Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X20X30
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X20X30 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 20mm and 30mm give 4 controllable stop positions across a 50mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X20X30
The SCT32X20X30 tandem cylinder delivers four distinct rod positions—0, 20, 30, and 50 mm—by combining two piston sections on a single 12 mm rod. This configuration is ideal for compact machines that need to shuttle, sort, or stop at multiple points without extra actuators.
Each section provides 402 N of push force at 0.5 MPa (563 N at 0.7 MPa), and the body uses a 21 mm air cushion for smooth end-of-stroke deceleration. The PT1/8 ports and M10x1.25 rod thread keep the envelope small for tight installations.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X20X30 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X20X30 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 20 / 30 mm |
| Total travel | 50 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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, 21 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) | 20 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 50 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCT32X20X30 Is Used
Two-Way Sorting Gate
Diverts parts to two different conveyor lanes using the 20 mm and 50 mm extended positions, with the 30 mm stop as a buffer.
Multi-Stop Feeding
Advances components to three separate workstations in sequence, eliminating the need for multiple short-stroke cylinders.
Two-Depth Pressing
Applies a light touch at 20 mm and full insertion force at 50 mm, with the 30 mm position used for part ejection.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X20X30 the Right Cylinder?
Choose the SCT32X20X30 when you need four fixed stops in a space that cannot fit two separate cylinders. If your load requires more thrust, step up to the 40 mm bore, which delivers 628 N per section at the same pressure. For direct replacement, match the 32 mm bore, both 20 and 30 mm strokes, PT port thread, and basic mounting—an SCT with a different stroke set will alter the stop positions.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 20 + 30 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 SCT32X20X30 FAQ
It provides four discrete rod positions: fully retracted (0 mm), 20 mm, 30 mm, and the total travel of 50 mm when both sections are pressurized.
Each piston section independently produces 402 N pushing force and 345 N pulling force at 0.5 MPa. The two sections do not combine their thrust for multi-position moves.
