About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X108X108S
The SCT32X108X108S is a multi-position tandem cylinder that delivers three distinct rod positions: 0 mm (fully retracted), 108 mm, and 216 mm (total travel). By pressurising the two 108 mm stroke sections independently or together, this 32 mm bore unit provides fixed, repeatable stops without external hard tooling. Each piston section generates 402 N of push force at 0.5 MPa, making it suitable for light sorting and diverting tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing. The 12 mm diameter rod is threaded M10x1.25, and the body length A(SCT) is 233 mm. With PT1/8 ports and an adjustable air cushion of 21 mm, it offers reliable deceleration within a 30-800 mm/s speed range.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X108X108S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X108X108S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 108 / 108 mm |
| Total travel | 216 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 108 mm |
| P2 (both extended) | 216 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 SCT32X108X108S Is Used
3-Way Part Sorting
Directs components to three different conveyor lanes by stopping the rod at 0, 108, or 216 mm, using the fixed mechanical positions for reliable, high-cycle diverting.
Multi-Stop Feeding
Advances material strips or trays in two precise increments of 108 mm, ideal for packaging machines that require a short and a long feed step without servo control.
Two-Depth Pressing
Provides two distinct pressing depths in a light assembly fixture, using the 108 mm and 216 mm stops for inserting components to different levels in a single cycle.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X108X108S the Right Cylinder?
Choose the SCT32X108X108S when a single actuator must provide three fixed stopping points, replacing two separate cylinders and a stop valve. This simplifies the pneumatic circuit and guarantees mechanical synchronization between the positions. If higher force is needed, stepping up to the 40 mm bore SCT provides 628 N of push per section at the same 0.5 MPa pressure. For replacement, match the 32 mm bore, both 108 mm strokes, PT port thread, and the magnetic piston option exactly.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 108 + 108 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 SCT32X108X108S FAQ
This cylinder has 3 distinct mechanical stop positions because both stroke sections are equal at 108 mm. The rod can be reliably positioned at 0 mm (retracted), 108 mm (first section extended), and 216 mm (both sections extended, total travel).
Yes, it is designed to replace two individual cylinders with 108 mm strokes where three synchronized positions are needed. It eliminates the need for external bracketry and sequencing valves, but you must match the 32 mm bore, PT thread, and the magnetic piston (-S) option for a direct functional replacement.
