About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X10S
The SCT63X10X10S is a double-acting multi-position cylinder that provides three fixed rod positions: fully retracted (0 mm), first section extended (10 mm), and both sections extended for a total travel of 20 mm. Each piston section delivers 1559 N of push force at 0.5 MPa, rising to 2805 N at 0.9 MPa, driven through a 20 mm diameter rod.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for precise end-of-stroke or mid-position confirmation. The 63 mm bore body has a length of 249 mm and uses PT1/4 ports, making it a compact yet powerful solution for short-throw, multi-stop tasks.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X10S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X10S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 10 / 10 mm |
| Total travel | 20 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 10 mm |
| P2 (both extended) | 20 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 SCT63X10X10S Is Used
Two-Stage Sorting Gate
Uses the 10 mm and 20 mm positions to divert parts into three separate chutes in a compact sorting station, with sensor feedback confirming gate alignment at each stop.
Micro-Stop Assembly Press
Provides a retracted, partial-advance, and full-advance position for a pressing tool, enabling a two-depth insertion sequence with 2805 N of force at 0.9 MPa.
Multi-Lane Diverter
Controls a blade across a conveyor to direct products to lane A (10 mm stroke) or lane B (20 mm total travel), with the magnet confirming the blade's exact position.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X10X10S the Right Cylinder?
Choose the SCT63X10X10S when a single cylinder must provide three distinct mechanical stops without the complexity of two separate actuators and external hard stops. For higher force requirements in the same form factor, stepping up to the 80 mm bore provides 2513 N of push per section at 0.5 MPa. This cylinder is a direct replacement for another AirTAC SCT63 with 10 mm and 10 mm strokes, PT thread, and a basic mount, provided the magnet sensor option is required.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 10 + 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 SCT63X10X10S FAQ
It provides 3 discrete mechanical stop positions: 0 mm (fully retracted), 10 mm (first section extended), and 20 mm (both sections extended). These stops are fixed by the two 10 mm strokes and are selected by pressurising the appropriate cylinder sections.
Yes, it is designed to replace a pair of back-to-back cylinders for a compact three-position application. It matches the bore and stroke of two SC63x10 units but in a single tandem body. Ensure the porting, PT thread, and the required sensor magnet (-S) match your existing setup.
