About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X40S
The SCT63X80X40S is a double-acting tandem cylinder that delivers four fixed rod positions from two piston sections on a single rod line. With strokes of 80 mm and 40 mm, the reachable stops are 0 mm (retracted), 40 mm, 80 mm, and the full 120 mm total travel. Each section generates 1559 N of push force at 0.5 MPa, making it suitable for multi-stop sorting or diverting tasks.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors for reliable end-of-stroke or intermediate position detection. The 63 mm bore uses a 20 mm diameter rod with M16x1.5 threads and PT1/4 ports. Adjustable air cushioning at both ends, with a 28 mm cushion length, ensures smooth deceleration across the 30-800 mm/s speed range.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X40S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X40S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 80 / 40 mm |
| Total travel | 120 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) | 80 mm |
| P2 (section 2) | 40 mm |
| P3 (both extended) | 120 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 SCT63X80X40S Is Used
Two-Stage Diverter Gate
Operates a conveyor gate with three open positions plus fully closed, routing packages to four distinct lanes using the 0, 40, 80, and 120 mm stops.
Multi-Depth Pressing
Provides two pressing depths at 40 mm and 120 mm in a compact assembly cell, with a safe retracted home position and an intermediate 80 mm clearance stop.
Staged Part Feeding
Advances components in a stepped fixture, moving first by 40 mm for inspection, then to 80 mm for a secondary operation, and finally to 120 mm for ejection.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X40S the Right Cylinder?
Choose the SCT63X80X40S when your application requires four discrete mechanical stops without the complexity of servo controls or multiple single-stroke cylinders. If you need higher per-section thrust, consider stepping up to the 80 mm bore, which provides 2513 N of push at the same 0.5 MPa. For a direct replacement, match the 63 mm bore, both the 80 mm and 40 mm strokes, PT port thread, basic mounting, and the -S magnet option. With an 80 mm stroke on the first section, ensure the rod is adequately guided if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 80 + 40 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 SCT63X80X40S FAQ
This tandem cylinder provides four distinct mechanical stops: 0 mm (fully retracted), 40 mm, 80 mm, and 120 mm (full extension). The positions are achieved by pressurizing the first, second, or both piston sections.
Yes, it can often replace two single-rod cylinders in applications needing multiple fixed stops on one axis, saving space and simplifying plumbing. Ensure the replacement matches the 63 mm bore, both the 80 mm and 40 mm strokes, PT ports, and the -S magnet sensor option.
