About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X25S
The AirTAC SCT63X150X25S is a double-acting multi-position tandem cylinder that delivers four distinct rod positions from a single compact assembly. By pressurizing the two piston sections independently or together, the rod extends to 0 mm (fully retracted), 25 mm, 150 mm, or the total combined travel of 175 mm. This discrete positioning is ideal for sorting, diverting, or two-stage clamping operations.
Each 63 mm bore section generates a pushing force of 1559 N at 0.5 MPa, rising to 2805 N at the maximum operating pressure of 0.9 MPa. The cylinder features a 20 mm diameter piston rod, M16x1.5 rod thread, and PT1/4 ports. An integrated magnet allows for direct mounting of CMSG, DMSG, or EMSG sensors on the 249 mm tie-rod body to confirm each stop position.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X25S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 150 / 25 mm |
| Total travel | 175 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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) | 150 mm |
| P2 (section 2) | 25 mm |
| P3 (both extended) | 175 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 SCT63X150X25S Is Used
Two-Stage Part Diverting
Use the four discrete positions (0, 25, 150, 175 mm) to route parts to different conveyor lanes. A short 25 mm stroke nudges items, while the full 175 mm extension pushes them to a separate line.
Multi-Depth Pressing
Achieve two distinct pressing depths in one cycle. The first section extends 25 mm for a light pre-press, and the second section adds 150 mm for a full-depth forming operation, with sensor confirmation at each step.
Sequential Gate Control
Operate a material gate with three open positions. The rod stops at 25 mm for a trickle feed, 150 mm for a partial open, and 175 mm for a full open, all verified by magnetic sensors on the barrel.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X25S the Right Cylinder?
Select the SCT63X150X25S when your application needs four fixed stopping points without the complexity of two separate cylinders and external hard stops. The tandem design saves space and simplifies pneumatic circuitry compared to a dual-cylinder setup. If your force requirement is lower, stepping down to a 50 mm bore reduces per-section push to 982 N at 0.5 MPa. For a direct replacement, match the 63 mm bore, both the 150 mm and 25 mm strokes, PT port thread, basic mounting, and the -S magnet option. For strokes over 300 mm, consider adding external guides to protect the 20 mm rod from side loads.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 150 + 25 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 SCT63X150X25S FAQ
This tandem cylinder has four discrete rod positions: 0 mm (fully retracted), 25 mm (first section extended), 150 mm (second section extended), and 175 mm (both sections extended for total travel).
The SCT63X150X25S integrates two piston sections on a single rod line, providing four fixed stops in a more compact footprint than two individual cylinders. It simplifies mounting and reduces the number of valves and fittings needed, while delivering the same 1559 N push force per section at 0.5 MPa.
