About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X110S
The SCT32X150X110S tandem cylinder provides four fixed rod positions—0 mm, 110 mm, 150 mm, and the total travel of 260 mm—by independently pressurizing its two piston sections. This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for reliable end-of-stroke or mid-stroke position sensing without extra brackets.
Each 32 mm bore section delivers 402 N of push force at 0.5 MPa, with a 12 mm diameter piston rod and M10x1.25 rod-end threads. The cylinder body has a 21 mm adjustable air cushion at each end and an overall A(SCT) length of 233 mm, making it a compact solution for light-duty sorting or diverting tasks where a single actuator must reach multiple hard stops.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X110S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X110S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 150 / 110 mm |
| Total travel | 260 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) | 110 mm |
| P3 (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 (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 SCT32X150X110S Is Used
Two-Way Part Diverting
Uses the 110 mm and 150 mm stops to guide parts into two separate lanes from a single conveyor, with the 260 mm full-extension position clearing the gate for a third flow path.
Multi-Stop Pick-and-Place
Provides four distinct vertical or horizontal positions for a gripper, enabling a single compact actuator to pick from one height and place at two different levels before fully retracting.
Staged Clamping or Pressing
Applies an initial clamp at 110 mm, a secondary press at 150 mm, and a full-ejection stroke at 260 mm, all controlled by sequencing air pressure to the two cylinder sections.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X150X110S the Right Cylinder?
Choose the SCT when a process needs two or more fixed mechanical stops from one actuator, eliminating the complexity of dual cylinders with external hard stops. For this 32 mm bore model, verify that the 402 N push force per section at 0.5 MPa is sufficient; if higher thrust is needed, stepping up to a 40 mm bore SCT provides 628 N per section. As a direct replacement, match the bore, both strokes (150 mm and 110 mm), the PT port thread, and the -S magnet option. Note that with a 150 mm section stroke, ensure the guided load is aligned to prevent side-loading and rod bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 150 + 110 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 SCT32X150X110S FAQ
It provides 4 discrete mechanical stops: fully retracted (0 mm), the first section extended (110 mm), the second section extended (150 mm), and both sections extended for the total travel (260 mm). The stops are fixed by the two stroke lengths and are not infinitely adjustable.
No. Like all standard pneumatic cylinders, the SCT32X150X110S will drift or drop if pressure is exhausted from a section. If a load must be held at the 110 mm or 150 mm position without live pressure, you must add an external rod brake or a pilot-operated check valve.
