Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X90X10S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X90X10S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 90mm and 10mm give 4 controllable stop positions across a 100mm total travel, with a Ø40mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X90X10S
The SCT40X90X10S tandem cylinder delivers four fixed rod positions—0 mm, 10 mm, 90 mm, and 100 mm total travel—by combining two piston sections on a single axis. With a 40 mm bore and 16 mm rod, each actuated section provides 628 N of push force at 0.5 MPa, making it suitable for light sorting or diverting tasks where a short intermediate stop and a longer primary stroke are needed.
This model includes a built-in magnet (-S suffix), allowing CMSG or DMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing at any of the four stops. The body length A(SCT) is 235 mm, and the adjustable air cushion at each end decelerates the 16 mm rod smoothly, protecting the assembly during high-cycle operation.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X90X10S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X90X10S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 90 / 10 mm |
| Total travel | 100 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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) | 90 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 100 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SCT40X90X10S Is Used
Two-Way Part Diverting
Use the 10 mm stroke to nudge parts onto a bypass lane and the 90 mm stroke to push them fully onto the main conveyor, all from a single compact cylinder.
Dual-Depth Insertion
The 10 mm stop acts as a precise pre-insertion position for delicate components, followed by the full 90 mm stroke to press them home, preventing impact damage.
Staged Clamping Fixture
Achieve a light 10 mm touch-clamp for alignment and a full 90 mm power-clamp stroke, with sensors confirming each position via the built-in magnet ring.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X90X10S the Right Cylinder?
Choose the SCT40X90X10S when your process requires two distinct forward positions without the complexity of two separate cylinders and a mounting bracket. The 90 mm and 10 mm strokes create an asymmetric 4-position set, ideal for a two-depth insertion or a diverting gate that needs a partial retract. If you need more force, stepping up to a 50 mm bore provides 982 N of push per section at the same pressure.
For replacement, match the 40 mm bore, the exact 90 mm and 10 mm strokes, PT port thread, and the -S magnet option. This is a basic mount model, so confirm your existing mounting feet or flange are compatible. With the 90 mm stroke exceeding 80 mm, ensure the rod is guided if the load applies any significant side force to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 90 + 10 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 SCT40X90X10S FAQ
It provides 4 discrete stop positions: 0 mm (fully retracted), 10 mm, 90 mm, and 100 mm (fully extended). The positions are achieved by pressurizing the 10 mm section, the 90 mm section, or both together.
Yes, the -S suffix indicates a built-in magnet, so you can mount AirTAC CMSG, DMSG, or EMSG sensors directly on the cylinder barrel to sense the piston position at any of the four stops.
