About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X100S
The SCT63X150X100S is a double-acting multi-position tandem cylinder that delivers four fixed rod positions—0 mm, 100 mm, 150 mm, and the full 250 mm total travel—by pressurising its two piston sections independently or together. Each section generates 1559 N of push force at 0.5 MPa (2805 N at 0.9 MPa), driven through a 20 mm diameter rod with PT1/4 ports and a 28 mm adjustable air cushion for end-of-stroke deceleration.
A built-in magnet is integrated into the piston, allowing CMSG, DMSG, or EMSG solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing at any of the four stops. The body length A is 249 mm, and the cylinder operates on standard 40 µm filtered air from 0.15 to 1.0 MPa, with TPU seals rated for -20 to +70 °C.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X100S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 150 / 100 mm |
| Total travel | 250 mm |
| Stop positions | 4 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 (4)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 150 mm |
| P2 (section 2) | 100 mm |
| P3 (both extended) | 250 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 SCT63X150X100S Is Used
Two-Depth Sorting Gate
Diverts parts to separate conveyors at 100 mm and 150 mm extension, with full retraction clearing the line—ideal for packaging lines with multiple reject stations.
Staged Clamping Fixture
Applies a 100 mm low-force pre-clamp stroke to align a part, then drives to 150 mm for full-pressure holding, preventing part distortion in assembly cells.
Multi-Level Part Transfer
Picks a component at 0 mm, presents it for inspection at 100 mm, and transfers it to an upper unloading nest at 250 mm total travel on a single rod line.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X150X100S the Right Cylinder?
Choose this 4-position SCT when a single actuator must serve two different extension depths and a full-retract home, eliminating the complexity and air consumption of two separate cylinders with external hard stops. If your load requires more force per section, step up to the 80 mm bore SCT, which provides 2513 N of push at 0.5 MPa; for a lighter, more compact alternative, the 50 mm bore delivers 982 N.
To replace an existing SCT63X150X100S, match the 63 mm bore, both the 150 mm and 100 mm section strokes, the PT port thread, the basic mounting configuration, and the -S magnet option. For strokes of 150 mm and above, ensure the external guide system is aligned to prevent side-loading and rod deflection during multi-stop operation.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 150 + 100 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 SCT63X150X100S FAQ
It provides four discrete mechanical stops: 0 mm (fully retracted), 100 mm (section two extended), 150 mm (section one extended), and 250 mm (both sections extended). The stops are fixed by the two stroke lengths and cannot be varied infinitely.
Yes, it replaces a pair of single-rod cylinders of 150 mm and 100 mm stroke on the same rod axis, provided the mounting, PT1/4 ports, and the -S magnet sensor compatibility are matched. It uses one rod line to achieve the four positions.
