About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X33X62SN
The SCT32X33X62SN is a double-acting multi-position tandem cylinder that delivers four distinct rod stops—0 mm, 33 mm, 62 mm, and the full combined travel of 95 mm. By pressurising the two piston sections independently or together, you get repeatable mechanical indexing without complex controls. Each 32 mm bore section generates 402 N of push force at 0.5 MPa, and the 12 mm diameter hard-chrome-plated rod handles the offset loads common in compact sorting tasks.
This specific model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke or mid-position confirmation. It is fitted with NBR (nitrile) seals, making it a solid choice for general industrial air service within the standard -20 to +70 °C range. The body length A(SCT) is 233 mm, and the adjustable pneumatic cushion at each end section absorbs energy smoothly to protect the end caps during high-cycle operation.

| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 33 / 62 mm |
| Total travel | 95 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) | 33 mm |
| P2 (section 2) | 62 mm |
| P3 (both extended) | 95 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 SCT32X33X62SN Is Used
Multi-Stop Diverter Gates
Use the four discrete positions (0, 33, 62, 95 mm) to route small packages or components to three separate conveyor lanes from a single infeed point, with the retracted position serving as a neutral or fourth lane.
Two-Depth Pressing & Staking
Achieve a shallow 33 mm pre-press and a deeper 62 mm final staking depth in assembly fixtures. The 95 mm full-extension position can be used for part ejection or clearing the tooling area.
Sequential Clamping & Feeding
Control a two-stage material feed in packaging or woodworking machinery. The first 33 mm stroke advances a stop gate, the 62 mm stroke feeds material, and the combined 95 mm stroke retracts the gate fully for the next cycle.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X33X62SN the Right Cylinder?
Choose the SCT32 when your application needs up to four fixed mechanical stops from a single tie-rod assembly, saving the cost and plumbing of two separate cylinders with external hard stops. If the 402 N push force per section (at 0.5 MPa) is marginal, stepping up to the SCT40 provides 628 N per section. For a direct replacement, match the 32 mm bore, both strokes (33 mm and 62 mm), the PT port thread, the built-in magnet (-S), and the basic mounting configuration. Note that the 33 mm section stroke is a non-standard value, so this is a made-to-order configuration—ensure your system design can accommodate the exact 95 mm total travel before ordering.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 33 + 62 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 SCT32X33X62SN FAQ
This tandem cylinder provides four discrete mechanical stop positions: 0 mm (fully retracted), 33 mm (first section extended), 62 mm (second section extended), and 95 mm (both sections extended, total travel). The positions are achieved by pressurising the two piston sections individually or simultaneously.
Yes, if you need the specific 33 mm and 62 mm strokes. The SCT32X33X62SN integrates both strokes into one tie-rod body, which simplifies mounting and eliminates the need to synchronise two separate cylinders. A direct replacement must match the 32 mm bore, both strokes, the PT port thread, the built-in magnet for sensors, and the NBR seal material.
