About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X98X260S
The SCT32X98X260S is a double-acting tandem cylinder that delivers four fixed rod positions from two independent piston sections on a common rod line. With strokes of 98 mm and 260 mm, the accessible stops are 0 mm (fully retracted), 98 mm, 260 mm, and 358 mm (total travel). Each section provides 402 N of push force at 0.5 MPa, making it suitable for light-duty multi-stop feeding or sorting tasks.
This 32 mm bore model features a 12 mm diameter rod, PT1/8 ports, and an M10x1.25 rod thread. The integrated magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for position feedback. The body length A(SCT) is 233 mm, and the cushion length is 21 mm per end, providing consistent deceleration across all stops.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X98X260S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 98 / 260 mm |
| Total travel | 358 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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) | 98 mm |
| P2 (section 2) | 260 mm |
| P3 (both extended) | 358 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCT32X98X260S Is Used
Two-Stage Part Diverting
Use the 98 mm stroke to clear a gate and the 260 mm stroke to push a part onto a second conveyor lane, achieving reliable 4-position sorting.
Multi-Depth Assembly Press
The four discrete stops allow a pressing tool to reach a pre-load position (98 mm), a partial insertion depth (260 mm), and a final seat depth (358 mm) in one cycle.
Sequential Label Application
Apply a label at the 98 mm stop on one product face, then extend to 260 mm to wrap the label around a corner, using sensors on the magnet-equipped barrel for timing.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X98X260S the Right Cylinder?
Choose this SCT when your application needs four distinct mechanical stops without the complexity of servo control or the footprint of two separate cylinders. The 98 mm and 260 mm stroke combination is ideal for a two-stage feed where a short advance is followed by a longer secondary stroke. If you require higher force, stepping up to the 40 mm bore provides 628 N of push per section at 0.5 MPa.
For direct replacement, match the bore (32 mm), both strokes (98 mm and 260 mm), PT port thread, and the -S magnet option. Since the 260 mm section stroke exceeds 250 mm, consider external guiding or a rod support to manage side-loading and prevent rod deflection during extension.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 98 + 260 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 SCT32X98X260S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 98 mm (first section extended), 260 mm (second section extended), and 358 mm (both sections extended, total travel).
Yes, if your sequence requires the 98 mm and 260 mm strokes. The SCT32X98X260S consolidates two moves into one compact tie-rod body. Ensure the replacement matches the 32 mm bore, both stroke lengths, PT ports, and the -S magnet option for sensor compatibility.
