Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X100
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X100 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 60mm and 100mm give 4 controllable stop positions across a 160mm total travel, with a Ø50mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X100
The SCT50X60X100 tandem cylinder delivers four fixed rod positions—0 mm, 60 mm, 100 mm, and the full 160 mm extension—by pressurising its two 50 mm bore sections independently or together. Each actuated piston section generates 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa), driven through a 20 mm diameter rod with M16x1.5 threads and PT1/4 ports.
With a 21 mm adjustable air cushion in each section and a body length A of 243 mm, this tie-rod design decelerates loads smoothly at both intermediate and full-travel stops. The unequal strokes create four distinct positions without external hard stops, making it a compact alternative to two separate cylinders for sequenced movements.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X100 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X100 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 60 / 100 mm |
| Total travel | 160 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) | 100 mm |
| P3 (both extended) | 160 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 SCT50X60X100 Is Used
Two-Depth Pressing
Stop at 60 mm for a pre-compression step and 160 mm for full insertion, using the intermediate 100 mm position for part ejection.
Multi-Lane Sorting
Direct packages to four separate conveyor lanes by stopping a diverter gate at 0, 60, 100, and 160 mm positions.
Staged Clamping
Apply a light clamp at 60 mm for alignment, then full clamping force at 100 mm, with a 160 mm retracted safe position for loading.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X60X100 the Right Cylinder?
Choose the SCT50X60X100 when your application requires four fixed stopping points within a 160 mm envelope, such as a two-depth pressing station or a multi-lane diverter. If the 982 N per-section push at 0.5 MPa is marginal, stepping up to the 63 mm bore provides 1559 N per section; if space is tight, the 40 mm bore delivers 628 N. This model is a direct replacement for another AirTAC SCT50X60X100 with PT ports and basic mounting—verify both stroke sections and port thread match exactly. For strokes over 300 mm, assess side-loading and consider external guides to protect the rod bearings.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 60 + 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 SCT50X60X100 FAQ
It provides four discrete mechanical stops: 0 mm (fully retracted), 60 mm (section one extended), 100 mm (section two extended), and 160 mm (both sections extended). The positions are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, in many cases. The SCT50X60X100 integrates two piston sections on one common rod, giving you four fixed positions without the alignment complexity and extra mounting hardware of two individual cylinders. Ensure the per-section force (982 N push at 0.5 MPa) meets your load requirements at each stop.
