Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X10
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X10 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 50mm and 10mm give 4 controllable stop positions across a 60mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X10
The SCT32X50X10 is a tie-rod multi-position cylinder that delivers four discrete rod stops from two pneumatic sections on a common piston rod. With section strokes of 50 mm and 10 mm, the reachable positions are 0 mm (fully retracted), 10 mm, 50 mm, and the total travel of 60 mm. This 32 mm bore actuator uses a 12 mm diameter rod and provides a per-section push force of 402 N at 0.5 MPa, making it suitable for compact sorting or diverting tasks where two different short extensions are needed.
The cylinder body has an A(SCT) length of 233 mm and features an adjustable air cushion of 21 mm on each section for smooth end-of-stroke deceleration. Ports are PT1/8 with an M10x1.25 rod thread. Standard TPU seals give an operating temperature range of -20 to +70 °C, and the double-acting design requires continuous pressure to hold a position—if a load must stay put without air, an external rod lock or pilot-operated check valve is essential.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X10 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 10 mm |
| Total travel | 60 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) | 10 mm |
| P3 (both extended) | 60 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 SCT32X50X10 Is Used
Two-Way Part Diverting
Uses the 10 mm and 50 mm stops to guide small components into two separate chutes from a single feed lane, eliminating a second actuator and simplifying the control scheme.
Dual-Depth Insertion
Provides a 10 mm pre-insertion stage and a 50 mm full-seating stroke for pressing delicate pins or connectors, preventing impact damage with a controlled two-step motion.
Multi-Stop Label Applicator
Positions a tamp pad at 10 mm for small labels and 50 mm for larger formats on the same packaging line, reducing changeover time between product runs.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X10 the Right Cylinder?
Choose the SCT32X50X10 when a single actuator must provide two distinct, repeatable mid-stroke stopping points instead of using two separate cylinders and external hard stops. The 50 mm and 10 mm strokes create four fixed positions, which is ideal for a two-step feed or a diverter gate that needs a short and a medium throw. If the 402 N push force per section at 0.5 MPa is too light, stepping up to the SCT40 bore delivers 628 N per section at the same pressure.
For direct replacement, match the 32 mm bore, both the 50 mm and 10 mm section strokes, PT port thread, and basic mounting. If your application uses sensors, order the -S magnet variant so CMSG/DMSG/EMSG switches can clamp directly to the tie-rod barrel.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 10 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 SCT32X50X10 FAQ
It provides four discrete mechanical stops: 0 mm (fully retracted), 10 mm (section 2 extended), 50 mm (section 1 extended), and 60 mm (both sections extended, which is the total travel). The positions are fixed by the two section strokes and are not infinitely adjustable.
Yes, if your sequence needs a 10 mm and a 50 mm stroke from the same rod axis. It replaces two individual cylinders and their mounting hardware with one tandem unit. Ensure the replacement matches the 32 mm bore, both stroke lengths, PT1/8 ports, and basic mounting style.
