About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X160X160S
The SCT50X160X160S is a double-acting multi-position tandem cylinder that delivers three fixed rod positions: fully retracted (0 mm), mid-stop at 160 mm, and full extension at 320 mm. Each 50 mm bore piston section generates 982 N of push force at 0.5 MPa, scaling to 1767 N at the maximum operating pressure of 0.9 MPa, providing substantial thrust for sorting and diverting tasks.
Equipped with a built-in magnet (-S suffix), this model accepts CMSG, DMSG, or EMSG sensors directly on the tie-rod barrel for reliable end-of-stroke or mid-position sensing. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end ensure smooth deceleration, while the standard PT1/4 ports and 243 mm body length make it a compact solution for multi-stop linear actuation.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X160X160S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X160X160S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 160 / 160 mm |
| Total travel | 320 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 160 mm |
| P2 (both extended) | 320 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 SCT50X160X160S Is Used
3-Position Diverter Gate
Actuates a conveyor diverter to three fixed positions—left, center, and right—using the 0, 160, and 320 mm stops, reliably routing packages without overshoot.
Two-Stage Clamping Fixture
Provides a partial clamp at 160 mm for delicate alignment and a full-power clamp at 320 mm, with the built-in magnet confirming each position to the PLC.
Multi-Level Pallet Stop
Stops pallets at two different heights on a gravity conveyor. The rod extends to 160 mm for a low stop and 320 mm for a high stop, controlled by two solenoid valves.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X160X160S the Right Cylinder?
Choose the SCT50X160X160S when your application requires a compact, three-position actuator without the complexity of two separate cylinders and external stops. If higher force is needed, stepping up to the 63 mm bore provides 1559 N of push per section at 0.5 MPa. For a direct replacement, match the 50 mm bore, both 160 mm strokes, PT port thread, and the -S magnet option; this model uses a basic mount, so verify your existing bracket compatibility.
With a 160 mm stroke per section, the rod is adequately supported for most axial loads, but if significant side forces are present, consider adding an external guide rail to prevent rod bending and ensure long seal life.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 160 + 160 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 SCT50X160X160S FAQ
This model provides three distinct mechanical stop positions: 0 mm (fully retracted), 160 mm (first section extended), and 320 mm (both sections extended, total travel). Because both strokes are equal at 160 mm, the mid-position is exactly halfway.
Yes, it is a direct form-factor replacement for two 50 mm bore cylinders in a tandem setup, provided the strokes are 160 mm each and the total travel is 320 mm. Ensure the replacement matches the PT1/4 port, basic mount, and the -S magnet if you use sensors. It simplifies plumbing and mounting into a single, pre-aligned unit.
