Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X130S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X130S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 80mm and 130mm give 4 controllable stop positions across a 210mm total travel, with a ร50mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X130S
The SCT50X80X130S is a tandem multi-position cylinder that delivers four fixed rod positions from two independent strokes on a single axis. By pressurising the 80 mm section, the 130 mm section, or both together, the rod reaches exactly 0, 80, 130, or 210 mm of travel without external hard stops.
Each 50 mm bore piston section generates 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa), driven through a 20 mm diameter rod. The built-in magnet allows CMSG/DMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. A 21 mm air cushion at each end decelerates the load smoothly.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X130S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | ร50 mm |
| Stroke 1 / Stroke 2 | 80 / 130 mm |
| Total travel | 210 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16ร1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 โ 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 โ 800 mm/s |
| Cushion | Adjustable, 21 mm |
| Max stroke / section | Up to 500 mm standard |
Specifications follow the official AirTAC SCT (multi-position) datasheet. SCT is available in bores 32โ100; 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) | 130 mm |
| P3 (both extended) | 210 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 (ร50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | โ |
| Max (@1.0 MPa) | 200 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 SCT50X80X130S Is Used
Two-Stage Part Diverting
The 80 mm stroke shifts a diverter gate to lane A, while the 130 mm stroke reaches lane B. Both sections pressurised sends product to lane C, giving a compact three-lane sorting station from one cylinder.
Multi-Depth Press Insertion
Use the 80 mm stop for a shallow pre-press alignment and the 130 mm stop for a deeper seating depth. The full 210 mm travel ejects the finished assembly, all with repeatable pneumatic positioning.
Sequential Clamping & Forming
In a bending fixture, the first 80 mm stroke applies a light clamp, the 130 mm stroke performs the primary bend, and the combined 210 mm stroke over-travels for springback compensation before retracting.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X80X130S the Right Cylinder?
Choose the SCT when a process needs three or four fixed stop points but only one pneumatic axis. The 80 mm and 130 mm strokes give asymmetric positions ideal for a two-step feed followed by a full-extend eject. If the 982 N push per section is too light, stepping up to the 63 mm bore provides 1559 N per section at the same pressure.
For drop-in replacement, match the 50 mm bore, both 80 mm and 130 mm strokes, PT port thread, basic mounting, and the -S magnet option. When a section stroke exceeds 300 mm, add an external guide to protect the 20 mm rod from side-load bending.
Multi-position checklist
- โ Need 4 repeatable stops?
- โ Section strokes 80 + 130 mm suit your layout?
- โ Required force at your working pressure
- โ Port/thread type (PT/NPT/G)
- โ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 โ 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 SCT50X80X130S FAQ
It provides four discrete mechanical stops: 0 mm (fully retracted), 80 mm (section one extended), 130 mm (section two extended), and 210 mm (both sections extended, the total of 80+130 mm). The positions are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, it is designed to replace two single-rod cylinders mounted back-to-back. The SCT50X80X130S provides the same four-stop functionality in one compact, aligned assembly. Ensure the replacement matches the 50 mm bore, 80 mm and 130 mm strokes, PT ports, and the -S magnet if sensors are used.
