About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X15
The SCT63X40X15 is a tandem multi-position cylinder that provides four distinct rod positions: 0 mm (fully retracted), 40 mm, 15 mm, and the combined total travel of 55 mm. Each piston section generates a push force of 1559 N at 0.5 MPa, offering robust actuation for short-throw, multi-stop tasks. The 20 mm diameter rod and 28 mm air cushion provide stable end-of-stroke deceleration.
Built on a durable tie-rod construction, this 63 mm bore cylinder uses PT1/4 ports and an M16x1.5 rod thread for easy integration. The body length A(SCT) is 249 mm, making it a compact solution for machines that need two different short extension lengths from a single actuator, such as two-depth pressing or part ejection at different clearances.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X15 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X15 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 40 / 15 mm |
| Total travel | 55 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) | 15 mm |
| P3 (both extended) | 55 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 SCT63X40X15 Is Used
Two-Depth Pressing
Achieves a partial press at 15 mm and a full-depth press at 40 mm in assembly fixtures without changing tooling.
Compact Part Sorting
Uses the 15 mm and 40 mm stops to divert small components into two separate chutes from a single feed lane.
Staged Ejection
Ejects a workpiece to a 15 mm clearance for inspection, then a full 40 mm stroke to clear the nest completely.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X15 the Right Cylinder?
Select the SCT63X40X15 when a single actuator must deliver two distinct short strokes, eliminating the complexity and cost of mounting two separate cylinders or using external hard stops. This model is ideal where space is tight but the force requirement is moderate. If your application needs higher force, 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, the exact strokes of 40 mm and 15 mm, PT port thread, and basic mounting configuration.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 40 + 15 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 SCT63X40X15 FAQ
This cylinder has four discrete positions: 0 mm (retracted), 40 mm (first section extended), 15 mm (second section extended), and 55 mm (both sections extended for total travel).
It integrates two strokes on a single common rod line, guaranteeing a fixed spatial relationship between the 15 mm and 40 mm stops. This saves mounting space, reduces alignment complexity, and uses a single set of port connections and flow controls.
