About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X250X50S
The SCT32X250X50S creates four fixed rod positions—0 mm, 250 mm, 50 mm, and full 300 mm travel—by sequencing pressure to its two tandem piston sections. Each 32 mm bore section delivers 402 N of push force at 0.5 MPa, driven by a 12 mm diameter rod with M10x1.25 threads.
A built-in magnet band allows direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position feedback. The cylinder body has an A-length of 233 mm and uses PT1/8 ports, with a 21 mm air cushion at each end to manage deceleration.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X250X50S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X250X50S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 250 / 50 mm |
| Total travel | 300 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) | 250 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 300 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 SCT32X250X50S Is Used
Two-Stage Sorting Gate
Diverts parts to separate lanes by extending to 250 mm for the primary path and 50 mm for the secondary, with sensor confirmation at each stop.
Dual-Depth Pressing
Applies a light touch at the 50 mm position for pre-forming, then drives to 300 mm total travel for the full-depth press cycle.
Staggered Part Feeding
Advances a pusher bar to 250 mm to load a pallet, retracts to 50 mm for the next row, and fully retracts to 0 mm for clearance.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X250X50S the Right Cylinder?
Choose this 4-position SCT when a single actuator must index to 250 mm and 50 mm stops without the complexity of two separate cylinders. If you need more push force, stepping up to the 40 mm bore provides 628 N per section. For replacement, match the bore, both strokes (250 and 50), PT ports, basic mount, and the -S magnet option exactly.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 250 + 50 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 SCT32X250X50S FAQ
It provides four discrete mechanical stops: 0 mm (fully retracted), 250 mm (first section extended), 50 mm (second section extended), and 300 mm (both sections extended).
Yes, the -S suffix indicates a factory-installed magnetic piston, making it compatible with AirTAC CMSG, DMSG, or EMSG sensors that clamp directly onto the tie-rod barrel.
