About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X120X60
The SCT63X120X60 is a double-acting multi-position cylinder that provides four distinct rod positions: 0 mm, 60 mm, 120 mm, and the full combined travel of 180 mm. Each piston section delivers a push force of 1559 N at 0.5 MPa, driven through a 20 mm diameter rod with PT1/4 ports and a 28 mm adjustable air cushion for smooth end-of-stroke deceleration.
With a body length A of 249 mm, this tandem unit replaces two separate cylinders and external stops in a single tie-rod assembly. It is suited for sorting gates or two-depth pressing where three intermediate positions are required between full retract and full extend.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X120X60 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X120X60 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 120 / 60 mm |
| Total travel | 180 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) | 120 mm |
| P2 (section 2) | 60 mm |
| P3 (both extended) | 180 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 SCT63X120X60 Is Used
Two-Stage Diverter
Uses the 60 mm and 120 mm stops to route packages to two separate conveyor lanes from a single infeed point.
Multi-Depth Press
Provides two distinct pressing depths (60 mm and 180 mm) for assembling components with different insertion lengths.
Staged Part Feeding
Advances parts in two increments, first a 60 mm push for separation, then a further 120 mm stroke to load the nest.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X120X60 the Right Cylinder?
Choose the SCT63X120X60 when your application requires four fixed stop points without the complexity of multiple actuators. If a higher per-section force is needed, stepping up to the 80 mm bore provides 2513 N of push at the same pressure. For replacement, match the 63 mm bore, both strokes of 120 mm and 60 mm, PT thread, and basic mounting. Ensure the load is guided if the combined 180 mm stroke creates a moment arm on the rod.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 120 + 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 SCT63X120X60 FAQ
It has four discrete mechanical stops: 0 mm (fully retracted), 60 mm (first section extended), 120 mm (second section extended), and 180 mm (both sections extended).
Yes, it is designed to replace a setup with two individual cylinders and external hard stops. It provides the same 1559 N push force per section at 0.5 MPa in a single, compact tie-rod body.
