About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X60X10S
The SCT63X60X10S is a tandem multi-position pneumatic cylinder that provides four fixed rod positions: fully retracted (0 mm), first section extended (60 mm), second section extended (10 mm), and both sections extended for a total travel of 70 mm. This unequal stroke configuration is ideal for applications requiring a primary long travel with a secondary short positioning step, such as a two-depth pressing operation or a diverter gate with a fine-adjustment stage.
Each piston section delivers 1559 N of push force at 0.5 MPa, rising to 2805 N at the maximum operating pressure of 0.9 MPa. The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG sensors on the 63 mm bore tie-rod barrel for precise end-of-stroke or mid-position detection. The unit uses a 20 mm diameter rod with M16x1.5 male threads, PT1/4 ports, and a 28 mm adjustable air cushion on each section to decelerate the load smoothly.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X60X10S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 60 / 10 mm |
| Total travel | 70 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) | 60 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 70 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 SCT63X60X10S Is Used
Two-Depth Pressing
Uses the 60 mm stroke for rapid approach and the 10 mm stroke for a controlled final press depth, ensuring consistent part insertion or forming.
3-Way Diverter Gate
Retracted (0 mm) for lane one, 60 mm for lane two, and 70 mm total extension for lane three, with the 10 mm position serving as a setup or cleaning stop.
Staged Clamping
Applies an initial 60 mm travel to contact the workpiece, then a short 10 mm power stroke to build full clamping force, verified by the magnetic sensor.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X60X10S the Right Cylinder?
Choose the SCT63X60X10S when a single cylinder must provide two independent, repeatable stop positions without the complexity of dual cylinders and external hard stops. The 60 mm and 10 mm stroke combination is a made-to-order configuration, offering a tailored solution for machinery where a primary 60 mm movement is followed by a precise 10 mm advance. If higher force is required, consider stepping up to the 80 mm bore, which provides 2513 N of push per section at 0.5 MPa.
For direct replacement, match the 63 mm bore, the exact 60 mm and 10 mm strokes, PT port thread, and the -S magnet option. The basic mounting configuration accepts standard SCT foot (LB) or flange (FA/FB) accessories if the mounting style needs to change later. Note that the 60 mm stroke section is relatively short, so rod side-loading is minimal, but always align the load axially to preserve seal life.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 60 + 10 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 SCT63X60X10S FAQ
It provides four distinct mechanical stop positions: 0 mm (fully retracted), 60 mm (first section extended), 10 mm (second section extended), and 70 mm (both sections extended, which is the total travel). The unequal strokes create two intermediate positions plus full extension.
Yes, in many cases it can. A single SCT tandem unit with 60 mm and 10 mm strokes replaces two individually mounted cylinders and their external stop hardware, reducing plumbing and mounting complexity. Ensure the replacement matches the 63 mm bore, both stroke lengths, PT1/4 ports, and the -S magnet option if sensor feedback is required.
