Airtac SED Double Rod Cylinder SED100X70S
The AirTAC Airtac SED Double Rod Cylinder SED100X70S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø100mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 70mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X70S
The AirTAC SED100X70S is a double-acting, double-rod profile cylinder conforming to the ISO 15552 mounting interface. Because a 25mm rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 3681 N of thrust in each direction at 0.5 MPa. The extruded aluminum barrel omits external tie rods, providing a clean profile with integral sensor grooves.
Fitted from the factory with a magnet (-S), this unit drives CMSE reed or DMSE electronic sensors for end-of-stroke confirmation. The twin-rod architecture excels at resisting rotational torque and allows a rear-rod cam or secondary mechanism to operate synchronously behind the cylinder.
Airtac SED Double Rod Cylinder SED100X70S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X70S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 70 mm |
| Configuration | Double rod, 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 (0–150 °C with FKM seals) |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 36 mm |
| Max stroke | Up to 1500 mm |
Specifications follow the official AirTAC SED datasheet and ISO 15552 / VDMA 24562 dimensions. Confirm against the product label before installation. Port options: PT (standard) / G (BSPP).
Theoretical Output Force (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 kgf |
Because a rod exits both ends, the effective piston area — and therefore the force — is identical on extend and retract. Actual usable force is lower than theoretical; size with a safety margin.

Where the Airtac SED Double Rod Cylinder SED100X70S Is Used
Servo Press Cam Drive
Drives an 1800kgf cam mechanism with equal extend and retract forces, using the rear rod to trigger a return limit switch.
Injection Mold Ejector
Provides 5153N at 0.7MPa to eject heavy parts symmetrically, leveraging twin rods to prevent platter rotation.
Dual-Side Material Pusher
Pushes heavy billets from both ends of a conveyor using the same 3681N force, ensuring perfectly balanced load transfer.
Is the Airtac SED Double Rod Cylinder SED100X70S the Right Cylinder?
At 0.5 MPa, this 100mm bore generates 3681 N both ways. If your payload is lighter, the 80mm bore provides 2268 N, whereas the 125mm bore offers 5734 N for heavier loads. The SED twin-rod design is preferred over a single-rod SE when an application demands anti-rotation guidance or rear-side tooling. Note that the adjustable air cushions at both ends only decelerate the load near stroke end; they do not hold position on air loss. For fail-safe holding, specify a BSED rod-lock cylinder or an external locking device. To replace an ISO 15552 unit, match the 100mm bore, 70mm stroke, PT1/2 port, and desired mounting from the SED set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Quick checklist
- ✓ Equal force/speed both directions needed?
- ✓ Back-rod space for tooling or a flag
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Support both rod ends; avoid side load.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SED Double Rod Cylinder SED100X70S FAQ
Because the double-rod design yields equal annulus areas on both sides, thrust is identical in both directions: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
The twin 25mm rods prevent rotational twist under offset loads and allow a secondary cam or sensor flag to be mounted on the rear rod end. It shares the exact ISO 15552 footprint and mounting interface as the SE series.
