Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X130X130S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X130X130S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 130mm and 130mm give 3 controllable stop positions across a 260mm total travel, with a Ø63mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X130X130S
The SCT63X130X130S is a tandem multi-position pneumatic cylinder that delivers three fixed rod positions: fully retracted (0 mm), intermediate (130 mm), and fully extended (260 mm). Each of its two 63 mm bore sections generates a push force of 1559 N at 0.5 MPa, rising to 2805 N at 0.9 MPa, making it suitable for repetitive two-depth pressing or sorting tasks. The built-in magnet allows CMSG/DMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable pneumatic cushion at each end section is 28 mm long, providing smooth deceleration for the 130 mm strokes. With a body length A(SCT) of 249 mm plus strokes, it fits compactly into machinery where two separate standard cylinders would require more space and complex bracketry.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X130X130S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X130X130S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 130 / 130 mm |
| Total travel | 260 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) | 130 mm |
| P2 (both extended) | 260 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 SCT63X130X130S Is Used
Two-Way Diverter Gate
Actuates a product gate to three distinct positions: closed, divert to lane A (130 mm stroke), and divert to lane B (260 mm total stroke). The discrete stops ensure repeatable alignment without over-travel.
Multi-Depth Pressing
Provides two controlled pressing depths in a single compact unit. The first section extends to 130 mm for a pre-forming operation, and both sections extend to 260 mm for the final press stroke, all with 1559 N of force per section.
Three-Position Stop Pin
Functions as a retractable stop pin with an intermediate position. Fully retracted allows pallets to pass, the 130 mm intermediate stop halts a leading pallet, and the 260 mm full extension stops a trailing pallet for sequenced release.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X130X130S the Right Cylinder?
Select the SCT63X130X130S when your application needs a compact, three-stop actuator without the alignment headaches of two separate cylinders and external hard stops. The 130 mm strokes are standard, ensuring fast availability. If 1559 N of push force per section is insufficient, consider stepping up to the SCT80 bore, which provides 2513 N per section at the same 0.5 MPa pressure. For a lighter load, the SCT50 bore offers 982 N. This cylinder is a direct replacement only for another AirTAC SCT63X130X130S with matching PT ports and the -S magnet option; verify both stroke lengths and the 260 mm total travel before ordering.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 130 + 130 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 SCT63X130X130S FAQ
This model provides 3 distinct mechanical stop positions because both stroke sections are equal at 130 mm. The rod positions are 0 mm (fully retracted), 130 mm (first section extended), and 260 mm (both sections extended for total travel).
Yes, the -S suffix in SCT63X130X130S denotes a built-in magnet. This allows you to mount AirTAC CMSG, DMSG, or EMSG reed or solid-state sensors directly onto the cylinder barrel to detect the piston position at each stop without external brackets.
