About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X80S
The SCT32X150X80S is a double-acting multi-position tandem cylinder that delivers four fixed rod positions from two independent piston sections on a common 12mm rod. With strokes of 150mm and 80mm, the reachable stops are 0mm (fully retracted), 80mm, 150mm, and the full 230mm total travel when both sections are pressurised.
A built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for position feedback. Each piston section generates 402N of push force at 0.5MPa, rising to 724N at the maximum 0.9MPa operating pressure. The tie-rod design incorporates a 21mm adjustable air cushion and a compact 233mm body length A(SCT), with PT1/8 ports and an M10x1.25 rod thread.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X80S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 150 / 80 mm |
| Total travel | 230 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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) | 150 mm |
| P2 (section 2) | 80 mm |
| P3 (both extended) | 230 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCT32X150X80S Is Used
Multi-Stop Diverter Gate
Actuates a diverter gate to four distinct positions for sorting packages or materials onto separate conveyor lanes, using the 0, 80, 150, and 230mm stops.
Two-Depth Pressing Station
Provides two distinct pressing depths (80mm and 150mm) plus a full-extension position for part ejection, ideal for light assembly or staking operations.
Staged Part Feeding
Feeds components in a three-step sequence—partial advance to 80mm, full advance to 150mm, and a final push to 230mm—for a progressive machining or insertion process.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X80S the Right Cylinder?
This 32mm bore tandem unit is a space-saving alternative to using two separate cylinders with external stops when a sequence of four positions is needed. If higher force is required, stepping up to the SCT40 bore provides 628N of push per section at 0.5MPa. For a drop-in replacement, match the 32mm bore, both strokes (150mm and 80mm), PT port thread, basic mounting, and the -S magnet option. With a 150mm section stroke, ensure the guided load is supported to prevent rod bending or side-load wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 150 + 80 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 SCT32X150X80S FAQ
It provides four discrete mechanical stops: 0mm (fully retracted), 80mm (section two extended), 150mm (section one extended), and 230mm (both sections extended for total travel).
Yes, it replaces two individual cylinders and external hard stops in applications requiring a fixed sequence of four positions, saving space and simplifying the pneumatic circuit. Ensure the replacement matches the 32mm bore, 150mm and 80mm strokes, PT ports, and magnet sensor option.
