About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X30
The AirTAC SCT50X60X30 is a tie-rod multi-position cylinder that provides four fixed rod positions from a single compact assembly: 0 mm (fully retracted), 30 mm, 60 mm, and 90 mm (full extension). By pressurising the 30 mm or 60 mm stroke sections independently or together, you achieve repeatable, discrete stopping points without external hard stops or complex servo controls. Each 50 mm bore section delivers 982 N of push force at 0.5 MPa, making it a robust solution for sequenced material handling tasks.
This double-acting tandem cylinder uses a 20 mm diameter piston rod with M16x1.5 threads and PT1/4 ports, and features an adjustable air cushion at both ends for smooth deceleration. The body length A(SCT) is 243 mm, providing a compact footprint for its 90 mm total travel. Operating on filtered air from 0.15 to 1.0 MPa, it suits standard industrial temperatures of -20 to +70 °C with its default TPU seals.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X30 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 60 / 30 mm |
| Total travel | 90 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, 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) | 60 mm |
| P2 (section 2) | 30 mm |
| P3 (both extended) | 90 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 SCT50X60X30 Is Used
Two-Way Part Diverting
Use the 30 mm and 60 mm stop positions to guide products onto two separate conveyor lanes, eliminating the need for a separate actuator at each divert point.
Dual-Depth Insertion
Program a press or insertion tool to stop at 30 mm for a shallow set and 60 mm for a deeper set, ensuring consistent placement for components with two different seating requirements.
Sequential Clamping
Apply a light clamp force at the 30 mm position before driving to the full 90 mm extension for a secondary high-force operation, all from a single pneumatic circuit.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X30 the Right Cylinder?
Choose the SCT50X60X30 when your application needs four distinct mechanical stop positions without the complexity and cost of two separate cylinders and their mounting hardware. This model is ideal for diverting parts to two different lanes or setting two different insertion depths. If your force requirement is lower, consider stepping down to the 40 mm bore SCT, which provides 628 N of push per section at 0.5 MPa. For a direct replacement, ensure the new unit matches the 50 mm bore, 60 mm and 30 mm strokes, PT port thread, and basic mounting configuration.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 60 + 30 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 SCT50X60X30 FAQ
This cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 30 mm (first section extended), 60 mm (second section extended), and 90 mm (both sections extended for total travel).
No, like any standard pneumatic cylinder, it requires continuous air pressure to maintain a position. If a load must be held at the 30 mm or 60 mm stop without pressure, you must add an external mechanical rod lock or a pilot-operated check valve to the circuit.
