About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X610X270S
The SCT32X610X270S is a double-acting multi-position cylinder that delivers four discrete rod stops from two tandem piston sections: 0 mm, 270 mm, 610 mm, and the full 880 mm extension. Each 32 mm bore section provides 402 N of push force at 0.5 MPa, driven through a 12 mm diameter piston rod with PT1/8 ports and M10x1.25 rod-end threads.
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to be directly mounted on the tie-rod barrel for non-contact position sensing at any of the four stops. Both strokes exceed the standard 500 mm range, classifying this as a made-to-order configuration with a 21 mm air cushion on each section to manage end-of-stroke energy.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X610X270S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X610X270S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 610 / 270 mm |
| Total travel | 880 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). 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) | 610 mm |
| P2 (section 2) | 270 mm |
| P3 (both extended) | 880 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 SCT32X610X270S Is Used
Multi-Stop Part Feeding
Advances a pusher plate to three distinct positions—270 mm, 610 mm, and 880 mm—to stage different-sized components on a conveyor line for sequential processing.
Two-Depth Press Operation
Executes a shallow 270 mm pre-press stroke and a deep 610 mm main press stroke, with the 880 mm total travel used for part ejection, all from one compact unit.
4-Way Sorting Gate
Positions a diverter gate at four fixed angles to route packages into four separate lanes, using magnetic sensors at each stop for positive confirmation.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X610X270S the Right Cylinder?
This tandem unit replaces the need for two separate 32 mm bore cylinders and external hard stops when a sequence of four precise linear positions is required. If the application demands higher force, stepping up to the 40 mm bore SCT40 series provides 628 N of push per section at 0.5 MPa. For replacement compatibility, match the 32 mm bore, both the 610 mm and 270 mm strokes, the PT port thread, basic mounting, and the -S magnet option.
Given the 610 mm stroke on the first section, rod buckling and side-loading must be carefully evaluated. It is recommended to guide the external load with a linear rail or rod support to prevent bending moments from damaging the 12 mm rod and internal bearings.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 610 + 270 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 SCT32X610X270S FAQ
The four discrete rod positions are fully retracted (0 mm), first section extended (270 mm), second section extended (610 mm), and both sections extended for the total travel of 880 mm.
No, the SCT is a pneumatic cylinder and will drift if air pressure is lost or valves are centered. To hold a load at any of the four stops without live pressure, you must add an external rod lock or a pilot-operated check valve.
