Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X300X300S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X300X300S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 300mm and 300mm give 3 controllable stop positions across a 600mm total travel, with a Ø63mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X300X300S
The SCT63X300X300S is a tie-rod multi-position cylinder that delivers three fixed rod positions: fully retracted (0 mm), mid-stop (300 mm), and full extension (600 mm). Each of its two 63 mm bore sections generates 1559 N of push force at 0.5 MPa, making it a robust actuator for sorting gates or two-depth pressing stations where a single cylinder body replaces dual actuators.
This model includes a factory-installed magnet (suffix -S), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position confirmation. The 20 mm diameter rod and 28 mm air cushion at each end provide smooth deceleration, while the PT1/4 ports and M16x1.5 rod thread ensure straightforward pneumatic connections. The body length A(SCT) is 249 mm plus twice the stroke, giving a compact tandem footprint.

|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 300 / 300 mm |
| Total travel | 600 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 300 mm |
| P2 (both extended) | 600 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 SCT63X300X300S Is Used
3-Position Diverter Gate
Stops at 0, 300, and 600 mm route packages to three separate conveyor lanes. The built-in magnet with DMSG sensors confirms each gate position before the next cycle.
Two-Depth Pressing
A partial stroke to 300 mm applies a light pre-clamp, while the full 600 mm stroke delivers the final press force. The 1559 N per section at 0.5 MPa handles moderate forming tasks.
Multi-Stop Material Feed
Feeds strip material in two precise increments (300 mm and 600 mm) for a stamping die. The 20 mm rod and tie-rod construction maintain alignment under repetitive cycling.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X300X300S the Right Cylinder?
Choose the SCT63X300X300S when your application needs three positive mechanical stops without the complexity of two separate cylinders and a manifold. It is a direct form-fit replacement only for another AirTAC SCT with 63 mm bore, both strokes set to 300 mm, PT ports, basic mounting, and the -S magnet. If the 1559 N per-section push at 0.5 MPa is more than needed, stepping down to the 50 mm bore SCT50X300X300 reduces per-section push to 982 N at the same pressure. For longer 300 mm strokes, ensure the guided load is aligned with the rod axis to prevent side-load bending, and consider an external guide or rod support if the tooling is heavy.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 300 + 300 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 SCT63X300X300S FAQ
It provides 3 distinct mechanical stop positions: 0 mm (fully retracted), 300 mm (first section extended), and 600 mm (both sections extended, total travel). Because both stroke sections are equal, the 300 mm and 600 mm stops are the only extended positions.
Yes, in applications where you need two fixed extension points from a single rod line. The SCT63X300X300S combines two piston sections in one tie-rod body, saving mounting space and eliminating the need to synchronize two separate actuators. It is a direct replacement only for an identical AirTAC SCT63X300X300S with PT ports, basic mount, and the -S magnet.
