About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X100X350S
This SCT63X100X350S multi-position cylinder provides four distinct rod positions: fully retracted (0 mm), 100 mm, 350 mm, and the total travel of 450 mm. Each piston section delivers a push force of 1559 N at 0.5 MPa, making it a robust choice for tasks requiring two different intermediate stops without complex controls.
The 63 mm bore unit features a 20 mm diameter rod and M16x1.5 rod thread, with PT1/4 ports. Its integrated magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for reliable position feedback. The adjustable air cushion at each end, with a 28 mm cushion length, ensures smooth deceleration across the full 30-800 mm/s speed range.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X100X350S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 100 / 350 mm |
| Total travel | 450 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) | 100 mm |
| P2 (section 2) | 350 mm |
| P3 (both extended) | 450 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 SCT63X100X350S Is Used
Two-Stage Sorting Gate
Operates a diverter gate with three active positions—retracted, partial extend at 100 mm for lane one, and full extend at 450 mm for lane two—using simple pneumatic control.
Multi-Depth Pressing
Provides two controlled pressing depths in a single cycle. The 100 mm stop sets a light pre-press, while the 350 mm extension delivers the final forming stroke at 450 mm total travel.
Staged Part Feeding
Advances components to a 100 mm inspection point, then moves them to a 350 mm pick location. The 450 mm retracted position allows clear loading of the next part.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X100X350S the Right Cylinder?
Selecting an SCT tandem cylinder is ideal when an application needs up to four fixed stopping points from a single compact unit, replacing the complexity of two separate cylinders with external hard stops. For this 100 mm and 350 mm stroke combination, ensure the load at each position is within the 1559 N push capacity per section at 0.5 MPa. If higher force is needed, stepping up to the 80 mm bore provides 2513 N push per section.
When replacing an existing unit, match the 63 mm bore, both the 100 mm and 350 mm strokes, PT port thread, and the basic mounting configuration. The built-in magnet on this -S variant is essential if the original setup uses barrel-mounted sensors. For the 350 mm stroke section, consider external guides if the load has a significant side component to protect the 20 mm rod from bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 350 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 SCT63X100X350S FAQ
This tandem cylinder provides four discrete stop positions: 0 mm (fully retracted), 100 mm, 350 mm, and 450 mm (100 mm + 350 mm). The stops are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, if the two original cylinders were a 100 mm and a 350 mm stroke unit in a 63 mm bore. The SCT63X100X350S integrates both strokes on one common rod line, simplifying mounting and plumbing. Ensure the port thread (PT), basic mount, and magnet option match your existing setup.
