About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X200
The SCT32X150X200 is a tandem multi-position cylinder that delivers four fixed rod positions—0, 150, 200, and 350 mm—by pressurising its two piston sections independently or together. With a 12 mm diameter rod and PT1/8 ports, each section generates 402 N of push force at 0.5 MPa, scaling to 724 N at the maximum 0.9 MPa operating pressure.
This 32 mm bore tie-rod cylinder uses an adjustable air cushion (21 mm length) at each end to manage deceleration. The body length A(SCT) is 233 mm, making it a space-efficient alternative to two separate actuators for multi-stop tasks. It operates on filtered air from 0.15 to 1.0 MPa across a -20 to +70 °C range with its standard TPU seals.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X200 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 150 / 200 mm |
| Total travel | 350 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) | 150 mm |
| P2 (section 2) | 200 mm |
| P3 (both extended) | 350 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 SCT32X150X200 Is Used
Two-Stage Part Diverting
Use the four discrete positions to route parts to three different conveyor lanes. Retract for lane one, extend to 150 mm for lane two, 200 mm for lane three, or fully extend to 350 mm to bypass all lanes.
Multi-Depth Pressing
Achieve two distinct pressing depths in one cycle. The 150 mm stroke provides a shallow pre-press, while the 200 mm stroke delivers a deeper final form, with the 350 mm total travel used for part ejection.
Sequential Clamping
Clamp a workpiece with a light force at the 150 mm position, then apply full clamping pressure at the 200 mm position. The intermediate stop prevents damage to delicate components before the final lock.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X200 the Right Cylinder?
Select the SCT32X150X200 when your application needs four precise, repeatable stop positions without the complexity of servo controls or multiple cylinders. It is a direct fit replacement for another AirTAC SCT of the same 32 mm bore, 150 mm and 200 mm strokes, PT thread, and basic mounting configuration. If your load requires more force per section, consider stepping up to the 40 mm bore, which provides 628 N of push at 0.5 MPa. For section strokes over 300 mm, evaluate side-loading and consider adding an external guide to protect the 12 mm rod from bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 150 + 200 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 SCT32X150X200 FAQ
It provides four distinct mechanical stop positions: 0 mm (fully retracted), 150 mm (section one extended), 200 mm (section two extended), and 350 mm (both sections extended for total travel).
Yes, if your sequence requires fixed stops at 150 mm and 200 mm. The SCT32X150X200 consolidates two strokes into one tie-rod body, reducing mounting hardware and eliminating the need to synchronise two separate actuators. Ensure the replacement matches your port thread (PT) and mounting style.
