About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X30X5S
The SCT63X30X5S is a double-acting multi-position tandem cylinder that delivers four discrete rod positions: 0 mm (fully retracted), 5 mm, 30 mm, and 35 mm (total travel). Each 63 mm bore section generates 1559 N of push force at 0.5 MPa, providing robust pneumatic positioning for short-throw, two-depth operations.
A built-in magnet (-S suffix) allows direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for non-contact position feedback. The cylinder features a 20 mm diameter piston rod with an M16x1.5 thread, PT1/4 ports, and a 28 mm adjustable air cushion, with a body length A(SCT) of 249 mm.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X30X5S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X30X5S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 30 / 5 mm |
| Total travel | 35 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) | 30 mm |
| P2 (section 2) | 5 mm |
| P3 (both extended) | 35 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 SCT63X30X5S Is Used
Two-Stage Part Ejection
Uses the 5 mm stroke for a gentle initial push to break stiction, followed by the full 35 mm extension for complete part ejection from a nest.
Dual-Depth Stamping
Provides a precise 5 mm pre-press position and a 30 mm final forming depth in a compact assembly station, controlled by pressurizing each piston section.
Miniature Gate Diverter
Positions a small diverter gate at 0 mm, 5 mm, or 30 mm to sort lightweight components into three separate chutes on a packaging line.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X30X5S the Right Cylinder?
Select the SCT63X30X5S when an application requires two distinct extended stopping points within a compact 35 mm total stroke envelope. This tandem unit is more cost-effective and mechanically simpler than installing two separate 63 mm bore cylinders with external hard stops to achieve the same 5 mm and 30 mm positions. For a higher thrust requirement, stepping up to the 80 mm bore (SCT80) provides 2513 N of push force per section at 0.5 MPa.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 30 + 5 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 SCT63X30X5S FAQ
This 4-position cylinder provides stops at 0 mm (fully retracted), 5 mm (section 2 extended), 30 mm (section 1 extended), and 35 mm (both sections extended). The positions are fixed and discrete, selected by pressurizing the appropriate air ports.
Yes, if your application needs fixed stops at 5 mm and 30 mm. The SCT tandem design integrates both strokes on a single rod line, saving space and eliminating the need to synchronize two separate cylinders and their external hard stops. Ensure the replacement matches the 63 mm bore, PT1/4 ports, and the built-in magnet for sensor compatibility.
