About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X60S
The AirTAC SCT63X40X60S is a double-acting tandem cylinder that delivers four fixed rod positions from two independent piston sections: 0 mm, 40 mm, 60 mm, and the combined 100 mm total travel. Each 63 mm bore section generates 1559 N of push force at 0.5 MPa, rising to 2805 N at the maximum operating pressure of 0.9 MPa, making it suitable for sorting or diverting tasks requiring multiple mechanical stops.
This model includes a factory-installed magnetic piston, designated by the -S suffix, allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position feedback. The 20 mm diameter piston rod and M16x1.5 rod-end thread provide robust guidance, while the 28 mm adjustable air cushion at each end decelerates the load smoothly across all four stop positions.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X60S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X60S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 40 / 60 mm |
| Total travel | 100 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) | 40 mm |
| P2 (section 2) | 60 mm |
| P3 (both extended) | 100 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 SCT63X40X60S Is Used
Two-Lane Diverter Gate
Uses the 40 mm and 60 mm stops to align a chute or gate with two separate conveyor lanes, directing product flow based on the pressurised section combination.
Dual-Depth Pressing
Provides a partial-engage position at 40 mm for alignment and a full-depth press at 100 mm, with the 60 mm stop serving as an intermediate forming stage.
Multi-Stop Part Transfer
Shifts a workpiece through four distinct stations on a linear transfer line, using the fixed rod positions to align with different tooling or pick-and-place heads.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X60S the Right Cylinder?
Selecting the SCT63X40X60S is ideal when a single actuator must replace two separate cylinders or an SC unit with external hard stops to achieve a four-position sequence. The discrete 40 mm and 60 mm strokes allow for asymmetric extension and retraction movements without complex valving. If higher force is needed, stepping up to the 80 mm bore provides 2513 N of push per section at the same pressure. For a direct replacement, match the 63 mm bore, both the 40 mm and 60 mm section strokes, PT port thread, basic mounting, and the -S magnet option.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 40 + 60 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 SCT63X40X60S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 40 mm, 60 mm, and the combined total travel of 100 mm. These are selected by pressurising the first, second, or both piston sections.
To ensure identical fit and function, the replacement must be an AirTAC SCT series cylinder with a 63 mm bore, 40 mm first stroke, 60 mm second stroke, PT ports, basic mounting, and the -S magnet option for sensor compatibility.
