About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X10
The SCT63X150X10 is a double-acting multi-position tandem cylinder that provides four fixed rod positions: fully retracted (0 mm), 10 mm, 150 mm, and the total extended travel of 160 mm. Each 63 mm bore piston 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 tasks requiring two distinct short-throw and long-throw stops in a single compact unit.
This tie-rod cylinder uses a 20 mm diameter piston rod with M16x1.5 threads and PT1/4 ports. The adjustable pneumatic cushion at each end is 28 mm long, and the body length A(SCT) is 249 mm. The standard TPU seals and PT threads suit general industrial environments operating between -20 and +70 °C.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X10 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X10 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 150 / 10 mm |
| Total travel | 160 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) | 150 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 160 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 SCT63X150X10 Is Used
Two-Stage Sorting Gate
Uses the 10 mm stop for a partial gate opening to separate small parts and the 150 mm stop for full flow diversion, all from one cylinder body.
Dual-Depth Labeling
Applies labels at two different heights on a product by moving to the 10 mm and 150 mm positions, eliminating the need for a two-axis slide.
Multi-Step Clamping
Provides a low-force 10 mm pre-clamp position followed by a full 150 mm high-force clamping stroke, protecting delicate assemblies from initial impact.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X10 the Right Cylinder?
Choose the SCT63X150X10 when your process needs two separate stop positions—a precise 10 mm advance and a longer 150 mm stroke—without installing two individual cylinders and external hard stops. If the 1559 N push force per section at 0.5 MPa is insufficient, stepping up to the 80 mm bore provides 2513 N per section; for a lighter load, the 50 mm bore offers 982 N per section. A direct replacement must match the 63 mm bore, both 150 mm and 10 mm strokes, PT port thread, and basic mounting configuration.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 150 + 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 SCT63X150X10 FAQ
This tandem cylinder has four discrete positions: 0 mm (fully retracted), 10 mm (first section extended), 150 mm (second section extended), and 160 mm (both sections extended for total travel).
No, it does not have a mechanical lock. If the air pressure is lost or the valve is centered, the piston rod can drift. You must add an external rod brake or pilot-operated check valve to hold the load at any intermediate position without live pressure.
