About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X52X95S
The SCT32X52X95S is a 32 mm bore multi-position air cylinder that creates four defined rod-end locations without external hard stops. By pressurising its two piston sections independently or together, the rod reaches 0 mm (fully retracted), 52 mm, 95 mm, and the combined travel of 147 mm. Each actuated section delivers 402 N of push force at 0.5 MPa, driven through a 12 mm diameter rod with M10x1.25 threads.
A built-in magnet band on the piston allows CMSG, DMSG, or EMSG solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing at every stop. The cylinder body has a base length of 233 mm and uses 21 mm of adjustable air cushion at each end section to manage deceleration. PT1/8 ports and the standard TPU seals suit filtered-air operation from -20 to +70 °C.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X52X95S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 52 / 95 mm |
| Total travel | 147 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) | 52 mm |
| P2 (section 2) | 95 mm |
| P3 (both extended) | 147 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 SCT32X52X95S Is Used
Two-Station Diverter Gate
A product gate on a conveyor uses the 52 mm stroke to divert to lane A and the 95 mm stroke to divert to lane B. Full 147 mm extension sends rejects down a third path while the retracted position allows straight-through flow.
Multi-Level Pallet Stop
The cylinder positions a stop blade at two different heights above a roller bed. The 52 mm stop arrests light totes, the 95 mm stop holds heavier pallets, and full retraction clears the lane completely.
Two-Depth Press Feed
In a small assembly press, the SCT32X52X95S advances a forming tool to a 52 mm pre-compression position, then to a 95 mm final-set depth. The 147 mm total stroke retracts the tool fully for part loading.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X52X95S the Right Cylinder?
This tandem unit replaces setups that would otherwise need two separate 32 mm bore cylinders and external bracketry to achieve three intermediate positions. The four-stop sequence is ideal when a transfer arm must serve two distinct advance points and a full-extension point from a single retracted home. If the 402 N push per section is marginal for the load, stepping up to the 40 mm bore SCT40 series raises the per-section push to 628 N at the same 0.5 MPa pressure. For direct replacement, match the 32 mm bore, both the 52 mm and 95 mm strokes, the PT port thread, the basic mounting style, and the -S magnet option to retain sensor compatibility.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 52 + 95 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 SCT32X52X95S FAQ
The rod stops at four discrete positions: 0 mm (fully retracted), 52 mm (section one extended), 95 mm (section two extended), and 147 mm (both sections extended, which is the sum of the two strokes).
No. Like any standard double-acting pneumatic cylinder, the SCT32X52X95S will drift or drop if supply pressure is removed or the directional valve centers. If the load must be mechanically locked at an intermediate stop, an external rod brake or pilot-operated check valve is required.
