Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300S 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 Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300S
The SCT32X300X300S is a double-acting multi-position tandem cylinder that delivers three precise, repeatable stop positions along its 600 mm total stroke: fully retracted (0 mm), mid-stroke (300 mm), and fully extended (600 mm). Each 32 mm bore section generates 402 N of push force at 0.5 MPa, driven through a 12 mm diameter piston rod, making it a compact yet robust actuator for light-duty sorting or diverting tasks.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position feedback. The cylinder body has a base length of 233 mm, uses PT1/8 ports, and features an adjustable air cushion of 21 mm on each section to decelerate the load smoothly at both ends of the travel.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 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 | PT1/8 |
| 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 (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 (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 SCT32X300X300S Is Used
3-Position Diverter Gate
Uses the retracted, mid-stroke, and extended positions to route packages or parts to three separate conveyor lanes from a single infeed point.
Multi-Stop Part Feeding
Advances components to two distinct assembly stations with a single cylinder, stopping precisely at 300 mm and 600 mm for sequential operations.
Two-Depth Pressing or Staking
Provides a controlled partial-extension stop at 300 mm for a light pre-press, followed by full 600 mm extension for the final forming or staking force.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X300S the Right Cylinder?
Choose the SCT32X300X300S when your application needs three fixed mechanical stops without the complexity of servo control or external hard stops on a standard cylinder. For applications requiring higher force, stepping up to the SCT40 bore provides 628 N of push per section at the same 0.5 MPa pressure. When replacing an existing unit, match the 32 mm bore, both 300 mm section strokes, PT port thread, and the -S magnet option to ensure sensor compatibility. With a 300 mm stroke per section, ensure the rod is adequately guided if significant side loads are present to prevent bending or premature seal wear.
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 SCT32X300X300S FAQ
Because both stroke sections are equal at 300 mm, this model provides three distinct mechanical stops: 0 mm (fully retracted), 300 mm (first section extended), and 600 mm (both sections extended for total travel).
Yes, in many cases a single SCT32X300X300S can replace two independently mounted SC32X300 cylinders to achieve three-position functionality, saving space and simplifying plumbing. Ensure the replacement matches the 32 mm bore, both 300 mm strokes, PT ports, and the -S magnet option if sensors are used.
