About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X160X90
The SCT63X160X90 is a double-acting tandem cylinder that provides four fixed rod positions—0 mm, 90 mm, 160 mm, and the full 250 mm extension—by pressurising its two piston sections independently or together. Each section delivers 1559 N of push force at 0.5 MPa (2805 N at 0.9 MPa), driven by a 20 mm rod through PT1/4 ports, making it a robust choice for multi-stop material handling tasks.
With a 28 mm air cushion at each end and a body length A of 249 mm, this tie-rod cylinder decelerates loads smoothly without external shock absorbers. The 63 mm bore sits in the middle of the SCT range, offering a balanced force-to-size ratio for sorting gates, two-depth pressing, or diverting conveyors where four distinct positions eliminate the need for two separate actuators.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X160X90 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X160X90 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 160 / 90 mm |
| Total travel | 250 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) | 160 mm |
| P2 (section 2) | 90 mm |
| P3 (both extended) | 250 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 SCT63X160X90 Is Used
Four-Way Diverter Gate
Actuates a chute or gate to four distinct positions—fully closed, partial bypass at 90 mm, main flow at 160 mm, and full open at 250 mm—directing product to separate lanes on a packaging line.
Two-Depth Pressing Station
Provides a first pressing depth at 90 mm for pre-forming and a second at 160 mm for final compression, with the full 250 mm stroke used for part ejection, all from one compact cylinder.
Multi-Stop Pusher
Pushes trays or boxes to three different conveyor lanes: a near lane at 90 mm, a middle lane at 160 mm, and a far lane at 250 mm, replacing a more complex two-cylinder pusher setup.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X160X90 the Right Cylinder?
Choose the SCT63X160X90 when your process needs four defined mechanical stops without the complexity of servo controls or multiple single-stroke cylinders. If your load requires slightly less force, stepping down to a 50 mm bore provides 982 N push per section at 0.5 MPa; for heavier work, the 80 mm bore delivers 2513 N. This model is a direct replacement for an existing AirTAC SCT63X160X90 with PT ports and basic mounting—always match both stroke values, port thread, and mounting style to ensure identical positioning logic.
Because the first stroke extends to 160 mm, consider external guiding or a rod-alignment coupler if the load applies significant side force or the cylinder is mounted horizontally with a long tooling offset. The tie-rod construction allows you to add FA or FB flanges, LB feet, or CA/CB rear clevises later if your mounting requirements change.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 160 + 90 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 SCT63X160X90 FAQ
It provides four discrete mechanical stop positions: 0 mm (fully retracted), 90 mm (section 2 extended), 160 mm (section 1 extended), and 250 mm (both sections extended). The positions are fixed by the two stroke lengths and are selected by pressurising the corresponding cylinder sections.
Yes, if your application currently uses two SC63 cylinders with strokes of 160 mm and 90 mm to achieve three or four positions, the SCT63X160X90 can replace them with a single tandem unit. Ensure the port thread (PT), mounting style, and both stroke lengths match exactly, and verify that the per-section force of 1559 N at 0.5 MPa meets your load requirements.
