the 100 mm bore, both 100 mm and 600 mm strokes, PT ports, and the -S magnet suffix to retain sensor functionality.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 600 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 SCT100X100X600S FAQ
This tandem cylinder provides four discrete rod positions: fully retracted (0 mm), first section extended (100 mm), second section extended (600 mm), and both sections extended (700 mm total).
Yes, the -S suffix means a magnet is built into the piston, making it fully compatible with AirTAC CMSG, DMSG, and EMSG reed or solid-state sensors that clamp directly onto the tie-rod barrel.
