About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X350X150S
This SCT32X350X150S multi-position cylinder delivers four fixed rod positions: fully retracted (0 mm), 150 mm, 350 mm, and the total travel of 500 mm. Each of the two 32 mm bore sections generates 402 N of push force at 0.5 MPa, providing a compact tandem solution for sequencing tasks without complex external stops. The built-in magnet (suffix -S) allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke or mid-position detection.
Engineered as a durable tie-rod cylinder, the unit features a 12 mm diameter piston rod and M10x1.25 rod thread. Both sections include an adjustable pneumatic cushion (21 mm length) to decelerate the load smoothly, and the PT1/8 ports keep the footprint compact. The standard TPU seals suit ambient temperatures from -20 to +70 °C, making this a robust choice for general industrial multi-stop applications.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X350X150S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 350 / 150 mm |
| Total travel | 500 mm |
| Stop positions | 4 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 (4)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 350 mm |
| P2 (section 2) | 150 mm |
| P3 (both extended) | 500 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 SCT32X350X150S Is Used
Two-Lane Part Diverting
Use the 150 mm and 350 mm intermediate stops to push products off a main conveyor into two different chutes or lanes, controlled by a single cylinder.
Sequential Clamping
Apply a low clamping force at the 150 mm position for delicate alignment, then advance to the full 500 mm stroke for high-pressure holding, all with one actuator.
Two-Depth Pressing
Achieve a pre-press depth at 350 mm and a final form depth at 500 mm total travel, eliminating the need for a secondary press station or complex tooling.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X350X150S the Right Cylinder?
Choose the SCT series when your application needs two or three intermediate hard stops that are more precise and repeatable than an external mechanical stop on a single cylinder. The SCT32X350X150S offers a 150 mm and a 350 mm intermediate position, ideal for diverting parts to two separate lanes. If you need higher force per section, step up to the 40 mm bore SCT40, which provides 628 N of push at the same 0.5 MPa pressure. For a direct replacement, match the 32 mm bore, the exact 350 mm first stroke and 150 mm second stroke, PT port thread, and the -S magnet option. With a 350 mm stroke on the first section, ensure the rod is adequately guided if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 350 + 150 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 SCT32X350X150S FAQ
This tandem cylinder provides 4 discrete mechanical stops. The rod positions are 0 mm (fully retracted), 150 mm (section 2 extended), 350 mm (section 1 extended), and 500 mm (both sections extended, total travel).
To ensure a drop-in fit, match the 32 mm bore, the first stroke of 350 mm, the second stroke of 150 mm, and the PT port thread. The replacement must also include the -S suffix for the built-in magnet so your existing CMSG or DMSG sensors will clamp directly onto the tie-rod barrel.
