Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X50
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X50 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 50mm and 50mm give 3 controllable stop positions across a 100mm total travel, with a Ø63mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X50
The SCT63X50X50 is a double-acting multi-position cylinder that provides three fixed rod positions: fully retracted (0 mm), 50 mm, and 100 mm total travel. Each of its two piston sections generates 1559 N of push force at 0.5 MPa, scaling up to 2805 N at the maximum operating pressure of 0.9 MPa, making it a robust choice for repetitive two-stop indexing tasks.
This 63 mm bore model features a 20 mm diameter rod, PT1/4 ports, and an M16x1.5 rod thread. The body length A(SCT) is 249 mm, and each end incorporates a 28 mm adjustable air cushion to decelerate the load smoothly at both the 50 mm and 100 mm positions.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X50 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X50 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 50 / 50 mm |
| Total travel | 100 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) | 50 mm |
| P2 (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 SCT63X50X50 Is Used
Two-Stop Diverter Gate
Actuates a conveyor diverter to two fixed positions at 50 mm and 100 mm, sorting packages by size or destination code.
Dual-Depth Clamping Fixture
Provides two preset clamping depths for different part families on a machining centre, ensuring rapid changeover between batches.
Staged Material Stop
Positions a material stop at 50 mm for one component length and 100 mm for another in a cut-to-length saw feed system.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X50 the Right Cylinder?
Select the SCT when your application requires two distinct extended positions without the complexity of mounting two separate cylinders and aligning their rods. For lighter loads, the 50 mm bore version provides 982 N of push per section; for heavier pushing requirements, stepping up to the 80 mm bore delivers 2513 N per section. A direct replacement must match the 63 mm bore, both 50 mm strokes, PT port thread, and basic mounting configuration. If a magnetic piston is needed for sensor feedback, specify the -S suffix.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 50 + 50 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 SCT63X50X50 FAQ
This model provides 3 distinct positions because both strokes are equal at 50 mm. The rod stops at 0 mm (retracted), 50 mm (first section extended), and 100 mm (both sections extended).
Yes, it is designed to replace a pair of back-to-back cylinders for two-position work. It ensures inherent rod alignment and reduces plumbing. The replacement must be an AirTAC SCT with a 63 mm bore, both strokes at 50 mm, and matching PT ports.
