About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X80
The SCT63X80X80 is a double-acting tandem cylinder that delivers three fixed rod positions: fully retracted (0 mm), 80 mm, and the combined 160 mm total travel. Each 63 mm bore section generates a push force of 1559 N at 0.5 MPa, rising to 2805 N at the maximum operating pressure of 0.9 MPa, making it suitable for medium-duty sorting and diverting tasks.
This model features a 20 mm diameter piston rod and PT1/4 ports, with an adjustable air cushion length of 28 mm at each end to decelerate the load smoothly. The body length A(SCT) is 249 mm, providing a compact tandem assembly for its 160 mm total stroke.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X80 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X80 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 80 / 80 mm |
| Total travel | 160 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) | 80 mm |
| P2 (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 SCT63X80X80 Is Used
Two-Position Diverter Gate
Actuates a gate to three distinct positions for routing packages on a conveyor line: home, mid-stroke bypass at 80 mm, and full extension at 160 mm for the primary lane.
Multi-Stop Part Feeding
Advances a pusher block to two precise stops beyond the retracted position, staging components at 80 mm and 160 mm for sequential pick-and-place operations.
Two-Depth Pressing Station
Provides a pre-press position at 80 mm and a final pressing depth at 160 mm, controlled by pressurizing the first or both cylinder sections in a simple assembly fixture.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X80 the Right Cylinder?
Choose the SCT63X80X80 when an application requires a 63 mm bore with three positive mechanical stops, eliminating the complexity of two separate cylinders and external hard stops. If the load demands a higher force class, stepping up to the 80 mm bore SCT80X80X80 provides 2513 N of push per section at 0.5 MPa. For a direct replacement, match the 63 mm bore, both 80 mm section strokes, PT port thread, and basic mounting type exactly.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 80 + 80 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 SCT63X80X80 FAQ
This tandem cylinder provides three discrete mechanical stops: 0 mm (fully retracted), 80 mm (first section extended), and 160 mm (both sections extended). The positions are fixed by the two 80 mm strokes and are not infinitely adjustable.
Yes, it is designed to replace two individually mounted 63 mm bore cylinders with 80 mm strokes that were used to achieve three positions. Ensure the replacement matches the 63 mm bore, both 80 mm strokes, PT port thread, and basic mounting configuration.
