About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X100X50S
The AirTAC SCT63X100X50S is a double-acting multi-position tie-rod cylinder that delivers four fixed rod positions from its tandem piston layout: 0 mm (fully retracted), 50 mm, 100 mm, and 150 mm (total travel). Each 63 mm bore section provides 1559 N of push force at 0.5 MPa, rising to 2805 N at the maximum operating pressure of 0.9 MPa, making it a robust choice for sequenced material handling where two distinct intermediate stops are required.
This model includes a built-in magnet (suffix -S), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for reliable end-of-stroke and intermediate position detection. The cylinder features a 20 mm diameter piston rod, M16x1.5 rod thread, PT1/4 ports, and a 28 mm adjustable air cushion in each section to decelerate the load smoothly. The body length A(SCT) is 249 mm, and the standard operating temperature range is -20 to +70 °C with TPU seals.

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) | 100 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 150 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 SCT63X100X50S Is Used
Four-Position Diverter Gate
Actuate a conveyor diverter to four precise locations: home (0 mm), low divert (50 mm), mid divert (100 mm), and full bypass (150 mm). The SCT63X100X50S eliminates the need for two separate cylinders and complex sequencing valves.
Two-Depth Pressing Station
Control a pressing tool to two distinct depths in one cycle. The first piston section extends 50 mm for a pre-form operation, and the second adds 100 mm for the final press depth, with sensor confirmation at each stage via the built-in magnet.
Multi-Stop Pallet Indexing
Index a pallet on a roller conveyor to four fixed positions for loading, inspection, welding, and unloading. The SCT63X100X50S provides the 0, 50, 100, and 150 mm stops with 1559 N of force per section, holding position against process forces when pressurized.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X100X50S the Right Cylinder?
Select the SCT63X100X50S when your application needs four discrete stopping points without the complexity of servo controls or multiple separate cylinders. The 100 mm and 50 mm strokes create positions ideal for a two-step feed-and-place or a diverting gate with an intermediate pause. If your load requires higher force, consider stepping up to the 80 mm bore (SCT80X100X50S), which offers 2513 N of push per section at 0.5 MPa; for a lighter, more compact solution, the 50 mm bore provides 982 N. To replace an existing unit, match the 63 mm bore, both strokes (100 mm and 50 mm), PT port thread, and the -S magnet option exactly. For strokes of 100 mm and above, ensure the rod is adequately guided if significant side loads are present to prevent bending and premature seal wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 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 SCT63X100X50S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 50 mm (stroke 2 only), 100 mm (stroke 1 only), and 150 mm (both strokes extended, total travel). The positions are fixed by the two piston sections and are selected by pressurizing the appropriate cylinder ports.
The SCT63X100X50S integrates two piston sections on a single common rod, which saves significant axial space and simplifies mounting compared to coupling two individual cylinders back-to-back. It also reduces the number of flow controls and fittings required. The force output per section is identical to a standard SC63 cylinder (1559 N push at 0.5 MPa), but the tandem design guarantees the rod alignment and position sequence are mechanically fixed.
