About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X220S
The SCT32X50X220S is a double-acting multi-position cylinder providing four fixed rod positions: 0 mm, 50 mm, 220 mm, and 270 mm total travel. Each 32 mm bore section delivers 402 N of push force at 0.5 MPa, driven by a 12 mm diameter rod. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for position feedback.
With a compact body length A of 233 mm and a 21 mm adjustable air cushion on each section, this tandem cylinder decelerates loads smoothly at both ends of every stroke. The PT1/8 ports and M10x1.25 rod thread make it a direct fit for standard pneumatic circuits needing sequenced, multi-stop actuation without complex external stops.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X220S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X220S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 220 mm |
| Total travel | 270 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) | 50 mm |
| P2 (section 2) | 220 mm |
| P3 (both extended) | 270 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 SCT32X50X220S Is Used
Two-Stage Sorting Gate
Diverts packages to three separate lanes by stopping at 50 mm, 220 mm, or full extension, using the magnet sensors to confirm each position before the next cycle.
Multi-Depth Insertion
Installs components at two different depths in a single fixture. The rod advances to 50 mm for a partial press, then to 220 mm for a full-depth seat, with the 270 mm position used for part ejection.
Sequential Part Feeding
Meters parts from a magazine with a three-step sequence: a 50 mm advance to separate, a 220 mm move to transfer, and full retraction to 0 mm to accept the next component.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X220S the Right Cylinder?
Choose the SCT32X50X220S when your process requires four distinct, repeatable stop points from a single tie-rod assembly, eliminating the need to align two separate cylinders. If the 402 N push force per section is marginal, stepping up to a 40 mm bore provides 628 N at the same pressure. For replacement, match the 32 mm bore, both the 50 mm and 220 mm strokes, PT port thread, and the -S magnet option. Given the 220 mm stroke on the second section, ensure the rod is guided if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 220 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 SCT32X50X220S FAQ
This tandem cylinder provides four discrete mechanical stops: fully retracted at 0 mm, the first section extended at 50 mm, the second section extended at 220 mm, and both sections extended for a total travel of 270 mm. It is not a servo cylinder and cannot stop at arbitrary intermediate points.
Yes, it is designed to replace two individually mounted 32 mm bore cylinders with 50 mm and 220 mm strokes. The replacement must match the PT port thread and the -S magnet option to ensure sensor compatibility. The tie-rod construction means mounting is via the basic body or optional SCT foot/flange kits, not ISO 15552 profiles.
