About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X60X520S
The AirTAC SCT63X60X520S multi-position cylinder delivers four distinct mechanical stop positions along its 580 mm total stroke, defined by two independent piston sections. The rod extends to 60 mm when the front section is pressurized, 520 mm when the rear section is pressurized, or the full 580 mm when both are energized, offering precise, repeatable positioning without servo complexity. Each 63 mm bore section generates 1559 N of push force at 0.5 MPa, and the 20 mm diameter rod with M16x1.5 threads is supported by a 28 mm air cushion for smooth end-of-stroke deceleration.
This model is equipped with a built-in magnet, designated by the -S suffix, allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for non-contact position sensing. The second stroke of 520 mm is a non-standard, made-to-order length, extending beyond the standard 500 mm maximum to meet specialized application requirements. The cylinder body has a base length of 249 mm, and the standard TPU seals provide reliable operation in ambient temperatures from -20 to +70 °C with PT port threads.

| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 60 / 520 mm |
| Total travel | 580 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). This configuration exceeds the 500 mm standard section stroke, so it is a non-standard / made-to-order build. 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) | 520 mm |
| P3 (both extended) | 580 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 SCT63X60X520S Is Used
Two-Stage Sorting Gate
Use the four discrete rod positions to direct packages onto four separate conveyor lanes. The 60 mm stroke selects between lanes 1 and 2, while the 520 mm stroke reaches lanes 3 and 4, all controlled by simple pneumatic valves.
Multi-Depth Pressing
Achieve two distinct pressing depths in a single cycle. The first section advances the tool to a 60 mm pre-press position, and the second section drives it to the full 580 mm depth, ensuring consistent part geometry at both stages.
Sequential Part Feeding
Control a transfer mechanism that picks a part at 0 mm, presents it for inspection at 60 mm, moves it to a wash station at 520 mm, and finally places it on an outfeed conveyor at the full 580 mm extension.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X60X520S the Right Cylinder?
Select the SCT63X60X520S when your process requires four fixed stopping points and a long secondary extension that exceeds standard stroke limits. This tandem configuration is more compact and mechanically simpler than linking two separate 63 mm bore cylinders with external stops, ensuring the position relationship between the two strokes is permanently fixed. If higher force is needed, stepping up to an 80 mm bore provides 2513 N of push per section at 0.5 MPa, while a 50 mm bore reduces force to 982 N for lighter payloads.
For direct replacement, match the 63 mm bore, the exact 60 mm and 520 mm section strokes, the PT port thread, and the built-in magnet. Since the 520 mm stroke section is non-standard, a made-to-order unit is required. When extending the rod to the full 580 mm combined travel, consider external guiding or a rod support to counteract side loading and prevent bending of the 20 mm rod.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 60 + 520 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 SCT63X60X520S FAQ
This cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 60 mm (front section extended), 520 mm (rear section extended), and 580 mm (both sections extended for total travel). The positions are fixed by the internal piston geometry and are not infinitely adjustable.
No. A standard SCT63X100X500 has different stroke lengths (100 mm and 500 mm) and will not replicate the 60 mm, 520 mm, and 580 mm stop positions of the SCT63X60X520S. You must order the exact non-standard stroke combination to match your existing tooling and process sequence.
