About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X230X415S
The SCT80X230X415S is a double-acting multi-position cylinder that delivers four fixed rod positions from two independent piston sections on a common rod line. With strokes of 230 mm and 415 mm, the reachable stops are 0 mm (fully retracted), 230 mm, 415 mm, and the combined total travel of 645 mm. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for non-contact position feedback at each stop.
Each 80 mm bore section generates 2513 N of push force at 0.5 MPa, rising to 4523 N at the maximum operating pressure of 0.9 MPa. The 25 mm diameter rod and 28 mm adjustable air cushion at each end provide smooth deceleration across the 30-800 mm/s speed range. The body length A(SCT) is 296 mm, and the standard PT3/8 port threads ensure straightforward pneumatic integration.

| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 230 / 415 mm |
| Total travel | 645 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) | 230 mm |
| P2 (section 2) | 415 mm |
| P3 (both extended) | 645 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 SCT80X230X415S Is Used
Four-Position Diverter Gate
Controls a conveyor diverter gate to four distinct positions for sorting packages to different lanes, using the 0, 230, 415, and 645 mm stops.
Multi-Depth Pressing Station
Provides three pressing depths plus a retracted home position in a single stroke sequence, ideal for progressive forming or insertion operations.
Staged Part Transfer
Moves a workpiece through four fixed stations on an assembly line with a single actuator, eliminating the need for a servo-driven slide for discrete indexing.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X230X415S the Right Cylinder?
This 4-position tandem cylinder replaces complex setups that would otherwise require two separate cylinders with external hard stops and sequencing valves. The SCT80X230X415S provides the discrete stops in a single, compact tie-rod assembly, simplifying mounting and reducing the number of air connections. When selecting, verify that the 2513 N per-section push force at 0.5 MPa matches the load requirement; if a lighter force profile is acceptable, the 63 mm bore SCT offers 1559 N per section at the same pressure. For a direct replacement, match the 80 mm bore, both the 230 mm and 415 mm section strokes, the PT3/8 port thread, and the integrated magnet (-S suffix). Given the 415 mm section stroke, ensure the rod is externally guided if the load applies significant side force or the cylinder is mounted horizontally to prevent rod deflection and premature seal wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 230 + 415 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 SCT80X230X415S FAQ
This tandem cylinder provides 4 discrete mechanical stop positions. The rod can be positioned at 0 mm (fully retracted), 230 mm (first section extended), 415 mm (second section extended), and 645 mm (both sections extended for total travel).
Yes, it is designed to replace two individually mounted cylinders that were used with external stops to achieve multiple positions. For a direct form-and-fit replacement, ensure the alternative setup matches the 80 mm bore, the 230 mm and 415 mm stroke lengths, the PT3/8 pneumatic ports, and the -S magnet option for sensor compatibility.
