About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X600X50S
The AirTAC SCT50X600X50S is a tandem multi-position cylinder delivering four discrete rod stops: 0 mm (fully retracted), 50 mm, 600 mm, and the full 650 mm extension. This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for position feedback. Each piston section provides 982 N of push force at 0.5 MPa, with a 20 mm diameter rod and M16x1.5 rod thread.
With a 600 mm primary stroke, this cylinder is a made-to-order, non-standard configuration suited for long-reach multi-stop tasks. The body length A is 243 mm, and it features an adjustable pneumatic cushion of 21 mm on each end to manage end-of-stroke impact. As a genuine AirTAC component, it ensures reliable tandem operation for sorting or diverting applications requiring extended travel.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X600X50S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X600X50S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 600 / 50 mm |
| Total travel | 650 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). This configuration exceeds the 500 mm standard section stroke, so it is a non-standard / made-to-order build. 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) | 600 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 650 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 SCT50X600X50S Is Used
Long-Reach Diverter Gates
Actuates a diverter gate across four positions on a wide conveyor, sorting packages to separate lanes with the 650 mm total travel.
Multi-Stop Material Pusher
Pushes products to two distinct depths at 50 mm and 600 mm on a packaging line, with a fully retracted home and a 650 mm clear-out position.
Two-Stage Clamping Fixture
Provides a 50 mm pre-clamp and a 600 mm final clamp stroke for large workpieces, using the magnet to confirm each discrete stop.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X600X50S the Right Cylinder?
Choose the SCT50X600X50S when a single actuator must provide four fixed positions along a 650 mm total stroke, eliminating the complexity of two separate cylinders and external stops. For higher force requirements, consider stepping up to the 63 mm bore, which delivers 1559 N of push per section at the same 0.5 MPa pressure. A direct replacement must match the 50 mm bore, both 600 mm and 50 mm strokes, PT port threads, and the integrated magnet. Due to the extended 600 mm stroke, ensure the load is guided or supported to prevent rod buckling and side-load wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 600 + 50 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 SCT50X600X50S FAQ
This cylinder provides four distinct rod positions: 0 mm, 50 mm, 600 mm, and the total extended length of 650 mm. The stops are achieved by pressurizing the two piston sections independently or together.
Yes, the SCT50X600X50S replaces a two-cylinder setup for a 4-position sequence. Ensure the replacement matches the 50 mm bore, 600 mm and 50 mm strokes, PT ports, and the -S magnet option for sensor compatibility.
