About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X115S
The SCT32X50X115S is a double-acting multi-position tandem cylinder that provides four distinct rod positions from two strokes on a single piston rod. By pressurising the 50 mm section, the 115 mm section, or both, the rod can be accurately placed at 0 mm, 50 mm, 115 mm, and the full combined travel of 165 mm.
Each actuated piston section delivers 402 N of push force at 0.5 MPa, rising to 724 N at the 0.9 MPa maximum operating pressure. The 12 mm diameter rod and M10x1.25 rod thread suit light-duty sorting and diverting tasks. A built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for position confirmation, and the 21 mm adjustable air cushion at each end ensures smooth deceleration across the 233 mm body length.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X115S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X115S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 115 mm |
| Total travel | 165 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) | 115 mm |
| P3 (both extended) | 165 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 SCT32X50X115S Is Used
Multi-Stop Diverter Gate
Controls a diverter plate to four fixed positions for routing small packages or components down separate conveyor lanes, with sensor feedback from the integrated magnet.
Two-Depth Pressing Station
Provides two distinct pressing depths (50 mm and 115 mm) plus a full-extension position (165 mm) for assembling components with staged insertion requirements.
Staged Part Ejection
Ejects parts from a magazine at three different stroke lengths to place components into separate bins or fixtures based on a quality inspection signal.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X115S the Right Cylinder?
This 4-position cylinder replaces complex setups that would otherwise require two separate cylinders with external stops, reducing mounting points and alignment effort. For applications needing higher force per section, consider stepping up to the 40 mm bore SCT40, which provides 628 N of push at 0.5 MPa. To ensure a correct replacement, match the 32 mm bore, both the 50 mm and 115 mm section strokes, the PT port thread, and the built-in magnet (-S suffix).
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 115 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 SCT32X50X115S FAQ
This cylinder has 4 discrete mechanical stops: fully retracted (0 mm), the first section extended (50 mm), the second section extended (115 mm), and both sections extended for the total travel (165 mm).
Yes, it is designed to replace two separate cylinders and external hard stops with a single, compact tandem unit. Ensure the replacement matches the 32 mm bore, both the 50 mm and 115 mm strokes, the PT port thread, and the -S magnet option for sensor compatibility.
