About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X100
The SCT63X50X100 is a tandem multi-position pneumatic cylinder that provides four fixed rod positions: fully retracted (0 mm), 50 mm, 100 mm, and the total travel of 150 mm. Each 63 mm bore piston section generates 1559 N of push force at 0.5 MPa, making it a robust solution for diverting or sorting tasks that require more than two end-of-stroke locations.
This double-acting unit features a 20 mm diameter piston rod and PT1/4 ports. The integrated adjustable air cushion on each section, with a 28 mm cushion length, decelerates the load smoothly at every stop. The tie-rod construction keeps the body length to a compact 249 mm base dimension (A), simplifying integration into multi-stop feeding systems.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X100 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 50 / 100 mm |
| Total travel | 150 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, 28 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) | 100 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 SCT63X50X100 Is Used
Four-Way Part Diverting
Direct packages or components to four separate conveyor lanes by pressurising section one, section two, or both, achieving precise 50 mm, 100 mm, and 150 mm gate positions from a single retracted home.
Multi-Depth Press Insertion
Insert bushings or pins to two different controlled depths in sequence. The 50 mm stroke handles a shallow press, while the 100 mm section completes a full-depth insertion, all with 1559 N of force per stage at standard line pressure.
Staged Clamping Fixture
Operate a two-stage clamp that first applies a light contact position at 50 mm, then a full clamping stroke at 100 mm. The discrete stops ensure repeatable clamping force without over-travel, protecting delicate workpieces.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X50X100 the Right Cylinder?
Choose the SCT63X50X100 when a single actuator must move a load to four distinct positions without the complexity of two separate cylinders and external hard stops. If your application requires higher force, stepping up to the 80 mm bore SCT80X50X100 provides 2513 N of push per section at the same 0.5 MPa pressure. For a direct replacement, match the 63 mm bore, both strokes (50 mm and 100 mm), PT port thread, and basic mounting configuration exactly.
When the combined stroke reaches 150 mm, ensure the rod is adequately guided if significant side loads are present. The 20 mm rod diameter provides good rigidity for axial pushing, but an external guide rail is recommended for off-centre masses to prevent bending and premature seal wear.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 50 + 100 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 SCT63X50X100 FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 50 mm (first section extended), 100 mm (second section extended), and 150 mm (both sections extended). The positions are fixed by the two internal piston strokes and are not infinitely adjustable.
Yes, if your sequence requires a 50 mm and a 100 mm stroke from the same rod line. The SCT integrates both strokes into a single tie-rod body, eliminating the need to synchronise two separate actuators and their mounting brackets. Ensure the replacement matches the PT1/4 port thread and basic mounting style.
