Airtac SCD Standard Cylinder SCD100X260S
The AirTAC Airtac SCD Standard Cylinder SCD100X260S is a genuine double-acting DOUBLE-ROD air cylinder: the Ø25mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø100mm bore, 260mm stroke, PT1/2 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD100X260S
The SCD100X260S is a double-acting, double-rod pneumatic cylinder that produces an identical 3681 N of force in both the extend and retract strokes at 0.5 MPa, thanks to its through-rod design where the 25 mm rod subtracts the same area from both piston sides. This 100 mm bore model features a 260 mm stroke, well within the 1500 mm maximum standard stroke for this size, and includes a built-in magnet (the -S suffix) that allows barrel-mounted CMSG, DMSG, or EMSG sensors to detect piston position without external flags.
With a PT1/2 port, an M20x1.5 rod thread on both ends, and a 29 mm adjustable air cushion, the cylinder is built for balanced, two-sided tooling tasks. Its tie-rod construction and dual rod support provide better guidance than a single-rod cylinder, making it suitable for applications where the rear rod can carry a stopper, sensor target, or secondary tool. The body length A(SCD) is 263 mm, and the operating pressure spans 0.15 to 1.0 MPa.

| Stroke | 260 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| 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, 29 mm |
| Max stroke | Up to 1500 mm |
Specifications follow the official AirTAC SCD (double-rod) datasheet. Because the rod runs through both caps, the effective area is (bore² − rod²) in both directions. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø100mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | 5154 N |
| Max (@1.0 MPa) | 751 kgf | |
Push and pull are EQUAL on a double-rod cylinder — both chambers lose the rod area, so effective area = (bore² − rod²) each way. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCD Standard Cylinder SCD100X260S Is Used
Two-Sided Transfer Shuttles
The equal 3681 N push and pull force at 0.5 MPa, combined with a rod on both ends, allows a single SCD100X260S to drive a shuttle table back and forth with identical power, simplifying the pneumatic circuit and ensuring symmetrical acceleration.
Rear-Mounted Stroke Sensing
The built-in magnet (-S) enables CMSG/DMSG sensors to be clamped directly onto the barrel. The rear rod extension provides a convenient, protected location for a sensor target or cam, keeping the front tooling area clear for the primary workpiece interaction.
Non-Rotating Alignment Pushers
With a 25 mm rod extending from both ends, this cylinder offers inherent anti-rotation stability. It is ideal for pressing bearings or aligning parts where a single-rod cylinder might twist, ensuring the tooling stays square to the work surface throughout the 260 mm stroke.
Is the Airtac SCD Standard Cylinder SCD100X260S the Right Cylinder?
Choose the SCD100 when you need balanced force in both directions and the 3681 N output at 0.5 MPa fits your load. If you require more thrust, stepping up to the SCD125 provides 5734 N at the same pressure, while the SCD80 offers a lighter 2268 N if the 100 mm bore is oversized for your application. This SCD100X260S model is configured with a magnet for sensor feedback and uses the default TPU seals with PT threads.
For a direct replacement, match the 100 mm bore, 260 mm stroke, PT port thread, SCD double-rod body, and the -S magnet option. If your load needs to be held in position without continuous air pressure, an external rod lock or pilot-operated check valve must be added, as the air cushion only decelerates the piston and will not prevent drift. At this 260 mm stroke, the dual-rod design resists rotation well, but significant side loads still require an external guide or a dedicated guided cylinder.
Double-rod checklist
- ✓ Need equal force / speed both directions?
- ✓ Rear rod for tooling, stopper or sensor flag?
- ✓ Better rod guidance / anti-rotation?
- ✓ 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 Keep BOTH rod ends clear of side load and interference.
- check Adjust end cushion screws for smooth stops.
- check Use SCD mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCD Standard Cylinder SCD100X260S FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 3681 N, at 0.7 MPa it produces 5153 N, and at the maximum operating pressure of 0.9 MPa it produces 6626 N. The theoretical force at 1.0 MPa is 751 kgf.
Choose the SCD when you need equal force and speed in both directions, or when you require a rear rod extension for mounting a second tool, a mechanical stop, or a sensor flag. The dual-rod design also provides better guidance and anti-rotation compared to a single-rod SC cylinder of the same bore, though it is not a replacement for a fully guided cylinder under heavy side loads.
