Airtac SCD Standard Cylinder SCD100X1000S
The AirTAC Airtac SCD Standard Cylinder SCD100X1000S 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, 1000mm stroke, PT1/2 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD100X1000S
The SCD100X1000S is a double-acting, double-rod pneumatic cylinder that delivers perfectly symmetrical force in both directions, calculated at 3681 N at 0.5 MPa. With a 100 mm bore and a 25 mm through-rod extending from both end caps, the effective piston area is identical on the push and pull strokes, making it ideal for applications where balanced speed and thrust are critical.
This model features a 1000 mm stroke and comes with a built-in magnet (suffix -S), allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for contactless position feedback. The PT1/2 port, adjustable air cushion (29 mm), and a body length A(SCD) of 263 mm provide a robust platform for long-stroke, dual-sided tooling tasks.
Airtac SCD Standard Cylinder SCD100X1000S Technical Specifications

|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø100 mm |
| Rod diameter | Ø25 mm (both ends) |
| Stroke | 1000 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 SCD100X1000S Is Used
Reciprocating Transfer Shuttles
The equal push-pull force of 3681 N at 0.5 MPa ensures a consistent, powerful stroke in both directions for moving parts between two stations on a shuttle table.
Dual-Sided Bending or Forming
Attach tooling to both rod ends to perform a forming operation on the outstroke and a secondary operation on the return, doubling throughput with one actuator.
Long-Stroke Position Sensing
The built-in magnet allows CMSG/DMSG sensors to be placed anywhere along the 1000 mm stroke, providing precise, adjustable end-of-stroke or mid-stroke signals for complex sequences.
Is the Airtac SCD Standard Cylinder SCD100X1000S the Right Cylinder?
Choose the SCD100 bore when your application requires around 3681 N of balanced force at standard plant pressure. If your load is lighter, stepping down to an SCD80 bore (2268 N at 0.5 MPa) can reduce air consumption and physical size. For applications needing force in only one direction, a single-rod SC series cylinder is a more economical choice. For drop-in replacement, match the 100 mm bore, 1000 mm stroke, PT port thread, basic mounting, and the -S magnet option.
At a 1000 mm stroke, the long, unsupported rod on both ends is susceptible to bending under side loads. If the load is not guided externally, consider adding a linear guide or switching to a guided cylinder to prevent rod bearing damage and ensure reliable operation.
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 SCD100X1000S FAQ
The force is identical in both directions because the rod passes through both ends. At 0.5 MPa it is 3681 N, at 0.7 MPa it is 5153 N, and at the maximum operating pressure of 0.9 MPa it reaches 6626 N.
Choose an SCD when you need equal force and speed in both directions, or when you need a rear rod end for mounting a sensor flag, a mechanical stop, or secondary tooling. The dual-rod support also provides better guidance against side loads than a single-rod cylinder, though it is not a substitute for a fully guided actuator under high moment loads.
